ASME B16.47 Loose Lap Joint Flanges Manufacturers and Suppliers:
A Lap Joint Flange is a type of flange that is used to connect two pipes or fittings together. The flange itself is comprised of two parts: the flange ring, which is usually made of carbon steel, and the stub end, which is made of a material that is compatible with the pipe or fitting being joined. The flange ring has bolt holes around its perimeter, which are used to bolt it to another flange or to a piece of equipment.

ADCO Forge and Fittings is a renowned manufacturer of lap joint flanges, among other types of flanges and fittings. we use advanced manufacturing processes to ensure high-quality products that meet or exceed industry standards. offers lap joint flanges in a variety of materials, including carbon steel, stainless steel, and alloy steel, to meet the needs of a wide range of applications. our commitment to customer satisfaction and attention to detail has earned a reputation as a trusted supplier in the industry.
The dimensions of lap joint flanges are standardized by organizations such as ASME B16.5 and ASME B16.47. Lap joint flanges are available in various classes, including class 150, class 300, and class 600, which specify the pressure ratings of the flange.
There are also international standards for lap joint flanges, such as DIN 2642 and EN 1092-1. These standards specify the dimensions of the flange and the materials to be used.
Lap joint flanges can be used with either a flat face or raised face, depending on the application. A gasket is typically used between the flange faces to create a seal. The most common gasket materials for lap joint flanges are compressed non-asbestos, graphite, and PTFE.
Lap joint flanges are available in a variety of international standards, including JIS 10K, PN16, and PN10. They can also be used with ring type joint (RTJ) gaskets for high pressure applications.
We have the ready inventory of Lap Joint Flanges in the different size ranges of 2 Inch, 3 Inch,, 6 Inch Class 150, 8 Inch Class 150 Lap Joint Flange.
