Common field situations and the Lanbo products that fit them. Each entry gives the equipment and conditions, how customers usually ask, what to do, the products that apply and a detailed guide.

### Chiller evaporator tubes froze and split: emergency retube
- Situation: Centrifugal or screw chiller, shell-and-tube evaporator or condenser with copper tubes (typically 3/4 in or 5/8 in internally enhanced). Water left in the barrel froze during shutdown or low-load operation; tubes split, water got into the refrigerant side and the system will not pull a vacuum.
- Customers ask: "Chiller tubes froze. Plug them or retube the whole barrel?"; "A dozen evaporator tubes are split. How do we pull and replace them?"; "How do we make sure the new rolled joints do not leak?"
- What to do: Eddy current test first to find every damaged tube (done by a testing contractor). Plug a few; retube when the plugging percentage gets too high or damage is widespread. Sequence: pull old tubes, clean the tube holes, install new tubes, roll to a set torque, pressure and leak test.

### Leaking rolled joints in a chiller or exchanger: re-roll before you plug
- Situation: Shell-and-tube condenser, evaporator or oil cooler where the tubes are sound but the leak is at the tube-to-tubesheet rolled joint. Common on older units, units with vibration, or joints that were over- or under-rolled.
- Customers ask: "The leak is at the tube sheet. Can we re-roll the tube instead of plugging it?"; "How do we find which of thousands of rolled joints is leaking?"; "What torque do we re-roll at without loosening the neighbouring joints?"
- What to do: Find the leaking joints one by one with a vacuum joint leak detector, re-roll them with a torque-controlled tube roller at the original rolling torque, then re-test. Plug only if a joint still leaks or the tube end is cracked. Check the roller torque with a torque tester; over-rolling damages the ligaments and starts new leaks.

### Annual chiller maintenance: brushing ("punching") condenser and evaporator tubes
- Situation: Water-cooled chiller condenser or evaporator opened at the annual shutdown; every tube (smooth or internally enhanced copper) is brushed through with water. Deposits are soft scale, silt and biofilm; condenser approach temperature and energy use have crept up. A large machine has more than a thousand tubes and takes days to rod by hand.
- Customers ask: "Fastest way to brush chiller condenser tubes?"; "Which brushes for internally enhanced tubes without damaging them?"; "Can one tech punch a 1,000-tube barrel in a shift?"
- What to do: Use a rotary flexible-shaft tube cleaner that flushes water while the brush turns; use brushes made for enhanced tubes. Drain the water side and pull the heads first; check tube ends and head gaskets afterwards. For hard scale, soak with a descaling chemical first, then brush.

### Tubes packed solid with hard scale, coke or sand: a brush will not go through
- Situation: Refinery reboiler and exchanger bundles, power plant air preheaters and condensers, gas coolers, boiler water-wall tubes. Tubes are completely blocked with asphalt-bound sand, coke or hard scale; brushes and hydroblasting will not clear them and reamers can get stuck.
- Customers ask: "Reboiler tubes are packed with sand and asphalt. How do we clear them?"; "What clears tubes that hydroblasting cannot?"; "The reamer got stuck in a tube. Now what?"
- What to do: Drill through section by section with a plugged-tube cleaner fitted with drill or milling heads (high-power motor, variable speed; flexible-shaft versions for bent tubes), then finish with brushes. If the tubes cannot be cleared or the walls are damaged, replace the bundle.

### Fire-tube boiler retube: cut out the old tubes, roll and bead the new ones
- Situation: Gas- or oil-fired fire-tube boilers, steam locomotive boilers and industrial steam boilers, with tubes typically 1-1/2 to 3 in OD. Corroded or leaking tubes, or heavy scale, call for a full retube. Tubes are rolled and beaded at the tubesheet; first-pass tubes are sometimes welded.
- Customers ask: "How do you pull and replace fire-tube boiler tubes?"; "Do boiler tubes need beading after rolling, and what does it in one pass?"; "What tube roller torque for 2 in and 3 in boiler tubes?"
- What to do: Cut the old tubes inside the tubesheet and pull them; install the new tubes and roll and bead in one operation with a combination beading expander, or roll first and then bead or flare. Use a high-torque electric tube roller for large thick-wall tubes; weld where the boiler design calls for it.

### Scale and coke in boiler tubes, water walls and furnace tubes
- Situation: Soot and carbon in fire-tube boiler tubes; scale and coke inside water-tube, waste-heat boiler and fired-heater tubes. Oil-fired boilers build up carbon faster. Straight, bent and S-bend tubes.
- Customers ask: "How do you clean carbon out of boiler fire tubes?"; "What cleans scale inside bent water-wall tubes?"; "Which cleaner and head for which tube ID?"
- What to do: Straight tubes: a straight-tube cleaner with cutter or brush heads. Bent tubes: a flexible-shaft or curved-tube cleaner. Choose the head by tube ID. After cleaning, check for wall loss and replace thinned tubes.

- Detailed guide: [Cleaning Scale from Boiler Tubes](https://hflanbo.com.cn/en/wenti/guolu-guan-qingli.md)

### High plugging rate in power plant feedwater heaters or condensers: plug or retube at the outage
- Situation: Condensers, HP/LP feedwater heaters and closed cooling water exchangers on thermal and nuclear units. Eddy current testing shows many tubes with wall loss; plugging is already at 10–20% and the outage window is short.
- Customers ask: "Our feedwater heater is 20% plugged. Can we keep plugging?"; "At what plugging percentage should a condenser be retubed?"; "We only have a few weeks of outage. Can we retube in time?"
- What to do: Decide from the eddy current results and whether the unit still meets its duty with the tubes plugged. Retube when plugging keeps rising or thinned tubes are grouped together. Plan the retube from the tube count, material, welding and site conditions; a complete tool set and crew shortens the schedule.

### Pulling old tubes on a retube: tubes will not come out or break off in the tubesheet
- Situation: Condenser and heat exchanger retubes where old tubes are corroded, scaled or tightly rolled; pulling by hand is slow and tubes snap. Broken tube stubs stay stuck in the tubesheet holes. Stainless steel and titanium are harder to pull.
- Customers ask: "Condenser tubes will not pull. What now?"; "A tube broke off in the tubesheet. How do we get it out?"; "How do we pull thousands of tubes quickly?"
- What to do: Cut the old tubes inside at the support plate or tubesheet with an internal tube cutter, then pull with a hydraulic tube puller and spear; collet-type spears need no screwing in and are faster. Remove stubs left in the holes with a stub puller, tube knockout tool or collapsing tool.

### Internal leak in a condenser or cooler: find the leaking tube fast
- Situation: Rising condensate conductivity in a power plant condenser, oil and water mixing in marine or industrial coolers, water getting into a chiller refrigerant circuit. With thousands of tubes, pressurising the shell and listening or soap-testing tube by tube is slow.
- Customers ask: "How do you find leaking condenser tubes quickly?"; "Our shell-and-tube cooler has an internal leak. Which tube is it?"; "Once found, plug or retube?"
- What to do: Isolate a section and test each tube with a vacuum tube leak detector, a few seconds per tube and no water needed; test the rolled joints with a vacuum joint leak detector. Mark the leakers, plug or replace them, then re-test.

### Refinery and chemical plant turnarounds: rolling tubes in hazardous areas
- Situation: Exchangers rolled in place during a turnaround inside a classified area where ordinary electric tools are not allowed; carbon steel and alloy thick-wall tubes needing high torque.
- Customers ask: "What tube roller can we use in a hazardous area?"; "Does an air tube roller have enough torque for thick-wall tubes?"; "Hydraulic or air-driven tube roller?"
- What to do: For low to medium torque use an air-driven torque-control tube roller (spark-free, stops at the preset torque). For thick-wall, large-diameter tubes use a hydraulic explosion-proof tube roller. Choose the expander from tube OD, wall and tubesheet thickness.
- Products that fit: [850 Series Air-Driven Explosion-Proof Tube Rollers](https://hflanbo.com.cn/en/product/1021.md), [HyDrive Series Hydraulic Explosion-Proof Tube Roller](https://hflanbo.com.cn/en/product/991.md)

### Thick-wall, large-diameter steel tubes that an ordinary roller cannot expand
- Situation: Carbon and alloy steel thick-wall tubes, 45–159 mm OD, in waste-heat boilers, HP heaters and process exchangers; ordinary rollers lack the torque, joints stay loose or expanders fail.
- Customers ask: "What tube roller for large thick-wall tubes?"; "How much torque to roll steel tubes over 3 in?"
- What to do: Choose a high-torque electric or hydraulic tube roller by tube OD, with a matching expander; clean the holes and set the torque from trial rolls.
- Products that fit: [DZ-C 76 Electric Tube Roller](https://hflanbo.com.cn/en/product/885.md), [DZ-C 108 Electric Tube Roller](https://hflanbo.com.cn/en/product/886.md), [DZ-C 159 Electric Tube Roller](https://hflanbo.com.cn/en/product/887.md), [HyDrive Series Hydraulic Explosion-Proof Tube Roller](https://hflanbo.com.cn/en/product/991.md), [XR Series High-Torque Servo Tube Roller with Telescopic Shaft](https://hflanbo.com.cn/en/product/889.md)

### Rolling at intermediate tubesheets, double tubesheets and thick tubesheets
- Situation: Large exchangers and condensers with intermediate tubesheets or support plates, double-tubesheet designs, or tubesheets over 100 mm thick; joints must be rolled metres from the tube end and the rolled ID measured.
- Customers ask: "How do we roll at an intermediate tubesheet the expander cannot reach?"; "What to watch for on double-tubesheet exchangers?"; "How do we check deep rolled joints?"
- What to do: Use long-reach expanders (reach up to 5 m) with a high-torque roller; roll in steps to avoid over-rolling; measure the rolled ID with a tube ID gauge.
- Products that fit: [LH Series Expander](https://hflanbo.com.cn/en/product/902.md), [H5 Series Expander](https://hflanbo.com.cn/en/product/900.md), [H Series Expander](https://hflanbo.com.cn/en/product/901.md), [XR Series High-Torque Servo Tube Roller with Telescopic Shaft](https://hflanbo.com.cn/en/product/889.md), [SR Series Servo Tube Rolling System](https://hflanbo.com.cn/en/product/946.md), [Tube ID Gauge for Rolled Joints](https://hflanbo.com.cn/en/product/994.md)
- Detailed guide: [Rolling at Intermediate Tubesheets, Double Tubesheets and Thick Tubesheets](https://hflanbo.com.cn/en/wenti/shenkong-zhangjie.md)

### Heat exchanger and pressure vessel fabricators: consistent, traceable rolled joints and higher output
- Situation: Shell-and-tube exchanger, condenser, evaporator and desalination equipment shops. Owners and inspectors want a torque record for every joint; skilled operators are scarce, so one operator must run several tools at a steady cycle time.
- Customers ask: "How do we export rolling records for the inspector?"; "How many tube rollers can one operator run?"; "What tools for a new line: rolling, trimming, welding?"
- What to do: A servo tube rolling system holds constant torque and records every joint (USB export); a dual-servo unit rolls two tubes at once. Add tube end facing tools, grooving tools and a torque tester; an orbital TIG tube-to-tubesheet welder where joints are welded; a tube installation robot for high volume.

### Tube-to-tubesheet welding: autogenous welds on thin-wall titanium and stainless, inconsistent and slow by hand
- Situation: Nuclear, desalination and chemical equipment that calls for seal or strength welds after rolling; thin-wall titanium and stainless tubes (0.3–1.5 mm wall) where manual weld quality depends on the welder, progress is slow and welders are hard to find.
- Customers ask: "Which automatic welder for tube-to-tubesheet joints?"; "Can titanium tube ends be welded autogenously without filler?"; "How many welders can one operator run?"
- What to do: A pulsed orbital TIG tube-to-tubesheet welder welds thin-wall tubes autogenously in 18–40 s per joint depending on tube size, and one operator can run 2–3 units. Clean the tube ends first and set parameters from the welding procedure qualification.

### Rolling small copper tubes (6–12.7 mm) in condensers, oil coolers and HVAC exchangers
- Situation: Refrigeration, HVAC, oil cooler and radiator manufacture and repair with copper or steel tubes of 6.4–12.7 mm OD; thin tubes and tubesheets split or stay loose easily. This is tube-to-tubesheet rolling, not swaging copper line sets.
- Customers ask: "Which expander for small copper tubes?"; "How do we set torque on small tubes without splitting them?"
- What to do: Use expanders made for small tubes with a low-torque, torque-controlled roller and set the torque from trial rolls; use a servo or dual-servo system in production.

### Retubing in tight spaces or where there is no power or room for large equipment
- Situation: Chillers crammed into plant rooms, ship engine rooms, exchangers against a wall; little working room once the heads are off, and power on site is awkward or a battery tool is needed.
- Customers ask: "The chiller is crammed in. Where do we put the tube puller?"; "Can we roll tubes without mains power?"
- What to do: Use a portable hydraulic tube puller with a compact pump and a battery tube roller; cut tubes with a push-type internal cutter.

### Titanium condensers at nuclear and coastal plants: retube or new-build tubing on a tight schedule
- Situation: Nuclear and coastal thermal plant condensers with tens of thousands of thin-wall titanium tubes (close to 40,000 on a 1,000 MW unit) and a fixed outage window. Titanium over-rolls easily, tube ends are often welded, and owners want a full record.
- Customers ask: "What to watch when rolling titanium, and how to set torque?"; "How do we shorten the schedule for tens of thousands of titanium tubes?"; "What equipment welds titanium tube ends?"
- What to do: Roll with a constant-torque servo system that records every joint; set torque from trial rolls to avoid over-rolling; weld autogenously with an orbital TIG welder; equip every step (pull, cut, install, roll, face, weld) and run multiple shifts.

### Field pipe cutting and weld bevel preparation in power and process plants
- Situation: Boiler tube and pipe replacement that needs cold cutting and accurate V or U bevels on site, where torch cutting is not allowed or not accurate enough.
- Customers ask: "What machine for field weld bevels?"; "How do we cut large pipe in line?"
- What to do: ID-mounted beveling machines for bevels at the pipe end; OD-mounted split-frame machines cut and bevel in line in one pass; alignment clamps for fit-up.
- Products that fit: [GPN Electric Beveling Machine](https://hflanbo.com.cn/en/product/854.md), [ID-mounted Pipe Beveling Machine](https://hflanbo.com.cn/en/product/1002.md), [External Clamp Electric Pipe Cutting and Beveling Machine](https://hflanbo.com.cn/en/product/1001.md)
