Cov khoom no yog ibLongitudinal Submerged Arc Welded (LSAW)carbon steel kab yeeb nkab tsim nyob rau hauv tag nrho ua raws liAPI 5L PSL2standard, npog ob qib mainstream:X65MthiabX70M. Tsab ntawv "M" qhia tias thermo-mechanical controlled processing (TMCP), uas tso cai rau cov yeeb nkab uas muaj qhov tsis zoo heev -kub toughness, ruaj khov txhua yam khoom thiab superior weldability piv nrog cov pa roj carbon monoxide. Tag nrho cov kav dej tiav nrog3LPE (3-txheej Polyethylene)sab nrauv los tiv thaiv-corrosion txheej, txhim khu kev qha tshaj plaws los tiv thaiv -corrosion tov rau ntev - roj & roj xa mus kav.

LSAW yeeb nkab tau txais ib qho -daim steel phaj dov thiab ob npaug -sab submerged arc vuam txheej txheem, featuring niaj hnub phab ntsa thickness, siab roundness, me me vuam residual kev nyuaj siab thiab siab structural stability. Raws li qib siab - tus qauv PSL2 qib yeeb nkab, nws txhawb nqa nruj tsis yog - kuaj kev puas tsuaj, tsis tshua muaj sulfur thiab qis carbon muaj pes tsawg leeg tswj, thiab yuav tsum muaj kev cuam tshuam, tsim nyog rau kev ua haujlwm hnyav xws li ntev - kis tau tus mob, siab siab, qis kub thiab corrosive ib puag ncig.

4.Strict Quality Inspection & Testing

Tag nrho cov kav dej qib PSL2 siv tag nrho - kev tshuaj xyuas cov khoom kom ntseeg tau 100% ua raws li API 5L cov qauv:

Tshuaj ntsuam xyuas: Spectroscopic nrhiav kom tau tag nrho cov ntsiab lus, nruj me ntsis tswj cov pa roj carbon sib npaug thiab cov ntsiab lus impurity

Mechanical Test: Tensile test, dabtsi yog khoov test, Charpy low -temperature impact test, hardness test

Hydrostatic Pressure Test: Puv -ntev siab tswj kev ntsuas, tsis muaj qhov to, ruaj khov tus nqi

Q1: Qhov txawv ntawm PSL1 thiab PSL2 ntawm API 5L tus qauv yog dab tsi?

PSL2 yog qhov siab dua -qib cov khoom specification piv nrog PSL1. Nws muaj kev tswj xyuas cov tshuaj lom neeg nruj dua (qis C, P, S cov ntsiab lus), yuav tsum tsis tshua muaj - ntsuas qhov kub thiab txias, tag nrho- ntsuas qhov tsis zoo- kev ntsuas kev puas tsuaj, kev ua kom pom tseeb dua, thiab zoo dua qis - kub thiab kev nyab xeeb. PSL2 yog qhov yuav tsum tau ua rau qhov tseem ceeb ntev - nrug thiab siab - cov kav xa dej siab, thaum PSL1 tsuas yog tsim nyog rau cov pa qis - cov kav xa dej siab.

Q2: Qhov "M" hauv X65M / X70M txhais li cas? Dab tsi yog qhov zoo?

"M" yog hais txog Thermo-Mechanical Controlled Processing (TMCP). Sib txawv ntawm normalizing steel, TMCP dov optimizes steel microstructure los ntawm kev tswj dov thiab tswj txias, tsis muaj kev kho cua sov tom qab. Nws nta qis carbon sib npaug, zoo weldability, zoo heev low-kub brittleness tsis kam, thiab ruaj khov txhua yam khoom, zoo tsis txhob vuam tawg thiab pipeline fracture txaus ntshai nyob rau hauv qis-kub ib puag ncig.

Q3: Vim li cas thiaj xaiv LSAW yeeb nkab es tsis txhob seamless los yog kauv welded yeeb nkab?

LSAW yeeb nkab yog tsim los ntawm ib leeg steel phaj dov nrog ob -sided submerged arc vuam, nrog cov phab ntsa tuab tuab, siab roundness, tiaj weld seam thiab me me residual stress. Piv nrog seamless yeeb nkab, nws txhawb txoj kab uas hla loj dua thiab tuab phab ntsa customization nrog tus nqi qis; Piv nrog rau cov kav hlau welded, nws muaj luv weld seam, muaj kev nyab xeeb dua, tsis muaj kauv kev ntxhov siab, thiab yog qhov tsim nyog rau siab -siab, ntev- deb ntawm qhov tseem ceeb pipeline project.

Q4: Dab tsi yog qhov kev pab cuam lub neej ntawm 3LPE tiv thaiv -corrosion txheej?

Raws li cov txheej txheem faus ua haujlwm, 3LPE txheej muaj lub neej ua haujlwm ntawm 30-50 xyoo. Nws tuaj yeem tiv taus av corrosion, microbial corrosion thiab cathodic aging. Kev tswj cov txheej txheem nruj nruj thiab kev kuaj xyuas lub Hoobkas kom paub meej tias tsis muaj txheej txheej puas tsuaj, uas ua rau lub voj voog ua haujlwm zoo heev thiab txo cov nqi kho tom qab.

Q5: Koj puas tuaj yeem muab cov kev qhia tshwj xeeb thiab thib peb -kev tshuaj xyuas tog?

Yog lawm. Peb txhawb kev cai sab nraud txoj kab uas hla, phab ntsa thickness, ruaj ntev, qis- qhov kub thiab txias tsis kam thiab txheej thickness. Peb tuaj yeem muab cov ntaub ntawv soj ntsuam thib peb los ntawm SGS, BV, TUV thiab lwm lub koom haum tso cai, thiab muab cov ntawv pov thawj ua tiav nrog rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, cov ntaub ntawv xeem thiab cov ntaub ntawv pov thawj API.

Q6: Koj lub sijhawm xa khoom thiab lub sijhawm ua haujlwm yog dab tsi?

Peb txhawb EXW, FOB, CFR, CIF thoob ntiaj teb kev lag luam nqe lus. Cov lus qhia tshwj xeeb muaj cov khoom txaus nrog 7-10 hnub xa khoom; customized tsis yog - qauv specifications siv 15-25 hnub ntau lawm voj voog. Peb muab kev ntim khoom ntim, tiv thaiv kev sib tsoo thiab ua tiav cov ntaub ntawv xa khoom.
