Carbon Steel Pipe Supplier & Stockist
Octal Pipe ua haujlwm raws li ob qho tib si acarbon steel yeeb nkab tsumrau zeb xaj thiab acarbon steel yeeb nkab stockistrau ceev- taug qab qhov project xav tau. Rau cov qauv loj siv hauv cov kav dej, cov kav dej, thiab cov kav dej ua lag luam, peb txhawb nqa luv luv - lub sijhawm khoom siv los ntawm kev sib txuas cov khoom lag luam nrog cov phiaj xwm tsim khoom batch - yog li kev yuav khoom tuaj yeem ua raws cov khoom xa tuaj mus rau qhov chaw ua haujlwm ua ntu zus es tsis txhob tos rau ib lub mills tag nrho.
Qhov no txhais li cas hauv kev xyaum:
Stockist{0}}style xa:OD / WT / cov qhab nia tuaj yeem npaj tau sai nrog cov npe ntim meej, kev tiv thaiv kawg, thiab kev xa khoom xa tuaj rau qhov chaw tau txais.
Tus neeg muab khoom-style project pob:rau tsis yog-tus qauv OD/WT, nruj dua PSL/kev soj ntsuam, lossis cov yeeb nkab coated, peb muab cov khoom tsim tawm + tshuaj xyuas + cov ntaub ntawv rau hauv ib pob tso tawm.
Cov ntaub ntawv uas phim qhov chaw tso tawm:MTC thiab cov ntaub ntawv tshuaj xyuas tau teeb tsa los ntawm ntau yam kom QA tuaj yeem sib koom ua ke cov cim thiab cov ntaub ntawv tsis muaj tuav cov ntaub ntawv tom qab xa khoom.
Seamless vs Welded Carbon Steel Yeeb Nkab: Xaiv Qhia
Seamless Carbon Steel Pipe (Thaum lub luag haujlwm tseem ceeb)
Seamlesscarbon steel yeeb nkabyog tsim los ntawm kub dov thiab / los yog txias daim duab uas tsis muaj longitudinal weld seam. Nws yog feem ntau teev thaum lub luag haujlwm yogkub siab/siab kub, thaum muajhnyav cyclic loading, los yog thaum qhov project specification qhia meej meej hais tias "seamless nkaus xwb."
Piv txwv li:chav thiab siab -kub siv hluav taws xob headers hauv cov chaw tsim hluav taws xob, chav tsev refinery piping (cov roj kub / cov txheej txheem kab), thiab cov txheej txheem tseem ceeb uas cov neeg siv xav tshem tawm weld-seam tshuaj xyuas qhov pheej hmoo. Hauv cov pob khoom no, Octal Pipe feem ntau txhawb nqa kev yuav khoom los ntawm kev lees paub qhov tseeb / qib thiab xa ib daim ntawv teev MTC raws li qhov project cov ntaub ntawv tshuaj xyuas kev ua haujlwm.
Welded Carbon Steel Yeeb Nkab (Thaum OD ntau thiab kev xa khoom zoo teeb meem)
Welded carbon steel yeeb nkab npogERW, LSAW, SSAW/HSAW, and EFWtxheej txheem. Nws yog feem ntau xaiv rauloj diameters thiab ntev ncaj khiav, thiab rau tej yaam num uas lub sij hawm nyob ntawmruaj khov ntim khoomthiab kwv yees haum -up.
Piv txwv li:API 5L kab yeeb nkab tej pob khoom rau onshore kis tau tus mob segments, dej lub cev thiab cov kav dej, thiab piling/structural tes tsho qhov chaw ua hauj lwm xav tau raws li OD / WT kom ceev ceev kev sib raug zoo. Octal Pipe feem ntau pab cov haujlwm no los ntawm kev sib piv txoj kev welded rau qhov yuav tsum tau ua (ERW rau me me / nruab nrab OD, LSAW rau siab dua -thov ncaj seam tej pob khoom, SSAW / HSAW rau loj OD kis tau tus mob), thiab qhia meej txog seam lees txais (UT / RT / hydrotest yog tias xav tau) hauv PO txhais tau tias qhov chaw tso tawm tsis tau tso tawm.

| Dub / Varnish | Kev cia sab hauv tsev, luv -lub sij hawm tiv thaiv corrosion, dav dav kav | Khw- siv rau kev tuav / khaws cia; tsis ntev -lub sij hawm tiv thaiv -corrosion system |
| Galvanized (HDG / Electro) | Sab nraum zoov raug, kab siv hluav taws xob, lub teeb corrosion ib puag ncig | Paub meej txheej txheej txheem, zinc thickness, thiab xov haum (yog T & C) |
| FBE (Fusion Bonded Epoxy) | Cov kav dej faus, kab dej, nruab nrab av corrosion | Cov txheej txheem txheej txheem; txhais DFT thiab kev txais nyiaj so koobtsheej yog tias xav tau |
| 3 LPE / 3PE | Cov kab faus, cov av txhoj puab heev, xav tau kev tiv thaiv txhua yam | Muaj zog mechanical tiv thaiv; qhia txheej txheej thiab thickness |
| Internal Epoxy / Hauv ob sab phlu (raws kev thov) | Dej, slurry, los yog corrosion -sensitive internal media | Txhais hom kab, thickness, thiab sab hauv qhov chaw txais cov qauv |
Cov ntawv thov tseem ceeb (Qhov chaw ua haujlwm & Cov yeeb nkab ua haujlwm li cas)
- Pipeline kis tau (stringing → vuam → txo qis -in):
Nyob rau ntev ROW kis tau tus mob, cov yeeb nkab yog pheej lifted, teem cia, aligned, welded, thiab qis rau hauv trench. Cov ntsiab lus mob tiag tiag yoghaum- ncua sij hawm(ovality / ncaj), ntxiv rauqhov chaw tso tawm tuav cov ntsiab lusthaum cov cim thiab cov ntaub ntawv tsis sib xws. Octal Pipe feem ntau txhawb nqa cov pob khoom no nrog kev tswj hwm OD/WT thiab tso tawm -cov ntaub ntawv npaj txhij (MTC + ntau daim ntawv qhia), yog li kev sib kis tsis qeeb los ntawm kev rov ua dua - cov ntawv txheeb xyuas thiab cov ntaub ntawv sib txawv.
- Lub nroog qhib- txiav tej hauj lwm (ntub trenches, ceev backfill windows):
Thaum lub sij hawm siv dej los yog kev tsim kho, cov neeg ua haujlwm ua haujlwm hauvav nkos trench, feem ntau nrog cov dej hauv av thiab cov sijhawm kho kom nruj. Txheej kev puas tsuaj thiab kev kho hnub so tuaj yeem dhau los ua tus neeg tua neeg zais cia ua ntej rov qab ua dua. Rau cov hauj lwm no, Octal Pipe cov pa roj carbon steel yeeb nkab feem ntau raug txiav txim nrog FBE / 3LPE cov kev xaiv thiab kev tiv thaiv qhov kawg yog li tuav thiab ua kom muaj kev sib chwv tsawg dua -ua rau xav tsis thoob ntawm qhov chaw.
- Piling & lub hauv paus ua haujlwm (hnyav nqa, tsav tsheb, sib dhos):
Hauv cov pawg choj thiab cov hauv paus hauv tsev, cov kav dej tau ua haujlwm nyob rau hauv cranes, tig, thiab tsav -geometry thiab qhov kawg ntawm kev txiav txim siab seb qhov kev ua haujlwm zoo li cas. Tsis zoo roundness los yog inconsistent kawg ua rauyuam kev sib dhos thiab rov ua haujlwmthaum haum- nce lossis tsav tsheb. Octal Pipe feem ntau tsom rau qhov kev ruaj ntseg ntawm qhov ntev thiab qhov kawg kev npaj ua kom zoo sib xws los txo cov kev cuam tshuam ntawm thaj chaw no.
- Slurry / abrasive thauj ( yaig + sab hauv corrosion):
Hauv kev ua haujlwm mining thiab slurry, qhov tsis ua haujlwm yog feem ntaukev yaigthiab localized internal hnav es tsis yooj yim siab. Tej yaam num feem ntau qhia cov phab ntsa hnyav dua los yog hauv ob sab phlu kom ntev kev pab cuam lub neej. Octal Yeeb Nkab tuaj yeem muab cov pa roj carbon steel yeeb nkab nrog cov txheej txheej / txheej txheej kom cov yeeb nkab zoo sib xws rau cov kev pabcuam abrasive yam tsis muaj kev vam khom rau kev tsim kho.
Vim li cas Carbon Steel Pipe los ntawm Octal Yeeb Nkab
- Ib - qhov kev pab cuam thoob plaws txoj kev:Octal Yeeb Nkab Coordinatesseamless + ERW + LSAW + SSAW / HSAWmuab nyob rau hauv ib qho kev tshaj lij, uas yog qhov tshwj xeeb tshaj yog thaum ib qhov project sib xyaw me me / nruab nrab OD cov txheej txheem nrog loj -OD kis lossis piling- kev yuav khoom tsis txhob faib cov neeg muag khoom thiab rov ua cov ntaub ntawv.
- Factory-tswj weld & forming zoo (qhov twg buyers audit):Ntawm cov pob khoom welded, kev tsim ua kom pom tseeb yogtxoj kev ruaj ntseg + weld seam tswj, nrog seam lees txais ua raws li qhov yuav tsum tau ua ntawm qhov project thiab sau los ntawm ntau ntau -yog li cov neeg siv tshuaj xyuas cov chaw pov thawj, tsis yog piav qhia.
- Tso cov pob khoom uas phim EPC / qhov chaw ua haujlwm:Es tsis txhob xa cov ntaub ntawv tawg, Octal Pipe compilesMTC + NDT/hydro/mechanical recordsrau hauv ntau ntau -raws li teeb tsa uas qhia ncaj qha rau cov cim yeeb nkab. Qhov no txo qhov "cov yeeb nkab tuaj txog tab sis tsis tso tawm" ncua thaum tau txais thiab tshuaj xyuas.
- Chaw ua haujlwm -npaj batching thiab cim:Kev xa khoom tuaj yeem raug teeb tsalos ntawm qhov loj / ntau hauv kev teeb tsa ua ntu zus(piv txwv li, stringing → haum-up → vuam), nrog rau cov ntaub ntawv pov thawj tseeb thiab cov npe ntim khoom- txiav lub sijhawm ntawm qhov chaw nkim rau kev txheeb xyuas thiab caum cov khoom ploj.
- Xaus / txheej thiab export ntim ua tiav rau kev thauj mus los tiag:BE/PE ntxiv rau kev xaiv txheej txheej (xws li,FBE / 3 LPE) tuaj yeem ua haujlwm nrog cov yeeb nkab xa khoom, tom qab ntawd xa nrogkev tiv thaiv kawg thiab pob khoom / steel-thav duab ntim- pab tau thaum lub sij hawm nruj thiab qhov project tsis tuaj yeem them nyiaj ntxiv thib peb - tog kev ua haujlwm lossis kev thov puas tsuaj.
