Ikhwalithi ephezulu yase-China Sch40 A53 A106 API 5L Engenamthungo futhi Eshiselwe Ipayipi Lensimbi Lekhabhoni
Uhlolojikelele
"Ubuqotho, Ukuqamba Okusha, Ukuqina, Nokuphumelela" kungaba umbono ophikelelayo wenhlangano yethu, ngaleyo ndlela yesikhathi eside yokuphendulana okufanayo, Njengamanje, igama eliqinile linensimbi ye-carbon steel kanye nemikhiqizo ye-Cr Mo Alloy Steel futhi yazuza irekhodi eliphezulu kanye namasheya amakhulu. emakethe yakuleli naphesheya kwezilwandle.
Okunye ukusetshenziswa kwamapayipi ethu imisebenzi yomlilo, njengokuthuthwa kwamanzi ngomsebenzi womlilo, ukuvikelwa kwezintambo zikagesi zohlelo lokucisha umlilo nokunye.
Sicela uqaphele, amapayipi e-iron ductile, amapayipi ethusi, amapayipi e-alloy, amapayipi ahlanganisiwe, ipayipi yensimbi ye-carbon, njll. ngokuvamile asetshenziselwa amapayipi okulwa nomlilo. Izidingo zosayizi zihlukile kumapayipi enhloso evamile futhi zinezidingo zabo ezikhethekile. Amapayipi okulwa nomlilo ngokuvamile adinga ukupenda ngopende obomvu noma indilinga ebomvu. Ukuyihlukanisa kwamanye amapayipi.
Ekusebenzeni kwangempela, izingxenye ezihlukene zohlelo lokuvikela umlilo zinezidingo ezihlukene zezinhlobo zamapayipi nezinto zokwakha, njengokuthi: amapayipi angaphezulu kumapayipi omlilo angaphakathi, lapho ingcindezi yokusebenza kwesistimu ingaphansi noma ilingana ne-1.20MPa, amapayipi ensimbi adiphu ashisayo. ingasetshenziswa; Uma ingcindezi yokusebenza ingaphezu kuka-1.20MPa, ipayipi lensimbi eliwugqinsi elidiphu elishisayo noma ipayipi lensimbi elingenamthungo elidiphu elishisayo lizosetshenziswa; lapho ingcindezi yokusebenza kwesistimu ingaphezu kuka-1.60MPa, ipayipi lensimbi engenamthungo elishisayo lizosetshenziswa.
Isicelo
Ipayipi lensimbi engenamthungo yokusebenza okuphezulu kokushisa kwe-ASTM A106, efanelekile ukushisa okuphezulu
