Product Overview
SSAW (Spiral Submerged Arc Welded) steel yeeb nkab rau piling yog tsim los rau kev thauj khoom -cov khoom siv hauv cov hauv paus sib sib zog nqus, kev tsim kho hauv hiav txwv, thiab cov khoom siv hnyav. Tsim los ntawm helical nruam forming thiab ob -sided submerged arc vuam (DSAW), cov khoom no muab lub siab axial compression thiab dabtsi yog khoov tsis kam yuav tsum tau hloov hnyav superstructure loads mus rau muaj peev xwm bedrock los yog load- bearing strata.

Kev Tswj Xyuas Zoo & Kev Tshuaj Xyuas
Cov qauv kev ncaj ncees nyob rau hauv lub hauv paus engineering yuav tsum tau nruj me ntsis xyuas ntawm ob raw steel thiab tiav weld seams.
Incoming Coil Inspection:Cov khoom kub kub-rolled coils raug txheeb xyuas rau cov thickness profile, deg mob, tensile zog, thiab Charpy V-notch cuam tshuam toughness.
Weld Seam Test:
- 100% online lossis offline Ultrasonic Testing (UT) raws tag nrho cov kauv vuam seam.
- Real-time industrial X-ray imaging for weld ends.
Kev Ntsuas Hydrostatic:Ua raws li tus qauv yuav tsum tau ua kom paub tseeb cov kev txwv sab hauv siab uas muaj feem xyuam.
Dimensional Auditing:Automated thiab phau ntawv laser ntsuas ntawm txheej kab, phab ntsa thickness, bevel geometry, thiab ntev.
Manufacturing & Supply Capability
Cov kab ntau lawm:4 ywj siab siab - muaj peev xwm SSAW cov kab tsim khoom.

Anti-Corrosion Facilities:Nyob rau hauv - daim ntawv thov tsev ntawm 3PE sab nraud (Peb- Txheej Polyethylene), FBE (Fusion Bonded Epoxy), thee tar enamel, thiab cov kua epoxy hauv ob sab phlu.
Shipping Logistics:Kev nkag ncaj qha mus rau cov khoom siv loj tuav cov chaw nres nkoj thiab cov thawv ntim khoom rau kev xa tawm hauv tsev thiab thoob ntiaj teb.
Daim ntawv thov
Marine Infrastructure:Jetty pilings, dolphin pawg, offshore platform tsho ob txhais ceg, thiab quay phab ntsa.
Deep Foundations:Load-cov kabmob uas tau tsav los yog dhuav- nrum- nyob rau hauv - qhov chaw rau cov tsev siab - nce siab, cov nroj tsuag hnyav, thiab txoj kev loj / tsheb ciav hlau choj piers.

FAQ
Q: Dab tsi yog qhov siab tshaj plaws ib zaug -ntev muaj peev xwm ntau lawm yam tsis muaj welds circumferential?
A: Ib leeg txuas txuas tuaj yeem tsim tau txog li 18 meters yam tsis tas yuav tsum muaj lub voj voog (circumferential) welds, txo qhov chaw vuam lub sij hawm thiab tshem tawm cov qauv tsis muaj zog.
Q: Yuav ua li cas yog lub kauv weld seam txheeb xyuas kev nyab xeeb nyob rau hauv hnyav dynamic tsav loads?
A: Txhua lub meter ntawm cov kauv vuam tau dhau 100% automated ultrasonic kuaj (UT) txhawm rau txheeb xyuas sab hauv thiab saum npoo -tawg qhov tsis sib xws, txhawb nqa los ntawm kev soj ntsuam ib ntus (RT).
Q: Koj puas tuaj yeem muab cov khoom hnyav- phab ntsa tuab rau kev tsav tsheb los ntawm tuab lossis pob zeb strata?
A: Yog. Phab ntsa thicknesses txog li 25 hli tuaj yeem tsim tau siv high - cov khoom siv hlau (xws li ASTM A252 Gr. 3 lossis EN 10219 S355J2H) kom tiv taus kev tsav tsheb siab thiab buckling rog.
Q: Dab tsi los tiv thaiv - kev xaiv txheej txheej corrosion muaj rau kev ua phem hauv hiav txwv?
A: Cov txheej txheem kev xaiv muaj xws li 3- txheej polyethylene (3PE) ib DIN 30670 / ISO 21809, fusion bonded epoxy (FBE), los yog hnyav-duty marine barrier systems tsim los ua ke nrog cathodic tiv thaiv.
Q: Dab tsi yog kev tswj hwm kev kam rau sab nraud thiab qhov ncaj?
A: Txoj kab uas hla kev ua raws li nruj me ntsis rau ASTM A252 / EN 10219 cov lus qhia tshwj xeeb (feem ntau ntxiv lossis rho tawm 0.75% ntawm nominal OD), thiab kev sib txawv ncaj qha yog tswj hauv<= 0.2% of total length.
Q: Cov ntaub ntawv ua raws li cas yog muab rau kev taug qab qhov project?
A: Txhua batch nkoj nrog EN 10204 3.1 MTC muaj cov naj npawb ntawm cov cua sov, tshuaj ntsuam xyuas muaj pes tsawg leeg, cov txiaj ntsig kev ntsuas tshuab, NDT cov ntaub ntawv, thiab cov ntaub ntawv seem.
