The stainless steel of socket welded pipe fittings is measured or inspected by some physical phenomena. The inspection of workpiece material or internal defects is a non-destructive testing method. So how much do you know about the physical inspection method of stainless steel socket welded pipe fittings?

1. X-ray inspection:

X-ray inspection is a detection method that uses radiopaque materials and the attenuation characteristics of materials to find defects. According to the different rays used in the inspection, it can be divided into X-ray inspection, γ-ray inspection and X-ray inspection.

2. Ultrasonic flaw detection:

When the ultrasonic wave propagates in a homogeneous medium such as metal, due to the reflection on the interface of different media, it can be used for internal defect detection.

3. Penetration testing:

Penetrant testing uses physical properties such as the permeability of certain liquids to find and display defects, including color detection and fluorescent penetrant testing, which can be used to detect magnetic and non-magnetic defects on iron surfaces.

4. Magnetic inspection:

Magnetic flaw detection is to use the magnetic field magnetization of ferromagnetic metal parts to generate magnetic flux leakage to find defects. According to the different methods of measuring magnetic leakage, it can be divided into magnetic powder method, magnetic induction method and magnetic recording method.

The physical inspection methods of stainless steel socket welded pipe fittings are mainly those mentioned above. We can inspect our stainless steel socket welded pipe fittings according to the above inspection methods.

What are the functions of socket welded pipe fittings?

Socket welded pipe fittings are often used to connect cast iron pipes and acid-resistant ceramic pipes, and play an important role and value in the connection process of different pipe fittings. The detailed connection method of socket and socket fittings is to insert a pipe into the casing at the other end, Fill the annular space with hemp rope or asbestos rope, and then insert adhesive (such as cement, acid-resistant cement, etc.) to achieve the purpose of sealing.
