Product Details

Stub End Specifications

Size: 1/2" - 56"
Schedule: SCH5 - SCH160/XXS
Standard: MSS SP 43/ ANSI B16.9
Material: Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel

A Stub End always will be used with a Lap Joint flange, as a backing flange. This flange connections are applied in low-pressure and non-critical applications, serving as a cost-effective flanging method. For instance, in stainless steel pipe systems, carbon steel flanges can be used as they do not contact the medium.
