Before the stainless steel seamless pipe is delivered to the customer, we usually conduct a series of inspections on the steel pipe, and only products that pass the inspection can leave the factory.
The complete and standardized inspection is not only to protect the interests of our customers, but also so that we can win the trust of our customers with our quality.
Stainless steel seamless pipe general inspection
●Seamless stainless steel pipe wall thickness inspection
Micrometer is the main tool that is adopted. When you check, left hand holds the micrometer stand, with right hand rotation induced wheel, and the wire rod should be coincident with the diameter of the measuring point.
●Outside diameter, ellipse of seamless stainless steel pipe inspection
Calipers, vernier caliper should be taken. The caliper should be perpendicular to the axis of the steel pipe in checking, measuring the maximum and the minimum point when the pipe rotated slowly.
●Seamless stainless steel pipe length inspection
Can be measured directly by metallic tape.
●Bending inspection of seamless stainless steel pipes
With the tools of level, feeler and line.
●Seamless stainless steel pipes End profile inspection
At two ends of the steel pipe should be cut into specified angle and remove burrs. The method of inspection adopts angle square.
Non-destructive testing of Stainless steel seamless pipe
Nondestructive Testing, shorted for NDT, is a widely-used method in pipeline inspection.
It is a process of testing, inspecting and evaluating the quality and characteristics of the material without damaging the pipeline itself or affecting the later regular work of the pipe. In other words, after NDT testing, the part can still be put into practical use. NDT utilizes the changes in heat, sound and magnets caused by abnormal inner structure or flaws to inspect the internal and external defects of the material.
The common inspection methods of NDT are visual testing (VT), ultrasonic testing (UT), radiographic testing (RT), hydrostatic testing. SMLSCO will provide more details about non-destructive testing in the next sharing.
Mechanical property testing of Stainless steel seamless pipe
Mechanical property test includes tensile strength, yield strength, elongation, impact energy and so on. Process performance test includes flattening test, flaring test, hydrostatic testing, curling trials, cold bend test, perforation test. These test items are designed to verify that the mechanical properties of the seamless steel pipe meet the requirements of the standard.
SMLSCO's inventory of seamless pipes are shipped from the factory after passing an inspection process.
Over the 15 years, we have accumulated certain capital and customer information, and we understand that now customers need us to provide more competitive seamless pipes in the current fierce market competition.
SMLSCO was established to solve the challenges faced by our global customers in terms of price and delivery time, which are the two main aspects.
2000 tons ready stock, if you have any need,feel free to let us know!SMLSCO Looks forward to cooperating with you！
