After purchasing the seamless pipe business, will conduct the evaluation, in order to ensure the quality of seamless steel tubes, you can select the sample tube to a regular inspection thick-walled seamless steel pipe, seamless steel pipe to determine whether there is a bubble, turn leather case, while 20 # seamless steel pipe, and see if there are residues from the sample, which will affect the seamless steel parts are good or bad. Meanwhile 20cr thick-walled seamless, professional and technical personnel may also measure the overall length of the pipeline, we are often used calipers, vernier caliper to measure by. Seamless steel as the main material of the thick-walled seamless pipeline transportation, except for some conventional energy transport, will transport a number of other energy sources, such as some of the high heat of the fluid, or some liquid has a corrosive, Overall, the use of seamless steel pipe is still very large. In the cities, many of the buildings under the water under the same seamless steel pipe is used as the main material. Standing Material: 20 #, 45 #, 20G, 16Mn, 27SiMn, 12Cr1MoVG, 15CrMo, T91,10CrMo910, STFA25 (P5), STFA26 (P9), P11, P12, A335P91, A335P92, WB36 [15NiCuMoNB5], Steel Institute 102 ( 12Cr2MoWVTiB) and so on. Implementation of the standards: Structural pipe GB8162-1999, fluid pipe GB8163-1999, low-pressure boiler pipe GB3087-1999, hydraulic support GB17396-1999, high-pressure boiler tubes GB5310-1995, fertilizer dedicated pipe GB6479-2000, oil cracking pipe GB9948 -88, boating tube, GB5312-2000.
