Superior x65 swsaw kab cov yeeb nkab: kev daws teeb meem zoo rau kev ua tau zoo thiab txhim khu kev qha pipeline
Qhia:
Raws li kev lag luam nthuav dav thiab cov neeg loj hlob, qhov xav tau kev thauj mus los tau zoo ntawm cov roj, roj av, thiab lwm yam ntaub ntawv dhau los ua qhov tseem ceeb ntxiv tseem ceeb. Kev tsim kho thiab kho cov raj xa hluav taws xob ua rau lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev kub ntawm cov khoom siv thoob ntiaj teb. Hauv qhov no,X65 Ssaw Kab Yeeb NkabTau tshwm sim raws li kev txiav cov tshuaj txiav, xa cov khoom zoo tshaj plaws thiab tsis muaj kev sib raug zoo hauv kev ua haujlwm hauv nkoj.

Dab tsi yog X65 kauv submerged arc welded kab yeeb nkab?
X65 sws (subrerged arc welded) kab yeeb nkab yog ib hom hlau yeeb dav siv nyob rau hauvraj dejKev tsim kho hauv cov roj thiab roj kev lag luam. Kab no cov yeeb nkab sib xyaw ua ke ntawm lub zog, durability thiab zoo kawg nkaus tau ua rau nws xaiv thawj zaug rau ntau yam haujlwm thoob ntiaj teb.
Lub zog thiab durability:
Ib qho ntawm cov tseem ceeb uas cais x65 kauv submerged arc Welded Kab Yeeb Nkab yog nws qhov tshwj xeeb thiab lub zog. Ua los ntawm cov hlau zoo, nws muaj zog tsis kam rau sab hauv thiab sab nraud siab. Qhov no ua rau nws qhov kev xaiv zoo tshaj plaws rau kev thov cov roj thiab roj av, ua kom muaj peev xwm txhim khu kev qha thiab ntev-ntev.
Pipeline ua haujlwm tau zoo:
Kev ua tau zoo yog qhov tseem ceeb thaum thauj cov peev txheej los ntawm Pipelines. X65 Ssaw Kab Yeeb Nkab Yeeb Yam Hauv Cheeb Tsam, muab cov dej ntws du nrog kev sib txhuam tsawg, yog li kev txo hluav taws xob thaum thauj khoom. Qhov kev ua tau zoo no pab cawm cov nqi thiab txo kev cuam tshuam ib puag ncig, ua rau muaj kev xaiv ib puag ncig ib puag ncig.
