Stainless steel elbow manufacturer quality inspect

Stainless steel elbow manufacturer quality inspection of products  

Stainless steel elbow manufacturers have made an analysis of the quality testing of stainless steel elbow fittings: non-destructive testing of stainless steel elbow fittings:Detect inclusions, pores, cracks and other welding defects.  X - ray, ultrasound and magnetic tests are commonly used now.  X-ray flaw detection is the use of rounded X-ray photography, based on the negative image to determine whether there are defects.

Then according to the technical requirements of the product to evaluate whether the welding is qualified.  The basic principle of ultrasonic inspection is that the detector sends ultrasonic inspection to the metal.  When the ultrasonic waves travel to the interface between metal and air, they are refracted and passed through welding.

When the welding is defective, the ultrasonic wave is reflected and received by the detector, and the reflected wave appears on the screen.  The size and location of the defect can be determined by comparing these reflected and normal waves.  Ultrasound is simpler and more widely used than X-ray.

However, ultrasonic inspection can only be judged according to operating experience, not as the basis of inspection.  Magnetic force can also be used to detect internal defects and small cracks on welded surfaces.

When customers order stainless steel elbow pipe fittings, they mainly see the appearance of stainless steel elbow pipe fittings. Our company provides customers with various testing standards.  For example, the surface, interior, diameter and wall thickness of stainless steel elbow pipe fittings.  Stainless steel elbow pipe fittings in the above quality testing, transport to the hands of customers to obtain customer satisfaction.
