Uhlolojikelele

Inkampani isekela ifilosofi ethi "Yiba ngohamba phambili mayelana nesisombululo sepayipi", sizoqhubeka nokusebenzela amakhasimende angaphambili namasha asekhaya naphesheya kwezilwandle ngokushisa. Ngepayipi le-carbon steel elishiselwe noma elingenamthungo elilandela izinga le-ASTM A53, sinesipiliyoni seminyaka engaphezu kwengu-30 sokuthenga nokudayisa, esingaqinisekisa ukuthi sinamandla okuqinisekisa ikhwalithi ephezulu yepayipi ngalinye.

Mayelana nepayipi elingenamthungo, kukhona ipayipi lomgunyathi elingenamthungo elikhona, okuyipayipi lemishini eliphansi kunepayipi elingenamthungo, ngoba lenziwe ngepayipi le-ERW, ngemuva kwenqubo, ulayini wokushisela washintsha wacishe wangabonakali. Leli payipi elinomusa alikwazi ukubekezelela ukucindezela okuphezulu, namandla aqinile, ukucindezeleka kwangaphakathi konke akukwazi ukuhlangabezana nezimfuneko mayelana nepayipi elingenamthungo. Uma uxuba le pipe yohlobo olubili, sicela uqaphele ukuthi ipayipi le-ERW lonke lenziwe ngamapheshana ensimbi, ngakho linodonga olufana kakhulu; ipayipi elingenamthungo lenziwa ngebha eyindilinga, libhoboze phakathi nendawo yebha eyindilinga ukwenza amapayipi, ngakho ukushuba kodonga akufani. Futhi umugqa wokushisela wepayipi lomgunyathi womgunyathi usekhona, uma uhlola ngokucophelela ipayipi langaphakathi, ungawuthola.

Isetshenziselwa Ikakhulukazi izingxenye zamandla nengcindezi, futhi ngenjongo evamile yamapayipi omusi, amanzi, igesi nomoya.

Ingxenye Yekhemikhali

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 angeke udlule u-1.35%.

C Ukwehla ngakunye ngo-0.01% kokuqukethwe kwekhabhoni ephezulu kuzovumela okuqukethwe okuphezulu kwe-manganese ukuthi kukhuphuke ngo-0.06%, kodwa umkhawulo akumele udlule u-1.65%.

Impahla Mechanical

A Ubude obuncane begeji engu-2in. (50mm) izonqunywa ngefomula elandelayo:

e=625000(1940)A^0.2/U^0.9

e = ubude obuncane begeji engu-2in. (50mm), iphesenti lifinyezwa ku-0.5% eseduze;

A = Ibalwa ngokuhambisana nobubanzi obushiwo bangaphandle beshubhu lokuzisholo noma ububanzi besampula obuqinile 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.
