Txhais thiab Standard Background
Welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab yog lub hom phiaj dav dav welded yeeb nkab siv los xa dej, roj, cua, roj, cua sov chav thiab cov kua dej tsis zoo. Hauv Suav system cov khoom tau teev tseg los ntawm GB / T 3091, uas npog ob qho tib si welded yeeb nkab, feem ntau hu ua cov yeeb nkab dub, thiab kub dip galvanized welded yeeb nkab, feem ntau hu ua yeeb nkab dawb. Cov laus GB / T 3092 kev xaiv rau cov yeeb nkab dav dav tau raug tshem tawm thiab nws cov peev txheej tau nqus rau hauv GB / T 3091, yog li ob qho tib si dub thiab galvanized cov khoom tam sim no raug txiav txim rau tib tus qauv.
Khoom siv thiab kev tsim khoom
Cov yeeb nkab yog tsim los ntawm carbon steel sawb los yog coil, welded los ntawm hluav taws xob kuj welding, ces loj, straightened thiab sim. Cov qib hauv paus muaj xws li Q195, Q215, Q235 thiab Q355 raws li tau teev tseg hauv GB / T 700 thiab GB / T 1591. Galvanized yeeb nkab yog tsim los ntawm kub dip galvanizing tom qab vuam, yog li txheej txheej npog sab nraud thiab, thaum teev, sab hauv thiab sab nraud.

| Kev xa khoom ntev | Random ntev, feem ntau 4 m txog 12 m |
| Kev sim | Hydrostatic kuaj rau lub siab muab rau hauv tus qauv, ntxiv rau txheej txheej pov thawj rau cov yeeb nkab galvanized |
Daim ntawv thov
Kev siv cov khoom siv yog cov dej hauv nroog thiab cov dej ntws tawm, cov xaim hluav taws xob sib txuas, lub tsev cua sov thiab qhov cua, compressed cua tshuab, ceg tiv thaiv hluav taws, kev ua liaj ua teb irrigation, tsev cog khoom thiab cov txheej txheem dav dav lossis kev txhawb nqa cov kav dej. Galvanized yeeb nkab yog nyiam sab nraum zoov thiab hauv qhov chaw ntub dej, vim tias cov zinc txheej muab kev tiv thaiv kev txi ntawm cov npoo thiab qhov chaw puas.
Ordering thiab Inspection Points
Qhia lub nominal txoj kab uas hla, lub sij hawm ntawm phab ntsa, daim ntawv kawg, lub nto tiav thiab tus me nyuam ntev, vim hais tias cov kev xaiv no tsis interchangeable: ib tug zoo tib yam phab ntsa yeeb nkab yuav tsis tau hloov mus rau ib tug thickened phab ntsa yeeb nkab ntawm tib lub siab tsim. Rau cov yeeb nkab threaded, paub meej tias cov xov hom thiab qhov kev sib txuas lossis lub hau yuav tsum tau ua, txij li cov kab sib txuas thiab tapered kaw cov xov tsis sib hloov. Rau cov yeeb nkab galvanized, paub meej tias qhov chaw sab hauv yuav tsum tau coated thiab cov txheej txheej twg siv, thiab xyuas cov cim, cov ntaub ntawv ntsuas hydrostatic thiab cov txheej txheem kuaj ua ntej xa khoom. Khaws cov khoom tiv thaiv kawg nyob rau hauv qhov chaw thaum thauj kom tsis txhob muaj kev puas tsuaj rau cov xov thiab bevels.
FAQ
Q: Dab tsi yog qhov txawv ntawm cov yeeb nkab dub thiab cov yeeb nkab dawb?
Cov yeeb nkab dub yog cov yeeb nkab ncaj nraim raws li nws los ntawm lub zeb, thaum cov yeeb nkab dawb yog tib cov yeeb nkab tom qab kub dip galvanizing. Ob lub npe piav qhia qhov ua tiav saum npoo, tsis yog qhov sib txawv ntawm qhov ntsuas.
Q: Tus qauv twg tswj cov khoom no?
GB / T 3091 npog welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab, suav nrog cov ntawv dawb thiab galvanized. Kev rho tawm GB / T 3092 tau muab tso rau hauv tus qauv no.
Q: Nominal diameter txhais li cas?
Nominal txoj kab uas hla DN yog ib qho yooj yim me me tsim ze rau hauv txoj kab uas hla. Nws tsis yog qhov tseeb qhov ntev, yog li sab nraud txoj kab uas hla thiab phab ntsa thickness yog qhov tseem ceeb los siv rau kev suav tsim.
Q: Dab tsi yog qhov txawv ntawm cov phab ntsa zoo tib yam thiab cov phab ntsa tuab tuab?
Lub sijhawm thickened muaj phab ntsa hnyav dua rau tib lub nominal txoj kab uas hla, uas ua rau lub siab muaj peev xwm thiab qhov nruj ntawm cov yeeb nkab. Ob chav kawm tsis hloov pauv hauv txoj kab uas muaj zog.
Q: Cov yeeb nkab puas tuaj yeem muab nrog cov xov?
Yog lawm. Plain kawg thiab threaded kawg kav yog ob qho tib si muaj, thiab daim ntawv xov yuav tsum tau teev nyob rau hauv kev txiav txim vim txawv xov txheem tsis tuaj yeem sib raug zoo.
Q: Qhov twg yog galvanized yeeb nkab nyiam?
Galvanized yeeb nkab yog nyiam rau sab nraum zoov, ntub dej los yog sib sib zog nqus kev pab cuam xws li dej, irrigation thiab kev siv cov nroj tsuag, qhov twg zinc txheej txwv atmospheric corrosion.
