API 5L Qib B Pipe
- API 5L Specification rau Kab Yeeb
Kab yeeb nkab, feem ntau hu ua "steel refrigeration bending profile," yog ib qho hollow, square-section steel yeeb nkab. Nws yog tsim los ntawm square-cross-sectional-size steel los ntawm kub dov los yog txias dov strips los yog coils raws li lub hauv paus khoom los ntawm txias dabtsi yog khoov, ua, thiab tsim, thiab ces high-frequency vuam. Cov yeeb nkab yeeb nkab yog siv rau cov pa roj, dej, thiab roj hloov hauv kev lag luam roj thiab roj, thiab nws los ntawm ob hom: seamless thiab welded yeeb nkab nrog lub tiaj tiaj, threaded kawg, thiab lub qhov (socket) xaus.
Scope
API 5L Specification qhia txog qhov yuav tsum tau ua rau kev tsim khoom ntawm ob theem kev qhia tshwj xeeb (PSL 1 thiab PSL 2) ntawm seamless thiab welded steel yeeb nkab rau kev siv hauv cov kav dej hauv kev thauj mus los hauv kev lag luam roj av thiab cov nkev.
Cov khoom specification qib yog abbreviated li PSL. PSL1 thiab PSL2 yog cov khoom specification qib rau cov kav dej, thaum PSL1 thiab PSL2 yog cov qib zoo. PSL2 siab dua PSL1. Vim tias ob qhov kev qhia tshwj xeeb txawv tsis yog hauv kev tshuaj ntsuam xyuas nkaus xwb tab sis kuj tseem muaj cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab thaum xaj raws li API 5L, cov lus cog lus yuav tsum suav nrog cov khoom lag luam, piv txwv li, PSL1 lossis PSL2, ntxiv rau cov ntsuas ib txwm muaj xws li specification thiab qib steel raws li API 5L, cov lus cog lus yuav tsum suav nrog cov khoom specification, piv txwv li, PSL1 lossis PSL2, ntxiv rau cov ntsuas ib txwm muaj xws li specification thiab qib steel. Hais txog tshuaj lom neeg muaj pes tsawg leeg, tensile zoo, cuam tshuam kev ua haujlwm, tsis muaj kev puas tsuaj, thiab lwm yam, PSL2 yog nruj dua PSL1. PSL1 tsis tas yuav tsum ua cov yam ntxwv cuam tshuam; Txawm li cas los xij, PSL2 yuav tsum ua cov yam ntxwv cuam tshuam rau txhua qib steel tshwj tsis yog X80.
