The process of forming stamped elbows

Dec. 01, 2025

The process of forming stamped elbows generally involves cutting a circular ring shell into four 90° elbows, six 60° elbows, or other specifications. This process is suitable for manufacturing large elbows of any specification with a ratio of the elbow's mean diameter to its inner diameter greater than 1.5, and is currently the ideal method for manufacturing large pressure-bearing elbows.

Stamped elbows have the best pressure resistance. However, due to various factors, the actual wall thickness of underfloor heating pipes is usually [not specified in the original text]. At this wall thickness, various pipe materials can meet the requirements of underfloor heating, and the pressure resistance advantage of national standard stamped elbow pipes is not fully realized. Thermal conductivity: Pipes used for underfloor heating need good thermal conductivity and good low-temperature impact resistance. No pipe blank is required as raw material, saving on pipe manufacturing equipment and mold costs, and elbows with arbitrarily large diameters and relatively thin walls can be obtained.

The low-temperature welding principle of stamped elbows: Soft brazing and hard brazing are used, with the heat source selected according to different site requirements.

Advantages: Flexible operation, high selectivity, relatively low technical requirements, well-controllable deformation, minimal thermal impact on the base material, and aesthetically pleasing.

Advantages of seamless carbon steel elbows

The raw material for seamless carbon steel elbows is seamless steel pipe. The main production process involves heating and piercing a round tube billet, then rolling it using three-roll cross rolling, continuous rolling, or extrusion to set (or reduce) the outer diameter of the pipe. After cooling, it is straightened. It undergoes direct hydrostatic testing (or flaw detection), is marked, and then stored.

180° carbon steel pipe elbow manufacturing process

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.

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
