1. Cut pipe to length using appropriate cutters.2. Use scraper BWPS 16063 to remove oxide layer from pipe for full fitting insertion length to approximate depth of 0.3mm. 3. Wipe surfaces to be welded with Welding Wipes (BEFPW) to remove dust etc, and allow cleaner to evaporate. 4. Assemble pipe and fitting making sure pipe is FULLY inserted. Clamps may be attached to stabilise joint during welding.

5. Connect welder leads onto fitting terminals. Set correct weld time (marked on each fitting). Follow instructions for particular welder. Press start for weld cycle to commence. Allow to cool, time is marked on each fitting. 6. Rising melt indicators confirm successful completion of weld. When weld cycle is completed, allow assembly to cool without any movement or strain.

Electro Fusion

Fittings for electro fusion comply with AS4129. Automatic control box reads resistor and sets and welds the correct time, fittings also labelled for manual setting times. Weld surfaces must be clean and dry.

Do not overscrape pipe. Use correct scrapers.

Do not use emery paper or metal files. IMPORTANT: Do not allow movement in the joint until cooling period has been completed. In some cases clamps may be required. Ensure continuous electricity supply during weld cycle.


Socket fusion

Heating element socket fusion to welding guideline AS 2033-1980. Weld surfaces must be clean and dry. Welding machine must be up to temperature 230° – 250° C before commencing. Avoid cold windy conditions. Do not realign joint after adjusting time, see table below. Do not overscrape pipe – interference fit must be retained. Do not twist pipe into fitting when fusing.

1. Turn on Welder BSFHM. Do not attempt welding unless tool is up to temperature (250°C). The light will flash on/off with thermostat control when temp. is correct.2. Cut pipe to length required with (BPC…) cutters for a swarf free finish. 3. Clean pipe & fitting. Use scraper (BWPS…) to remove oxide layer from pipe and ensure correct tolerance. Welding wipes (BEFPW) may be used if required. 4. Simultaneously insert pipe and fitting onto socket and spigot to full depth without twisting. Hold for correct time as per table ‘Pre-heating seconds’ (left)

5. Remove pipe & fitting from heating element, immediately insert pipe into fitting without twisting. 6. Check alignment within ‘adjusting seconds’ as per table (left). During cooling avoid mechanical strain or movement on welded joint.

Compression Fittings

CompressionFitting20to63_1 CompressionFitting20to63_2 CompressionFitting20to63_3
1. Cut pipe to length with appropriate cutter (BPC…) for a swarf-free finish. 2. Chamfer with appropriate chamfering tool. (BCHAM…) This may not be necessary for BLUTUBE 20, 25, 32. 3. Remove nut and conical grip ring from fitting and mount on pipe in the same order with the large end of the grip ring facing fitting. Lubricate, see notes*, **.
CompressionFitting20to63_4 CompressionFitting20to63_5
4. Insert the pipe into fitting with a twisting motion until it passes through the ”0” ring and meets the internal shoulder. Ensure that grip ring is touching the fitting. 5. Screw and tighten the nut onto the fitting firmly by hand. The larger pipe sizes 40mm & upward will need tightening with the appropriate wrench (BNW1) however, do not use excessive torque.

** Lubricate with silicone spray, soapy water or vaseline except on specialist applications. ie: powder coating, spray painting, breathing & quality air, etc. DO NOT use penetrating fluids such as WD40, 5-56, Penetrene etc.

1. Cut pipe to length and chamfer.2. Remove nut, conical grip ring, bushing and ”0” ring and mount on pipe in the same order leaving out grip ring.3. Lubricate pipe end and inside of fitting. (See note below**) 4. Insert pipe into the fi tting until it meets the internal shoulder. 5. Bring up the ”0” ring and bushing and tighten nut until they are fully in place.

6. Unscrew nut, open grip ring and put on pipe with the large end touching the bushing. 7. Tighten nut with the appropriate wrench (BNW2) taking care not to use excessive force.*Fitting may be supplied with a tapered seal instead of O-Ring,
– in this case nut need not be removed,
– simply chamfer pipe, lubricate, fully insert, and tighten.

** Lubricate with silicone spray, soapy water or vaseline except on specialist applications. ie: powder coating, spray painting, breathing & quality air, etc. DO NOT use penetrating fluids such as WD40, 5-56, Penetrene etc.
