Carbon steel butt-welding pipe fitting

What is carbon steel butt-welding pipe fitting?

Carbon steel buttweld pipe fitting is a vital component of piping systems used in various industrial applications.It is commonly used for connecting, redirecting or branching pipelines while ensuring a safe leak-free connection. Most importantly, duo to its superior durability, strength and economy, it is used in a wide range of applications, such as construction, oil, and gas industries.

Butt-welded pipe fittings are so named because they are welded to the pipe through a butt-welding process. This involves welding the fittings to the ends of the pipeline, creating a smooth, continuous connection without any protrusions or gaps that could cause turbulence or leakage of the fluid or gas being transported. Furthermore, carbon steel butt weld fittings come in a variety of shapes, sizes and types, each of which has a specific use in piping systems.

Introduction

Elbow:

Carbon steel elbow is mainly used to connect and redirect pipelines. Owing to its good comprehensive performance, it is widely used in chemical industry, construction, water conservancy, natural gas, petroleum, electric power, aerospace, shipbuilding and other basic engineering.

Including Long radius elbow, Short radius elbow, 90 degree elbow, 45 degree elbow, 60 degree elbow, 180 degree elbow, Reducing elbow.

Tee:

A pipe tee is a kind of pipe fitting and pipe connector with three openings, which usually used at the convergence of three identical or different pipelines to change the direction of the fluid.

Including equal tee(with the same diameter at three ends) and reducing tee(the branch pipe is different in diameter from the other two).

Reducer:

Carbon steel reducer is used for the connection between two pipes with different diameters. Depending on the different shapes, it is divided into two types: Concentric reducer and eccentric reducer. Concentricity is well understood , the circular center points at both ends are in the same straight line called concentric reducer. On the contrary, it is called eccentric reducer.

Cap:

Pipe caps are usually used for protecting the end of pipe and other fittings, so the shape design should be fit the shape of the pipeline and fittings.

Applications of Carbon Steel Butt-welding Fitting

Butt Weld Fittings are pipe fittings used to change the flow direction, branch off, reduce pipe size or attach auxiliary equipment. There are three main applications as follows:

1. Buttweld fittings are used in the structural shapes, construction, automobile, pipelines and bridge components.
2. Owing to excellent strength and wear resistance, they are used in fuel processing, oil and gas processing, chemical equipment, power generation and other applications.
3. They are also used in nuclear power plants, boilers, heat exchangers, oil refineries, etc.
