1. Dab tsi yog "Heat Number" thiab vim li cas thiaj tseem ceeb?
Tus lej Kub Kub yog tus cim tshwj xeeb rau ib pawg tshwj xeeb ntawm cov hlau molten. Nws tso cai rau tag nrho traceability ntawm cov tshuaj muaj pes tsawg leeg thiab txhua yam kev xeem tau rov qab mus rau lub qub zeb xeem daim ntawv pov thawj (MTR).
2. MTR yog dab tsi?
Ib MTR, orMill Test Report, yog ib daim ntawv pov thawj los ntawm cov chaw tsim khoom steel uas muab cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov yeeb nkab tshwj xeeb, txheeb xyuas los ntawm kev sim. Nws yog ib qho tseem ceeb ntawm daim ntawv pov thawj zoo.
3. A106 Qib B puas tuaj yeem galvanized?
Yog lawm, A106 Qib B tuaj yeem kub-dip galvanized los muab zinc txheej rau kev tiv thaiv corrosion. Qhov no tsim cov khoom lag luam uas sib xyaw ua ke siab - kub lub zog nrog rau sab nraud corrosion kuj.
4. Dab tsi yog qhov txawv ntawm "Schedule" thiab "Wall Thickness"?
"Schedule" (piv txwv li, Sch 40, Sch 80, Sch 160) yog cov txheej txheem txheej txheem uas cuam tshuam rau phab ntsa thickness rau ib qho NPS. Qhov tseeb phab ntsa thickness tus nqi (piv txwv li, 0.154 "rau NPS 2 Sch 40) yog qhov tseeb ntsuas.
5. Puas yog A106 tau txais ASTM A105 fittings?
Yog, qhov no yog qhov sib xyaw ua ke ntau heev.ASTM A105 1yog tus qauv rau forged carbon steel piping Cheebtsam (xws li flanges, luj tshib, thiab fittings) npaj rau ambient thiab siab - kev pab kub. Lawv cov khoom siv tshuaj lom neeg zoo sib xws ua rau A106 yeeb nkab thiab A105 fittings tus qauv sib tw rau siab -kub siab tshuab.
