How it works

The success of the AMEX-10 seal lies in its simplicity. Made from EPDM and stainless steel, the system works by providing a new water tight seal over the leaking joint. The step-by-step process below shows how the system is installed.


				Survey : The pipeline joints are surveyed for condition and suitability by PMP’s experienced surveyors and the internal diameter is accurately measured. The client is provided with a fixed price quotation for the assessed number of AMEX-10 seals. If not in stock, the seals are ordered and made-to-measure. When the new seals arrive, PMP inspect and prepare the seals ready for installation.

				Surface Prep : AMEX-10 fitters will check and clean the leaking joints to remove dirt and corrosion. If the pipe surface is not smooth, imperfections will be removed by flap disc abrasion to make the pipe wall smooth ready for the AMEX-10 seal.

				Installation : For pressurised pipelines only, a polypropylene backing band will be installed to protect the seal rubber from compression damage from the hard shoulders of the pipeline joint.

				Installation : Two stainless steel retaining rings are placed in position and the seal's position is adjusted. Both stainless steel rings are expanded hydraulically and secured with stainless steel wedges.

				Testing : The seal is thoroughly checked and pressure tested. The seal is inflated by compressed air through its integral test valve and a soap test carried. On pressurised pipelines, the AMEX-10 seal is left to relax and re-expanded after 12 hours.
