Stubend

Stub End

A Stub End is essentially a brief length of pipe having one square-cut end and one flared end that is welded to a pipe of the same NPS, material grade, and schedule when used with a backing flange. As an alternative to a normal flange, a Stub End and backing flange combination is frequently utilised. The flange can be made of less expensive carbon steel since it is only the Stub End that must be of the same material grade as the pipe because it is welded to the pipe. Three different types of stub ends are produced.

High-quality, high-performance stub end (lap joint) fittings in all major grades that conform to international dimension standards are among the things we regularly produce and keep in stock. Stub ends are available in both common and uncommon ANSI diameters. Seamless and lap joint (welded) stub ends in stainless steel, carbon steel, alloy steel, and nickel alloy are available from Marcel Piping in a range of heights.

Long Stub end

Concentric reducers from Trimac join tubes and pipes on the same axis. This kind of reducer provides a conical passageway in-line between pressured pipes of various dimensions. A pipe reducer is offered in a variety of specifications, including both single and multiple diameter changes. Despite how the pipe reducer’s external arrangement makes it appear, the internal width conical transition arrangement changes the flow of the pipe. It can be externally rearranged and moved axially to provide more effective reducer connections.

One of the pipe fittings used to joain two pipes with different diameters is the pipe reducer. A pipe reducer is used to alter the flow rate of fluids. Reducers are typically created using reduction pressing, expanding pressing, or a combination of reducing and expanding pressing. For reducers with specific requirements, we can also use stamping procedures. Eccentric and Concentric Reducers are the two different types of reducers. According to the requirements of their applications and industries, pipe reducers are widely available in a variety of materials and also come in a variety of sizes.
