Metallic Gaskets

Introduction

Origin and application

The sealing of well-head valves and fittingsin exploration and production areas of theoil and natural gas industry has constantly presented a higher pressure requirement than has been necessary in most other major manufacturing processes.To meet this requirement, the AmericanPetroleum Institute developed ring joint flanges and their accompanying gasketrequirement and issued standards covering“general use” and “oil field use”. These two categories are now covered by ASME and API standards respectively, of similar dimension but differently rated in material strength to allow the API flange to operate at a higher working pressure.The solid metal gasket provides an excellentmechanical joint and has almost universal acceptance in the oil, petroleum and chemical processing industries where high mechanical and thermal performance is required.

Top performanceunder extreme conditions

James Walker Moorflex’s precisionmachining creates a product with the highperformance standards needed for today’sextremely demanding applications. Moorflex use only the best forged metals, no weldedrings, which undergo a stringent machiningprocess to ensure that close tolerances andsmooth contact surfaces are rigidlymaintained.Quality is guaranteed by a strict series oftests and process quality control, andMoorflex’s final inspection assures total compliance with customer specifications.Hence, engineers confidently continue tospecify Moorflex gaskets for theirrequirements in both original equipmentand replacements.

Typical uses

?High pressure oil field drilling andproduction equipment.?Pressure vessels.?Pipeline valves.?Gas and chemical plants. Under their Moorside
™ brand James WalkerMoorflex are leading manufacturers of the complete range of solid metal ring joint gaskets. The gaskets are manufactured toAPI 6A, ASME B16 20 and BS7076 Pt 2standards and to customers’ own specifications. 29
