After the seamless steel pipe is finished, it is sent to the inspection department for product quality inspection, which is an important measure to ensure the quality of the seamless steel pipe from the factory. The inspection standards and content are stipulated by national standards and some standards or technical conditions. 　

Seamless steel pipe inspection can be spot check and all. Sampling inspection is generally to determine the mechanical properties, internal organization and chemical composition of seamless steel pipes. In addition to sampling inspections in a batch of seamless steel pipes, seamless steel pipes for some important uses are sometimes subject to all inspections. In addition, hot-rolled seamless steel pipes are subject to process tests such as flattening, bending, crimping, and flaring, as well as hydraulic tests according to standard requirements.
