Kev txais yuavbulk cargo anti-kev sib tsoo kev ntim khoomhaum rau hiav txwv freight, tag nrho yoog mus rau ntev -kev thauj mus los hauv hiav txwv thiab ntau- tuav haujlwm:
- Cov yeeb nkab bevel kawg yog tiv thaiv los ntawm cov yas kawg kaus mom kom tsis txhob muaj kev sib tsoo deformation, khawb thiab vuam nto puas.
- Mos roj hmab spacers tau ntxiv ntawm cov kav dej sib txuas kom tiv thaiv kev sib txhuam thiab txheej txheej tev tawm
- Integral steel strapping + waterproof woven fabric wrapping, rainproof, dustproof thiab anti- xoob
- Bulk stowage rau kev txiav txim loj kom ua kom lub thawv thauj khoom ntau tshaj plaws thiab txo tus nqi logistics
- Kev cai cim (tus qauv steel qib, qhov loj me, tus qauv, batch naj npawb, qhov hnyav) ntawm txhua cov yeeb nkab kom yooj yim txheeb xyuas thiab lees txais

nthuav qhia Dub Anti-xeb Varnish Txheej
Cov kua roj vanish sab nraud yog tus nqi - tiv thaiv kev tiv thaiv ib ntus. Cov xim zoo nkauj, du dub xim zaj duab xis nruj ua raws li cov yeeb nkab nto, zoo cais cov huab cua, noo noo thiab plua plav los tiv thaiv oxidation nto thiab xeb thaum lub sij hawm luv luv - lub sij hawm cia, tsheb thauj mus los thiab kev pabcuam sab hauv. Nws nta ceev kom qhuav, khawb tsis kam thiab tu yooj yim, haum rau cov pa ua lag luam pipeline tej yaam num uas tsis tshua muaj corrosion.
nthuav qhia 3LPE Anti- Corrosion Txheej
3LPE peb- txheej polyethylene los tiv thaiv- txheej txheej corrosion yog lub hauv paus siab- kawg tiv thaiv - xeb tshuaj rau ntev - cov kav dej thiab cov kav dej, muaj peb txheej ua haujlwm:
Thawj Txheej (Epoxy Primer): High-adhesion epoxy hmoov txheej, nruj nreem khi rau cov yeeb nkab steel nto, tiv thaiv tshuaj corrosion thiab nkag mus adhesion
Ob txheej (Adhesive Layer): Tshwj xeeb copolymer nplaum, txuas cov primer thiab txheej txheej PE kom tsis txhob txheej delamination
Thib peb (PE txheej txheej): High- ntom polyethylene txheej, muab kev tiv thaiv txhua yam tiv thaiv kev cuam tshuam, puas thiab sab nraud extrusion
3LPE txheej nta ultra- nqus dej tsawg, tshuaj tiv thaiv zoo heev (acid, alkali, ntsev), muaj zog txhua yam toughness, thiab lub neej kev pab cuam ntau tshaj 30 xyoo nyob rau hauv underground thiab marine ib puag ncig, dav siv nyob rau hauv hnyav sab nraum zoov thiab subsea pipeline tej yaam num.

FAQ
Q1: Dab tsi yog qhov txawv ntawm API 5L PSL1 thiab PSL2 rau GR.B steel yeeb nkab?
PSL1 yog tus qauv qauv yooj yim rau cov qauv kev tsim vaj tsev, nrog rau cov khoom siv tshuaj lom neeg thiab cov cuab yeej cuab tam, tsis muaj qhov yuav tsum tau kuaj xyuas, thiab tus nqi- zoo. PSL2 muaj qhov txwv tsis pub muaj kev txwv tsis pub muaj kev txwv, yuav tsum muaj tsawg- qhov ntsuas kub ntawm qhov ntsuas kub, cov txiaj ntsig nruj dua- tensile piv tswj thiab txhim kho tsis yog- cov qauv ntsuas kev puas tsuaj, haum rau siab - pheej hmoo thiab siab - kev ntseeg siab ntawm cov kav dej. Feem ntau cov haujlwm hauv pej xeem thiab cov qauv kev lag luam xaiv PSL1 qib.
Q2: Qhov siab tshaj plaws ua haujlwm kub ntawm 3LPE coated yeeb nkab yog dab tsi?
Tus txheej txheem 3LPE txheej txhawb kev ua haujlwm tsis tu ncua ntawm -40℃txog 80 degree, nrog rau qhov sib sib zog nqus siab siab txog 120℃. Rau ntev -lub sij hawm siab- kub ua hauj lwm tej yam kev mob siab tshaj 80 degree, 3LPP txheej yog pom zoo kom ua kom muaj kev tiv thaiv corrosion stability.
Q3: Koj puas tuaj yeem muab qhov ntau thiab tsawg thiab txheej tuab?
Yog lawm. Peb txhawb nqa tsis yog- qauv txheej txheej, phab ntsa thickness, yeeb nkab ntev customization, thiab tuaj yeem kho 3LPE txheej thickness raws li qhov project specifications (cov qauv hauv teb chaws, cov qauv kev lag luam lossis cov neeg siv khoom xav tau) kom phim cov kev xav tau ntawm geological thiab kev ua haujlwm sib txawv.
Q4: Cov ntawv xeem thiab daim ntawv pov thawj twg koj tuaj yeem muab tau?
Peb tuaj yeem muab cov ntaub ntawv pov thawj API, cov ntaub ntawv pov thawj ntawm lub Hoobkas (MTC), tshuaj lom neeg muaj pes tsawg leeg & cov cuab yeej ntsuas cov cuab yeej, 3LPE txheej kev xeem ntawv tshaj tawm, daim ntawv tshaj tawm kev soj ntsuam ultrasonic, thiab thib peb- cov ntaub ntawv tshuaj xyuas tog (SGS, BV, thiab lwm yam) raws li cov neeg siv khoom xav tau.
Q5: Puas yog ERW steel yeeb nkab tsim nyog rau faus roj thiab roj kav dej?
Yog lawm. API 5L GR.B PSL1 ERW steel kav yog cov ntaub ntawv pov thawj tsim nyog thoob ntiaj teb. Nrog 100% weld non-kev kuaj kev puas tsuaj thiab tus qauv 3LPE tiv thaiv- kev kho corrosion, lawv ua tau raws li kev nyab xeeb thiab kev pabcuam lub neej raws li cov pa roj faus, roj thiab dej xa mus rau cov kav dej, thiab tau siv dav hauv ntiaj teb nruab nrab thiab qis - cov kav dej siab.
Q6: Koj lub sijhawm xa khoom thiab kev xa khoom yog dab tsi?
Cov khoom lag luam zoo tuaj yeem xa tuaj hauv 7-10 hnub ua haujlwm; customized loj yuav siv sij hawm 15-25 hnub ua hauj lwm. Peb txhawb nqa hiav txwv freight, av freight thiab multimodal tsheb thauj mus los, thiab muab kev export ntim thiab thawv loading daws teeb meem.
