API 5L Grade B Carbon Steel Pipe Line Pipe

Tlhaloso e Khutšoanyane:

Pipe ea tšepe ea API 5L Kereiti ea B ke phala e tloaelehileng ea phaephe ea lipeipi tsa oli le khase.E boetse e tsejoa e le phala ea L245, e boletsoeng ho ISO 3183, e rehelletsoeng ka matla a bonyane a tlhahiso ea 245 Mpa (355,000 Psi).

Thepa e lekanang le ASTM A106 B kapa ASTM A53 B e nang le boleng bo ts'oanang ho sebopeho sa lik'hemik'hale, thepa ea mochini le ts'ebeliso.

API 5L B e akaretsa PSL1, PSL2, ts'ebeletso e bolila bakeng sa lipeipi tsa lebopong le kantle ho naha.Mefuta e entsoeng ka maiketsetso e kenyelletsa seamless le welded.

Kenyelletso ea Sehlahisoa

PSL1, PSL2 le Mefuta ea Acidic Media.

Hangata ho sebelisoa PSL1, e lekanang le ASTM A106 B le A53 B.

PSL2 ke phala ea boemo bo holimo e nang le litlhoko tse thata bakeng sa matla a lik'hemik'hale le a mochini.PSL2 e hloka mekhoa e mengata ea liteko joalo ka tlhahlobo e sa senyeheng, tlhahlobo ea phello ea CVN, DWT, jj.

API 5L B PSL2 e emetsoe ke API 5L BN/Q/R/M.

Bohareng ba asiti: Bakeng sa liphaephe tsa asiti joalo ka tikoloho ea H2S, thepa ea lipeipi e na le litlhoko tse tloaelehileng bakeng sa likarolo tsa lik'hemik'hale tse joalo ka khabone, phosphorus le sebabole.Reference standard ea NACE MR0175.

Suffix Lengolo

Maletere a suffix a hlalosa maemo a phaephe ea thomello:

R: Ha o bilika.

N: normalizing rolling, normalizing forming, normalizing.

P: Ho ikoetlisa le ho ikoetlisa.

M: Thermomechanical rolling kapa thermomechanical forming.

S: Sour medium le PSL2 tubing bakeng sa NS, QS, MS, mohlala API 5L Grade B NS, API 5L B QS.

Mefuta e sa tsitsang le e cheselitsoeng (RW, LSAW, SSAW/HSAW) mefuta.

Mofuta oa Sehlahisoa

Mofuta oa Seamless:ho kenyeletsoa liphaephe tse se nang moroko tse chesang tse fetang lisenthimithara tse 3, liphaephe tse se nang moroko tse ka tlas'a lisenthimithara tse tharo.

Mofuta oa Welding oa ERW:Resistance Welding, e loketseng liphaephe ho fihla ho lisenthimithara tse 24.

Mofuta oa Welding oa Arc o Otlolohileng oa Seam:Longitudinal segmented arc welding, e loketseng liphaephe tse bophara ba lisenthimithara tse 20 ho isa ho tse 48.LSAW e boetse e tsejoa e le JCOE, e bolelang ho etsa libopeho ho tloha liphaepheng tse nang le sebopeho sa J, sa C, sa O, ebe se atolosoa ka serame.

Mofuta oa SSAW/HSAW:Spiral Submerged Arc Welding kapa Spiral Saw bakeng sa phala e fihlang ho 100" OD.

API 5L Grade B, ASTM A106 Grade B le A53 Grade B, lisebelisoa tsena tse tharo ke lisebelisoa tse sebelisoang haholo kahong ea lipeipi kapa liindasteri tsa oli le khase le lipalangoang tsa metsi.

ASTM 106 Pipe e bua ka peipi ea tšepe e kolobisitsoeng e chesang kapa e huleloang ka mohatsela (e phuthoang) e se nang moroko.

Phaephe ea ASTM A53 e kenyelletsa liphaephe tsa tšepe tse cheselitsoeng le tse se nang seam tsa thepa e ntšo ea k'habone, 'me ka linako tse ling li-galvanized tse chesang (tse nang le galvanized).
