Destructive Tensile Testing is an essential means of ascertaining the integrity of HDPE butt fusion welds on underground water-mains or gas-mains. The welding of the water-main or gas-main is an essential part of adjoining the piping systems. Generally, in Ireland and UK water-mains and gas-mains are laid under the ground. HDPE Piping sections are delivered in 6m lengths and joined together by means of onsite welding.
The characteristics of this weld are fundamental in determining the strength characteristics of the weld and understanding how this adjoined section will perform under pressure and in possibly high stress environments. Welded joints are potential hotspots of weakness in a plastic structure. Consequently, it is important to be able to indicate that a welded joint is fit for purpose and properly tested.
This can be achieved by destructive tensile testing of a welded sample in a controlled laboratory environment.The business will provide a laboratory service where welded samples of HDPE piping can be tested and analyzed.
These welds will be tested used specialist tensile testing equipment. The facility will be capable of testing a variety of HDPE pipe sizes ranging from 90mm to 1000mm diameter and possibly larger should it be required. The test results include visual inspections, stress and strain analyses, extension monitoring under tension, and failure mode analysis with pass or fail reports been provided to the customer. The testing is necessary to allow the contractor to commence the pipe laying process and also monitor the workman ship of the welding crew on site.
The testing of HDPE welds will be the core of our business; however we also expect to expand our business further into other areas to offer a variety of testing options to the private and public sector. Our facility will offer bespoke testing when required.
