Butt Weld Cross

Butt Weld Cross is a fitting that connects four pipes together at 90-degree angles, forming a cross shape. The term "butt weld" indicates that it is designed for butt welding, which means the pipes are joined end-to-end by welding.

What is Butt Weld Cross？

A Butt Weld Cross is a type of pipe fitting used in piping systems to connect four pipes at a right angle (90 degrees). It is designed to allow fluid or gas to flow in four directions, making it a crucial component in complex piping networks. The term "butt weld" refers to the method of joining the fitting to the pipes, where the ends of the pipes are aligned and welded together.

Types of Butt Weld Cross

Type	Description	Application
Equal Socket Weld Cross	All four socket openings are of the same size.	Systems requiring uniform flow distribution.
Reducing Socket Weld Cross	Socket openings have different sizes, allowing connection of pipes with varying diameters.	Systems requiring flow distribution or merging from pipes of different sizes.
Concentric Socket Weld Cross	The centerlines of all four openings are concentrically aligned.	Systems requiring precise alignment and smooth flow transition.
Eccentric Socket Weld Cross	The centerlines of the openings are offset, creating an eccentric alignment.	Systems requiring fluid drainage or air removal.
Full Coupling Socket Weld Cross	Features full coupling sockets on all four ends, providing a larger welding surface.	High-pressure and high-temperature applications.
Half Coupling Socket Weld Cross	Features half coupling sockets on all four ends, providing a smaller welding surface.	Low-pressure systems and smaller pipe sizes.
Material Classification
Material	Characteristics	Applicable Scenarios
Stainless Steel	Corrosion-resistant and high strength.	Corrosive environments and high-strength requirements.
Carbon Steel	General-purpose material.	General applications.
Alloy Steel	High-temperature and high-pressure resistance.	High-temperature and high-pressure environments.
Duplex and Super Duplex Stainless Steel	Resistant to extreme corrosion.	Extreme corrosive environments.

Features of Butt Weld Cross

Configuration: It has four openings, each at a 90-degree angle to the others, allowing for the connection of four pipes in a cross pattern.

Material: Typically made from materials like carbon steel, stainless steel, or other metals, depending on the application and environment.

Welding: Designed for butt welding, which provides a strong and seamless connection between pipes. This method involves welding the ends of the pipes directly to the fitting.
