Carbon materials are high-pressure boiler pipe GB5310-2008: 20G, 20MG, 25MG, 15MoG, 20MoG; GB6479-2000 fertilizer tube materials are: 10,20G, Q345, Q390,10MoVNb, 12CrMo, 15CrMo, 12Cr2Mo; petroleum cracking tube GB9948-2006 materials are: 10,20,12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo; the company to provide users with a variety of special specifications, special materials seamless, timely delivery, low price, excellent quality, with a book or a copy of the original material pieces of high-pressure boiler tube manufacturers, holiday business as usual, and agents Automotive, fire operation can accept settlement. Now is not within the boiler tubes threaded into a 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 add high-pressure boiler pipe sealing structure prices for low static load. Column / Cone with: sealing capability, used in low-voltage static load, such as water, gas pipes. Cone / cone with: complete the entire cone seal more difficult high-pressure boiler tubes, often already screwed tight, 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 the seal after its internal and external thread with, only play the role of mechanical connections in the piping system, can make use of seals in the thread deputy beyond the end face seal, used for low pressure pipeline system under static load.
