Onye na-ebupụ China Steel Welded Carbon Pipe
MbupụCarbon Steel Pipe,China Steel Pipe,Obere Carbon Steel Pipe,welded ọkpọkọ, si China. Ụlọ ọrụ anyị na-ahụ maka mbupụ nke ọkpọkọ ígwè welded na ọkpọkọ igwe anaghị agba nchara. A na-ebupụ ọtụtụ puku tọn ọkpọkọ ígwè welded kwa afọ. A na-ekewa ọkpọkọ welded nke na-ebupụkarị mbupụ gaa na LSAW na SSAW. Ị maara ọdịiche dị n'etiti LSAW Pipe na SSAW Pipe?
Ọkụ LSAW (Ọdụdọ Arc- Welding Pipe), nke a na-akpọkwa SAWL ọkpọkọ. Ọ na-ewere efere ígwè dị ka akụrụngwa, jiri igwe na-akpụzi ya na-akpụzi ya, wee mee ịgbado ọkụ n'okpuru mmiri nwere akụkụ abụọ. Site na usoro a, ọkpọkọ ígwè LSAW ga-enweta ezigbo ductility, weld toughness, uniformity, plasticity and great sealing.
Ogologo dayameta ọkpọkọ LSAW buru ibu karịa ERW, na-adịkarị site na inch 16 ruo 60, 406mm ruo 1500mm. Ịrụ ọrụ dị mma na nguzogide nrụgide dị elu, yana nkwụsị nke corrosion dị ala.
A na-etinye ya n'ọtụtụ ebe na pipeline mmanụ na gas, nke a chọrọ n'ụzọ pụrụ iche nnukwu dayameta na nnukwu mgbidi mgbidi na ike dị elu na ogologo anya. Ka ọ dị ugbu a na-ewu ihe owuwu nke chọrọ ike siri ike, ọgwụgwọ mmiri, ụlọ ọrụ thermal, ụlọ akwa mmiri, wdg. Dị ka nkọwa API, a na-ahọpụta ọkpọkọ LSAW (SAWL ma ọ bụ ọkpọkọ JCOE) na nnukwu mmanụ na gas njem, n'ọnọdụ ndị ahụ. pipeline gafee obodo, oké osimiri, na obodo mepere emepe. Ndị a bụ ngalaba 1 na klas 2.
SSAW Pipe (Spiral Submerged Arc-welding Pipe), nke a na-akpọkwa HSAW ọkpọkọ (Helical SAW), ahịrị ịgbado ọkụ dị ka helix. Ọ na-eji otu teknụzụ ịgbado ọkụ nke Submerged Arc-welding nwere ọkpọkọ LSAW. N'ụzọ dị iche iche SSAW ọkpọkọ bụ gburugburu welded ebe LSAW na ogologo welded. Usoro nrụpụta na-atụgharị eriri ígwè ahụ, iji mee ka ntụgharị ntụgharị nwee akụkụ na ntụziaka nke etiti ọkpọkọ, na-emepụta na ịgbado ọkụ, ya mere eriri ịgbado ọkụ dị n'ahịrị okirikiri.
Ihe dị iche iche nke ọkpọkọ SSAW sitere na 20 nke anụ ọhịa ruo 100 inch, 406 mm na 2540 mm. Akụkụ uru bụ na anyị nwere ike ịnweta dayameta dị iche iche nke ọkpọkọ SSAW na nha nha nke eriri ígwè, enwere ngwa ngwa maka akụrụngwa akụrụngwa. ígwè warara, na ịgbado ọkụ onuete kwesịrị izere isi nchegbu, ezi arụmọrụ na-ebu nchegbu.
The mwepu bụ ọjọọ anụ ahụ akụkụ, ịgbado ọkụ onuete ogologo bụ ogologo karịa ọkpọkọ ogologo, mfe ime ka ntụpọ nke cracks, ikuku oghere, cinder nsonye, ele mmadụ anya n'ihu ịgbado ọkụ, ịgbado ọkụ ike na Anam Udeme ọnọdụ.
Maka sistemu pipeline mmanụ na gas, mana na nkọwapụta mmanụ ala, ọkpọkọ SSAW / HSAW nwere ike itinye naanị na klaasị 3 na mpaghara 4. Ihe owuwu ihe owuwu, njem mmiri na ọgwụgwọ nsị, ụlọ ọrụ ọkụ, ụlọ wdg.
