180° carbon steel pipe elbow manufacturing process

Aug. 05, 2026

The most common manufacturing process for carbon steel pipe bends is hot forming. Hot forming is divided into two types: hot push bending and hot heating bending. Our 180° carbon steel pipe bends are manufactured using the hot push process. The process flow diagram is shown below.

Pipe fittings are a general term for components in a piping system used for connection, control, direction change, flow diversion, sealing, and support. Steel pipe fittings belong to pressure piping accessories. Based on the processing technology, pipe fittings can be divided into four categories: butt-welded fittings (both welded and seamless types), socket-welded fittings, threaded fittings, and flanged fittings. Fittings that can change the direction of a pipe are called elbows. The function of a 180° carbon steel elbow is to connect two parallel pipes.

What are the advantages of using sliding flanges?

A sliding flange is a type of slip-on flange. Slip-on welding involves welding only the outer layer, not the inner layer. Slip-on flanges are typically used for medium- and low-pressure pipelines with a nominal pressure less than 2.5 MPa. There are four types of sealing faces for slip-on flanges: flat face, raised face (RF), FM/M, and tongue and groove (TG). Flat face is the most widely used and the cheapest. A sliding flange is a slip-on flange with a short neck. Carbon steel sliding flanges, or SO flanges, are generally cheaper than welded neck flanges, which is why customers often choose sliding flanges. As the name suggests, a sliding flange fits over a

Comparison of 180° and 90° Carbon Steel Elbows

Today, I will introduce one of our most popular products by comparing 180° carbon steel elbows with 90° elbows. When two pipe sections are parallel but not aligned, using a single 180° carbon steel elbow is more efficient than welding together two 90° elbows.
