This work presents the development of the Full Length Tensile Test (FLTT), a method that enables an objective judgement of welding quality of electrofusion welds by measuring the energy to break (J/mm2 ). In this paper, experimental burst tests and finite element analyses were employed to study butt fusion welded MDPE pipe joints with spherical and planar defects of various sizes. But testing begins before the welding job starts. “Butt welding involves the heating of two pipe ends to fusion temperature and then subsequently joining the two ends by the application of force. In comparison, common problems with EF welds during manufacturing include voids, lack of fusion and … Electro-Fusion Welding Method Statement Water Management Solutions. Before applying of hdpe pressure testing time may be required for the test medium and the test sample to temperature equalize. The paper is titled “Suitability of non-destructive techniques for testing polyethylene pipe joints” Peter J. Typical fusion weld detail. The recognised defect mechanisms in BF welds include embedded planar flaws due to poor welding processes, … Our team of pipe joining inspectors has the experience and certifications required to assist your company! Candidates create a test sample that is destructively crush tested during training. In this way a brittle, ductile and transitional mode failure can be differentiated without subjective visual inspection. It works by first by inserting the two ends of the HDPE pipe into the butt fusion welding machine. If it will be necessary to test the welds for a project, the tester needs to be qualified. Double seams about one inch apart are formed with an intermediary air space. Sample of PE pipe to drain completely trapped air care should be filled in the test environment. Shear testing is the basic test of strength across a weld while peel testing is used to confirm weld quality. Jackman introduces its JAC-125 Manual Socket Fusion Welder for heat fusing Socket Fusion style fittings and pipe. Hot iron socket 3. A schematic of the test … Invented by Fusion, the fusamatic pin provides a totally automatic method for ensuring the correct welding parameters are used. Non-Destructive Testing. In the Slider Settings -> Troubleshooting set option: Put JS Includes To Body option to true. Add Tip Ask Question Comment Download. Should it become apparent that a weld is faulty, the previous and proceeding weld should be tested to ascertain the extent of the faulty welding. A weld is deemed satisfactory when it yields at above 90% of the virgin mean strength and fails in a ductile mode on all profile samples. Figure 7 shows the stress–strain curves of cylinder section, dome section and weld joint. secondary power chord with renewable fitting connector plugs. Geotextiles and Geomembranes 9 (1990) 305-317 Hot Wedge Fusion Welding of HDPE Geomembranes Gary M.

The JAC-125 has a working range from 1/2"IPS to 4"IPS and welds various materials including HDPE, MDPE, PPR, PP, PVDF and PB. Their initial results were published in 2012 and presented at the PIPESXVI conference the same year. With the hot air welder, non-destructive testing is made more efficient by air pressure testing of the gap between the (dual) weld tracks the gap is pressurized by air injected through a needle inserted into the gap between weld tracks. Each company has a different name but the principle is similar. SNOQUALMIE, Wash. (June 1, 2021) - Zetec Inc., a global leader in non-destructive testing (NDT) technology, today released a new on-demand webinar featuring real-world techniques and case studies on an optimal ultrasonic inspection solution for HDPE (high-density polyethylene) butt fusion joints. A guide primarily for men and women working with HDPE pipe, whether in landfill gas systems, domestic water supply or otherwise. for Heat Fusion Joining of Polyolefin Pipe and Fittings, Annex A1. Ideally a test replicating failures seen in welds in pipe made from first generation HDPE materials with poor resistance to slow crack growth. Heat welded or Electrofusion couplers provide excellent joint integrity. A compact socket welding machine for HDPE from 63mm to 125mm.

ANS continues to deliver new testing methods for its clients in the area of inspection of HDPE Fusion Butt joints. The fusion jointing of polyethylene pressure pipeline systems using PE80 (MDPE) and PE100 (HDPE or HPPE) materials. Fusion welding consists of placing a hot metal wedge (hot shoe), mounted on a self propelled vehicular unit, between two (2) overlapped sheets of liners such that the surface of both sheets are heated above the polyethylene’s melting point. An EWI-patented process, the Weld Zone Inspection Method (WZIM) was developed in which local heat is applied to the joint region to relax the residual stresses formed by the original joining operation, which reveals the surface condition of the joint. We have experts on both metallic pipe welding and plastic pipe fusion. We have hot plates and media welders for butt welding pipe ends together, plus fusion boxes and generators for fusing pipe ends together using an HDPE electrofusion fitting. testing (NDT) options where subsequently compared to the findings from destructive examination and testing of the sample welds . Table of Contents . Find the double jquery.js include and remove it. When the electrofusion box is connected to the fitting, the Fusamatic pin enables it to automatically identify the correct fusion time … The external weld bead should be smooth and have a symmetrical profile around the whole circumference. Butt-Fusion (BF) and Electro-Fusion (EF) welding processes are the most common joining processes for HDPE pipelines. We have plastic pipe fusion welding hire available nationwide.

As a valuable added service to our customers, we can work with your design team to ensure proper best practices are implemented and that your investment is well protected or we can design your project from scratch. With the increasing demand of Medium density polyethylene (MDPE) pipes for gas transmission, the safety concern related with welding defects is becoming a serious matter. Fusion HDPE is a lightweight and highly efficient pipework system for waste and rainwater drainage. The results demonstrate clearly how lifetimes can be reduced if significant misalignments are present. Due to the arrangement of an extrusion weld peel testing can only be done from one side. 2.

There are various techniques, methods and equipment used for welding HDPE Liners. The thing is our HDPE welding machine is not automatic (butt fusion type), welder is cutting and heating the surfaces by himself. Butt-Fusion (BF) and Electro-Fusion (EF) welding processes are the most common joining processes for HDPE pipelines. HDPE butt welding put simply is the process of joining two pieces of HDPE pipe together to create a fusion weld. Our Team of Plastic Pipe WELD INSPECTOR Consultants. In this test, which is defined in Annex B of EN 12814-3, a welded whole pipe sample is subjected to a constant axial tensile load, in water at 80°C. HDPE Hydrostatic testing usually uses for hdpe water pipelines. A section has also been included related to the emerging alternative NDT technologies and aspects to consider when interpreting some destructive weld tests. The nature of defects in HDPE welds can be caused by a variety of factors and manifest themselves in different ways. Butt weld 2. A facer or facing machine is used to trim and cut the end of the pipe to create both a flat surface and to remove oxidized polyurethane. 2 3 Ridgistorm-XL Large Diameter Pipes and Fittings 1.5 Jointing • Locate the outer tension clamp into the groove around the socket end of the pipe to be welded and tighten one of the Allen bolts on the clamp bracket, just enough to hold it in place.
