Importance of non-destructive testing in pipe fitting production
Non-destructive testing is used to identify defects that may occur in materials or processing. The non-destructive testing requirements specified in different standards are inconsistent, and common methods include:
• Ultrasonic testing
• Radiographic testing
• Magnetic particle testing
• Penetrant testing
Manufacturers will also add testing steps based on internal quality control standards or customer requirements to ensure that the product meets the standards. Testing qualifications should be determined based on orders or relevant standards.

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. Schxx represents the wall thickness grade; 180e (S) indicates a short-radius 180° carbon steel elbow, and 180e (L) indicates a long-radius 180° elbow; 90E (S) indicates a short-radius 90° carbon steel elbow, and 90e (L) indicates a long-radius 90° elbow; 45

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
