Description

ASME B16.5 Lapped Flange, Lap Joint Flange, Loose Plate Flange, EN 1092-1 Type 02 Loose plate flange with weld ring neck, EN 1092-1 Type 04 Loose plate flange with weld-neck collar, Gost 12822-80 Loose Flange with Welded Ring

Estan pipe fittings is a premier Lap Joint Flange manufacturer and supplier in China. Based on different materials, our lap joint flange can be sorted into carbon steel, stainless steel, alloy steel, high-strength steel, low-temperature steel, etc.

Lap Joint Flanges have all the same common dimensions as any other flange named on this page however it does not have a raised face, they are used in conjunction with a “Lap Joint Stub End”.

A Stub End always will be used with a Lap Joint flange, as a backing flange in ASME B16.5 NORM. Stub Ends are available in almost all pipe diameters. Dimensions and dimensional tolerances are defined in the ASME B.16.9 standard. Light-weight corrosion-resistant Stub Ends (fittings) are defined in MSS SP43.
