Bingo Pipeline has a wide range of butt fusion welding HDPE fittings in accordance with the ISO 4427, EN12201,AS/NZS 4129 PE Fittings, ISO4437 standards etc. From the diameter OD50 to 1200mm, could be used for water supply, oil and gas transmission. The pressure rate PN10, PN12.5, PN16, PN20, PN25 are available for options.

Butt fusion can be used for jointing pipes and fittings 63mm diameter and larger. However it is most commonly used for larger diameter pipes. Butt fusion jointing is equally suited to both coiled pipes and straight pipe lengths. Only pipes and fittings of the same nominal diameter may be butt fused.

Butt fusion can be used in new installations using traditional open cut trenching techniques. Additionally due to the low profile of the butt joint it is ideal for use in trenchless technology installations, sliplining, pipe bursting, directional drilling, etc.

Please check above list and find our butt fusion fittings type and the diameter & pressure class ranges. These fittings are safe and reliable for a range of applications across many different industries.

All the PE butt fusion fittings are made from the PE100 material, same with the pipes. Butt fusion end PE pipes can be joined by butt fusion thus avoiding the need for a fitting. Some spigot end fittings like tee, elbow, end cap, stub ends and so one are produced specifically for butt fusion to pipe. These must be specified to match both the pressure rating and the SDR of the pipe. It is normally not acceptable to use a butt fusion fitting of a different SDR rating to that of the pipe even if the pressure rating of the fitting is equivalent or higher than that of the pipe.

PE pipes of the same outside diameter but having different specified wall thicknesses (i.e., different DR designations) may be butt fused to each other under special conditions, but is subject to limitations, requiring consultation with the pipe manufacturer.

In some pipe systems, engineers may elect to remove the inner or outer bead of the joint, using appropriate tools and procedures. Since the fusion must be completely cooled before bead removal, assembly time is increased slightly. However, it is uncommon to remove internal beads, as they have little or no effect on flow, and removal is more time-consuming, requiring use of a cutter fitted to a long pole following each fusion.

The most widely used method for joining individual lengths of PE pipe and pipe to PE fittings is by heat fusion of the pipe butt ends (butt fusion). This technique produces a permanent, economical and flow-efficient connection. PPI Technical Report TR-33, Generic Butt Fusion Joining Procedure for Field Joining of Polyethylene Pipe and ASTM International F 2620, Standard Practice for Heat Fusion Joining of Polyethylene Pipe and Fittings and ASTM International F 2620, Standard Practice for Heat Fusion Joining of Polyethylene Pipe and Fittings, provide recommended practices for the generic butt fusion joining procedure.
