I-China Sch40 A53 A106 API 5L Engenamthungo futhi Eshiselwe Ipayipi Lensimbi Lekhabhoni
Uhlolojikelele
Esikuphishekelayo kwaphakade isimo sengqondo "sokubheka imakethe, bheka isiko, bheka isayensi" kanye nethiyori "yekhwalithi eyisisekelo, nokholo ekuqaleni kanye nokuphatha okuthuthukisiwe" kwePipe Yensimbi Engenamthungo kanye Neshiselwe Ikhabhoni, Ngendlela kokuzikhandla kwethu ukwenza umsebenzi, ngokuvamile siye sathenjwa yikhasimende lethu lemikhiqizo yamapayipi ensimbi.Xhumana nathi namuhla ukuze uthole imininingwane eyengeziwe!Ithimba lethu lizazi kahle izimfuno zemakethe emazweni ahlukene, futhi liyakwazi ukuhlinzeka ngempahla esezingeni elifanele ngamanani angcono kakhulu ezimakethe ezahlukene.Inkampani yethu isivele isungule uchwepheshe, ithimba elihlakaniphile nelinomthwalo wemfanelo ukuthuthukisa amakhasimende ngomgomo wokunqoba okuningi.
Isicelo
Isetshenziselwa Ikakhulukazi izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.

A Isamba salezi zakhi ezinhlanu akufanele sibe ngaphezu kuka-1.00%.
B Kulokho kwehla ngo-0.01% kokuqukethwe okuphezulu kwekhabhoni, okuqukethwe okuphezulu kwe-manganese kuvunyelwe ukukhuphuka ngo-0.06%, kodwa umkhawulo awukwazi ukudlula u-1.35%.
C Ukwehla ngakunye ngo-0.01% kokuqukethwe okuphezulu kwekhabhoni kuzovumela okuqukethwe okuphezulu kwe-manganese ukuthi kukhuphuke ngo-0.06%, kodwa umkhawulo akumele udlule u-1.65%.

A Ubude obuncane begeji engu-2in.(50mm) izonqunywa ngefomula elandelayo:
e=625000(1940)A0.2/U0.9
e = ubude obuncane begeji engu-2in.(50mm), iphesenti lifinyezwa ku-0.5% eseduze;
A = Ibalwa ngokuhambisana nobubanzi obushiwo bangaphandle beshubhu lokuzisholo noma ububanzi obuncane besampula eqinile kanye nogqinsi olucacisiwe lodonga, futhi lazungezwa endaweni eseduze yesigaba esiphambanayo yesampula eqinile engu-0.01 in.2 (1 mm2), futhi Iqhathaniswa no-0.75in.2 (500mm2), kuye ngokuthi yikuphi okuncane.
U = amandla amancane aqinile abekiwe, i-psi (MPa).
B Ngokuhlanganiswa okuhlukahlukene kosayizi abahlukene bezibonelo zokuhlolwa kwe-tensile namandla anqunyiwe abekiwe, ubude obuncane obudingekayo buboniswa kuThebula X4.1 noma kuThebula X4.2, ngokuya ngokusebenza kwakho.
Isidingo Sokuhlola
Ukuhlolwa kwe-tensile, ukuhlolwa kokugoba, ukuhlolwa kwe-hydrostatic, ukuhlolwa kukagesi okungonakalisi kwama-welds.
Ikhono Lokuhlinzeka
Ikhono Lokuhlinzeka: Amathani angu-2000 Ngenyanga Ngebanga ngalinye le-ASTM A53/A53M-2012 Ipayipi Lensimbi
