Cov FAQ
Q: Dab tsi yog qhov txawv ntawm seamless thiab welded steel kav?
A: Cov kav dej seamless yog tsim tawm yam uas muaj ib lub zog, muab lub zog siab dua thiab siab dua - qhov siab thiab kev siv cuav.
Welded kav, ntawm qhov tod tes, yog tsim los ntawm kev sib sau thiab vuam hlau daim hlau lossis coils. They are cost-effective and suitable for medium- and low-pressure systems such as water, gas, or oil transmission pipelines.
Q: Dab tsi yog API 5L thiab nws yog dab tsi?
A: API 5L yog ib tus qauv thoob ntiaj teb tau muab los ntawm American cov chaw tsim hluav taws xob. Nws qhia txog qhov yuav tsum tau ua rau seamless thiab welded steel kab xaub kav siv rau kev thauj mus los ntawm cov roj, roj, thiab dej.
Octal yeeb nkab Khoom API 5L Kab Cov Kab B, X42 mus rau X80, nrog rau kev ua raws li ISO 3183, DNV, thiab NACE cov qauv.
Q: Dab tsi yog CRA clad thiab cov txiv hmab txiv ntoo?
A: CRA (corrosion - Resistant Alloy) cliges {}}}}}} rau cov pa roj carbon steel.
Cov qauv tsim no ua ke lub zog nrog corrosion tsis kam, ua rau lawv zoo tagnrho rau ntug dej hiav txwv, tshuaj chev cov nroj tsuag, thiab qaub cov ntawv thov.
Q: Dab tsi yog tus saib xyuas yeeb nkab siv rau hauv ntug dej?
A: Tus neeg saib xyuas cov yeeb nkab yog thawj loj loj - Inch casing teeb tsa hauv ntug dej hiav txwv. Nws muab seawebed stability, cais cov chaw dej hiav txwv, thiab ua lub hauv paus tseem ceeb rau lub wellhead thiab drilling risers.
Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv los ntawm 20 "-36" Od, mand, rau API thiab DNV tawm ntawm cov qauv.
Q: Lub ntsiab ntawm cov yeeb nkab fittings zoo li cas?
A: Cov yeeb nkab fittings suav nrog luj tshib, tees, reducers, caps, qij, stub xaus, thiab flanges.
Octal Yeeb Nkab muaj cov fittings hauv carbon hlau, alloy steel, hlau steel, stainless hlau, conforming} clad cov ntaub ntawv, conforming rau ASTM A234, A40.3, thiab ASME B16.9 cov qauv.
Q: Qhov sib txawv ntawm lsaw, swsaw, thiab erw steel kav?
A: LSAW (Longitudinal Submerged Arc Welded): Straight-seam welded pipes suitable for high-pressure pipelines.
SSAWerged arc welded): Muab kauv {{} Welded Pipes zoo tagnrho
ERW (hluav taws xob tiv thaiv welded): ua los ntawm hluav taws xob vuam ntawm hlau coils; siv hauv cov txheej txheem thiab roj & roj app.
