A Socket Weld Cross is a type of pipe fitting used in plumbing and industrial piping systems. Unlike butt weld fittings, socket weld fittings are designed to be inserted into a socket and then welded in place.
A Socket Weld Cross is a type of pipe fitting used in piping systems to connect four pipes at a right angle (90 degrees). Unlike a Butt Weld Cross, which is welded directly to the pipes, a Socket Weld Cross has socket-like openings that allow pipes to be inserted into the fitting before being welded. This design is particularly useful for smaller pipe sizes and high-pressure applications.
Type | Characteristics | Applications |
Carbon Steel Butt Weld Cross | Strong and durable, suitable for high-pressure applications. | Industrial piping systems, oil and gas pipelines. |
Stainless Steel Butt Weld Cross | Corrosion-resistant, suitable for environments with moisture or chemicals. | Food processing, pharmaceuticals, marine industries. |
Aluminum Butt Weld Cross | Lightweight and corrosion-resistant, suitable for weight-sensitive applications. | Aircraft, automotive industries. |
Brass Butt Weld Cross | Corrosion-resistant, suitable for low-pressure applications. | Residential plumbing, irrigation systems. |
Small Diameter Butt Weld Cross | Suitable for smaller pipes (e.g., 1/2 inch to 2 inches). | Residential plumbing, HVAC systems. |
Large Diameter Butt Weld Cross | Suitable for larger pipes (e.g., 4 inches and above). | Industrial and commercial applications. |
Low-Pressure Butt Weld Cross | Designed for low-pressure applications. | Residential plumbing, irrigation systems. |
High-Pressure Butt Weld Cross | Stronger materials, suitable for high-pressure applications. | Industrial applications, oil and gas pipelines. |
Low-Temperature Butt Weld Cross | Suitable for low-temperature applications. | Refrigeration systems, cryogenic applications. |
High-Temperature Butt Weld Cross | Made from materials like stainless steel, suitable for high-temperature applications. | Industrial furnaces, power plants. |
Smooth Finish Butt Weld Cross | Provides a smooth surface, reducing corrosion and ensuring clean flow. | Food processing, pharmaceuticals. |
Rough Finish Butt Weld Cross | Suitable for applications where a smooth finish is not critical. | Industrial applications where cost is a major factor. |
Threaded Butt Weld Cross | Features threaded connections instead of welded joints. | Applications where threaded connections are preferred. |
Flanged Butt Weld Cross | Features flanged connections, providing a strong and secure connection. |
