Annual production and sales and sales agents Cheng Gang, Steel, Bao, saddle, rule of the day, Hengyang Steel and other major steel production plants: 10 # .20 #, 45 #, 16Mn, 27SiMn, Q345B.35CrMo, 20Cr, 40mn2 , 40crmo.20crmnTi 316l stainless steel pipe, 10CrMo910 15crmo 12Cr1MoV 20G, st52, s45c and geology, pipelines, chemical, power and other special pipe stainless steel pipe, are the implementation of national standards:.. GB8162-87, GB8163-87 and GB3087-82, GB5310 -95, GB6479-86; pipe, high pressure boiler seamless steel pipe, oil cracking pipe, imported alloy steel pipe, alloy seamless steel, bearing steel, special welded pipe, spiral pipe, galvanized pipe, stainless steel tube inside the boiler now thread tube is not divided into non-thread sealing and thread sealing, now divided into three criteria: column / pillar with the column / cone fit and taper / taper fit. Pillar / column with: no sealing capability can be added sealing structure for low static load. Column / Cone with: sealing capability, used in low-voltage static load, such as water, gas pipes. Cone / cone with: more difficult to complete a full cone seal, often already screwed tight 310s stainless steel pipe, but still there is a leak. But once a seal will not easily be destroyed, for high-pressure dynamic loading. 55 degrees sealing pipe thread - internal Taper internal and external threads sealed low probability, but can not easily be destroyed, can be used for high voltage withstand shock loads of occasions. GB / T 7306.2-2000 55 degrees unsealed pipe thread - the inner cylindrical threaded cylindrical outer thread does not have after its internal and external thread with tightness in the piping system only play the role of a mechanical connection stainless steel pipe fittings, seals may aid in end face seal thread deputy outside, used for low pressure pipeline system under static load.
