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, an MDPE backing band will be installed to protect the rubber from compression damage from the hard shoulders of the pipeline joint. |

Installation : The two stainless steel retaining rings are loosely fitted in position and seal's position is adjusted.
Both stainless steel rings are hydraulically expanded and secured with stainless steel wedges. |

Testing : After the AMEX-10 seal has been installed it is checked and pressure tested to ensure the seal is air tight.
This is done by inflating the seal with compressed air through its integral test valve.
The seal is inflated and a soap test applied.
On pressurised pipelines, the AMEX-10 seal is left to relax and re-expanded after 12 hours.
