HDPE Fusion Procedures August, 2010 3 Roth Avoid pipe that is not black in color and pipe that does not have “C” as the UV stabilization digit in the cell classifiion. Along with the correct ground loop piping, fittings must meet requirements for O.D. controlled
Butt-Fusion (BF) and Electro-Fusion (EF) welding processes are the most common joining processes for HDPE pipelines. Defects for BF welds include planar flaws due to poor welding processes, cold fusion welds caused by incorrect welding procedures, inclusion of particulates and weld mismatch.

Butt fusion involves the simultaneous heating of the ends of two pipe/fitting components which are to be joined, until a molten state is attained on each contact surface. The two surfaces are then brought together under controlled pressure for a specific cooling time and a homogeneous fusion joint is formed.
4.3 The socket fusion, butt fusion, and saddle fusion procedures in this practice are suitable for joining PE gas pipe and fittings, PE water pipe and fittings, and PE general purpose pipes and fittings made to PE product specifiions from organizations such as ASTM, AWWA, API, and ISO that are used in pressure, low pressure and non-pressure appliions.
Our service personnel are factory certified and trained in the proper procedures for using both heat fusion and electrofusion to form strong and durable joints with Polyethylene pipe. Experience has shown that a joint made by a properly trained person, using proven fusion procedures and that passes a visual inspection based on proper bead formation, will have strength characteristics Puhui Pipe manufacturer in China
Butt fusion welding is the name given to hot plate welding of thermoplastic pipes. It is one of two main techniques for the fusion joining of polyethylene gas and water pipe. The Process The heating phase, sometimes referred to as ''bead up'', is where the pipe ends Puhui Pipe manufacturer in China

Fusion Joining Procedure, TR-41 and its Generic Butt Fusion Joining Proce-dure, TR-33 as their foundations. HDPE pipe and fittings manufacturers have approved PPI’s Generic Joining Procedures in an attempt to standardize the joining procedures of HDPE. For
The surface temperatures must be in the temperature range 400 - 450 F (204 - 232 C). Install the heater in the butt fusion machine and bring the pipe ends into full contact with the heater at fusion pressure to ensure that full and proper contact is made between the
Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself. The principle of
Plastics pipes and fittings — Butt fusion jointing procedures for polyethylene (PE) piping systems ISO 21307:2017 establishes general principles regarding the procedure used in the construction and quality assessment of butt fusion jointing of polyethylene (PE
3 Butt fusion procedures according ISO 21307 The introduction of the standard ISO 21307 says: With the increasing use of bimodal polyethylene (PE) materials such as PE 80 and PE 100, more and more PE compounds are appearing on the pipe market accompanied by proposals for butt fusion procedures that often differ for the same materials.

For this job, Ketek was fusing HDPE pipe that was 20 inches in diameter. It came in 55-foot lengths which we “butt fused” together. The operator of the butt fusion machine first machines the pipe to make the two ends perfectly flush. He then heats them to a set
The butt-fusion method of joining is by far the most common method of connecting polyethylene pipe in all diameters. The ends of polyethylene pipe when heated and brought together under pressure with specialized equipment form one continuous “leak proof” pipeline. Properly made, a pipe fusion is as strong as the pipe itself and has the […]
