Pipeline steel fittings yog qhov tseem ceeb rau kev sib txuas, hloov pauv, hloov txoj kab uas hla, thiab cov ceg ntev ntev -cov roj / roj, petrochemical, thiab lub zog kav dej, feem ntau yog ua los ntawm API 5L qib pipeline steel los yog cov qib forging / vuam, nrog cov kev cai nruj rau lub zog, toughness, weldability, thiab HIC.
Hom
Lub luj tshib (45 degree, 90 degree, 180 degree): Hloov cov kav dej; Ntev/luv vojvoog xaiv (xws li, LR 1.5D, SR 1.0D).
Tees (Sib npaug / Txo): Tsim cov ceg sib txuas; txo tees txuas cov yeeb nkab sib txawv.
Reducers (Concentric / Eccentric): Kev hloov pauv ntawm cov kav dej sib txawv; eccentric zam cov kua / roj tsub zuj zuj.
Caps / End Caps: Kaw qhov kawg ntawm lub raj xa dej.
Khoov (3D / 5D / 6D): Ntev - vojvoog, kub- tsim khoov rau loj - txoj kab uas hla, txo cov dej tsis kam.
Flanges, Weldolets, Stub Ends: Rau kev sib txuas bolted, ceg ntoo, lossis kev sib koom ua ke tshwj xeeb.
Khoom siv & Qib
Carbon/Low Alloy Pipeline Steel (feem ntau): API 5L (X42/X52/X60/X65/X70, PSL1/PSL2); ASTM A234 WPB/WPC, A420 WPL6, A{11}} qib WPHY; TMCP (Thermo{12}}Cov Txheej Txheem Kev Tswj Xyuas Txheej Txheem) kom muaj zog toughness.
Alloy/High Performance: Rau kev pabcuam qaub (H₂S/CO₂) nrog kev tiv thaiv -sulfide stress cracking (SSC) thiab hydrogen-induced cracking (HIC) zog; dual-theem steel rau qhov chaw huab cua.
Cov qauv: API 5L, ASME B16.9 (lub taub qab-weld fittings), ASME B16.5 (flanges), ISO 15590, DIN 2605.
Txoj kev sib txuas
Butt Welding (BW): Mainstream rau siab -siab ntev- cov kav xa dej, yuav tsum tau kuaj xyuas hluav taws xob (RT) ntawm welds.
Socket Weld (SW)/Threaded (NPT): Rau me me -bore, qis-rau- nruab nrab siab tshuab.
Flanged Connection: Ib qho yooj yim disassembly, haum rau li qub thiab khoom siv interfaces.
