Khoov Test
Rau DN ≤ 50 [NPS ≤ 2], ntev txaus ntawm cov yeeb nkab yuav tsum muaj peev xwm khoov txias mus txog 90 ° nyob ib ncig ntawm lub cylindrical mandrel, lub cheeb ntawm uas yog kaum ob lub sij hawm cov teev sab nraud txoj kab uas hla ntawm cov yeeb nkab, tsis muaj kev txhim kho cov kab nrib pleb ntawm ib feem.
Muab ob npaug rau-muaj zog(XXS) yeeb nkab hla DN 32 [NPS 1 1/4] yuav tsum tsis txhob raug kuaj khoov.
Flattening Test
Seamless steel tubes tsis tas yuav raug rau qhov kev sim flattening.
Yog tias xav tau los ntawm daim ntawv cog lus, qhov kev sim tuaj yeem ua tiav raws li cov txheej txheem hauv S1.
Txhua qhov ntau thiab tsawg ntawm cov kav dej seamless steel yuav tsum tswj xyuas cov nqi dej siab yam tsis muaj qhov xau tsawg kawg 5 vib nas this.
Kev ntsuas siab rau cov kav hlau uas tsis tshua muaj siab tuaj yeem pom hauv Table X2.2.
Cov kev ntsuas siab rau cov kav hlau thiab cov kav hlau txuas txuas tuaj yeem pom hauv Table X2.3.
Nws tuaj yeem siv los ua lwm txoj hauv kev kuaj hydrostatic.

ASTM A53 tus qauv qhia cov kev cai rau cov yeeb nkab dub thiab kub-dip galvanized txheej ntawm cov kav hlau.
Cov yeeb nkab dub
Cov yeeb nkab dub yog hais txog lub xeev ntawm cov yeeb nkab steel yam tsis muaj kev kho deg.
Cov kav dej dub feem ntau siv rau hauv qhov chaw uas lub sijhawm khaws cia luv luv, ib puag ncig yog qhuav thiab tsis xeb, thiab tus nqi feem ntau qis dua vim tias tsis muaj txheej txheej.
Kub-dip Galvanized txheej
Galvanized kav, tseem hu ua cov kav dej dawb, feem ntau siv nyob rau hauv qhov chaw ntub dej los yog corrosive.
Cov zinc hauv zinc txheej tuaj yeem yog qib zinc hauv ASTM B6.
Cov yeeb nkab galvanized yuav tsum tsis pub dawb los ntawm qhov chaw tsis muaj coated, hlwv pob, flux deposits, thiab gross dross inclusions.Lumps, projections, globules, los yog hnyav deposits ntawm zinc uas yuav cuam tshuam nrog kev npaj siv cov khoom yuav tsis raug tso cai.
Zinc ntsiab lus tsis tsawg tshaj 0.55 kg/m² [1.8 oz/ft²].
Lwm Cov Txheej Txheem
Ntxiv nrog rau cov yeeb nkab dub thiab galvanized txheej, hom txheej txheej muaj xws lipleev xim, 3 LPE, FBE, thiab lwm yam. Cov txheej txheej tsim nyog tuaj yeem xaiv tau raws li cov kev xav tau tshwj xeeb ntawm qhov chaw ua haujlwm.
Kev muab cov ntaub ntawv hauv qab no yuav ua rau koj txoj kev yuav khoom zoo dua thiab raug.
