Trim the pipe ends all the way around Clean the heater plates When clamping the pipes in place, use the clamps to re-round the pipes Correct procedure: Ask for evidence of recent, random weld inspections by your supervisors Pressure Measure the drag pressure Check the right fusion pressure Add the two together for the overall …
The coupling or the installation? This checklist will help you determine the root cause of a failed coupling. Proper fitting: Is it centralised on the pipe? Accurate installation: Look for evidence of witness marking Accurate installation: Check the angle of each pipe (they should be square to the coupling) Correct procedure: Spot check weld crews. …

Keep your pipeline projects on track When managing a piping project, staying on top of potential risks and inefficiencies can feel like herding cats. You may find yourself constantly reacting to issues rather than preventing them. But what if you had a system to help you predict problems before they arise? That’s where leading and …
When considering performance fittings for piping systems, the suitability and type of bend used on a project is essential to its functionality. In this article we consider bends that are of high-performance for slurries and media applications, and the quality required for a high-performance sweeping bend. How to get the best performance on bends-Best …
When welded and joined correctly,poly pipes are the most leak-proof piping system on the market, according to industry expert Darren. For the past 10, Darren had been imparting his expert knowledge to the next generation of welders through poly pipe welding training. Throughout his career, Darren has seen the impact of failed welds – major …
Polyethylene pipe and fittings are generally very resistant to a variety of chemicals, making them suitable for use in a wide range of chemical processes. However, even with its excellent chemical resistance, it is still important to know how the pipe may be affected. Factors such as the chemical, concentration of the chemical, temperature, duration …
It’s physics 101: materials expand when heated and contract when cooled. High-density polyethylene (HDPE) pipes are not immune to this phenomenon. HDPE pipes expand and contract when the pipe temperature changes from the installation condition to the operating condition. When a pipe expands, it can generate enormous force and stress in the system, but, if …
Are you wondering what Poly Pipe is? If you are involved in civil infrastructure, mining, or utilities, you’ve likely heard the term “poly”, but what exactly is it, and why has it become the industry standard over traditional materials like steel or PVC? Also known as High-Density Polyethylene (HDPE) or simply PE, it is a …
PE100 pipes can last more than 50 or 100 years. Quality extrusion welds can match that, but poor welds can be the first thing to break. Here’s a quick look at the main steps to go through, and common problems to avoid, next time you handle an extrusion welder. The materials and technology that go …
Poly pipe electrofusion welders are often needed to fit, join, or fabricate poly pipe on-site. Welders are most often used by maintenance crews on large scale jobs such as: water treatment plants chemical process plants; and commercial irrigation systems. They can also be used on civil projects such as: water pipelines or renewals; or fire …
