Carbon Steel API 5L Qib B PSL2 roj thiab gaspipe

Khoom Taw Qhia

API 5L B Cov Khoom Siv yog dav siv nyob rau hauv kev lag luam kev lag luam rau kev tsim kho lossis kua tsheb thauj khoom. API 5L B Qib Siab Siab- Lub zog Steel Kav muaj nyob hauv ob qho khoom lag luam, PSL1 thiab PSL2, txhua tus nrog nws cov ntawv thov tshwj xeeb. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm API 5L B Qeb Psl2 siab- lub zog steel yeeb cas muab nws tshwj xeeb cov khoom siv neeg kho tshuab. Lub xub ntiag ntawm chromium nyob rau hauv API 5L B Qib Siab Hom Steel Yeeb pab txhim kho nws cov kev coj tsis kam, lub ntsiab lus API 5L B Qeb Psl1 LSAWW STEEL YEES yog heev ruaj. Ib yam li ntawd, lub molybdenum cov ntsiab lus hauv API 5L B Qib Psl2 dsaw steel yeeb nkab muab nws zoo heev} kub nkag.

Parameter rooj

Cov tshuaj lom neeg muaj pes tsawg leeg ntawm Api 5L Welded yeeb nkab tau txwv tsis pub muaj carbon, manghese, phosphorus, thiab leej faj los ua kom zoo heev veldability thiab corrosion tsis kam.

Nto Kho
Lub hom phiaj tseem ceeb ntawm kev kho deg yog tshem tawm cov paug, thiab muab cov yeeb nkab luv los txhim kho thaum lub sijhawm thauj mus los, chaw khaws khoom, thiab kev pabcuam.

1. Sab nraud kho mob:

Kev tu kom txhua hnub: Ua ntej, sab nraud ntawm cov yeeb nkab steel yog ntxuav kom tshem tawm cov roj rho, av, thiab lwm yam impurities uas tuaj yeem cuam tshuam rau kev kho mob tom ntej.

Txhaj tshuaj blasting / tua peening: Qhov no yog qhov tseem ceeb tshaj plaws thiab kev kho mob. Cov yeeb nkab steel tau dhau los ntawm kev txhaj tshuaj blasting tshuab thiab cuam tshuam los ntawm high- ceev dav hlau los yog cov hlau loj.

Lub Hom Phiaj: Txhawm rau kom huv si tshem cov xeb, nplai, thiab cov ntawv xoob ntawm cov nplaim dej.

Txhawm rau tsim cov khaub ncaws hnav, thauj tog rau nkoj {} Txoj kev txawv roughness ntawm {{1} Cov tshuaj pleev corrosion (xws li 3PE, FBE).

Txheem: Feem ntau yuav tsum muaj qib kev nyiam huv ntawm SA 2.5. Qhov no yog ib qho kev lees paub thoob ntiaj teb, lub ntsiab lus "nrov heev blasting." Qhov saum npoo yuav tsum yog qhov tsis muaj roj pom, av, nplai, xeb, thiab lwm yam txawv teb chaws. Cov kab twg uas tseem tshuav yuav tsum tsuas yog ua kom meej me ntsis, xws li cov dots lossis streaks.

2. Sab saum toj kev kho mob: sab hauv kho cov kab sib txawv nyob ntawm daim ntawv thov thiab cov neeg siv khoom yuav tsum tau ua.

Tsis muaj kev cai tshwj xeeb: kev ntxuav kom huv lossis tshuab yooj yim los yuav txaus kom tshem tawm cov vuam vias sab hauv slag thiab hmoov av.

Nrog cov txheej txheej kom zoo: yog tias sab hauv phab ntsa yuav tsum tau ua kom haum rau cov txheej txheem epoxy

Cov xov xwm tshwj xeeb: rau cov kav dej uas yuav tsum tau ua haujlwm siab (xws li cov roj av roj av), sab hauv yuav rov qab ua kom tsis txhob muaj kev sib txhuam.

Tshaj tawm -}}}}}}} kev kho mob: sandblasted steel kav muaj nyiaj {{1} grey grey grey xim zoo nkauj. Txhawm rau tiv thaiv xeb thaum lub sijhawm thauj mus los thiab luv- lub sij hawm cia, ib txheej sib yuav, ib qho nyias nyias cia, ib qho txheej txheem weldable ib ntus lossis tus neeg sawv cev feem ntau yog thov. Cov yeeb yaj kiab nyias nyias tsis muaj kev cuam tshuam rau tom qab ntawm - chaw vuam thiab corrosion corrosion {}} tiv taus txheej.

Txog Peb
