Siv cov roj hmab uas siv tau txuas rau hauv cov raj hluav taws xob siv hauv cov raj xa hluav taws xob kom hloov cov kev coj ntws, suav rau kwv yees li 80% ntawm cov yeeb nkab fittings. Lawv cov ntaub ntawv suav nrog hlau cam khwb cia, hlau stainless, ineloy steel, thiab lwm yam kev tsim khoom, nrog lwm cov txheej txheem xaiv raws cov khoom lossis phab ntsa tuab sib txawv. Cov khoom lag luam tau customatorized los ntawm kev sib sau txoj kev mus rau hauv kub {} - Cov qauv txias ntxiv ua ke sib faib ua ke thiab cov kav dej txias; los ntawm lub kaum sab xis rau 45 degree, 90 degree, 180 degree, thiab lwm yam; Thiab los ntawm nkhaus nkhaus rau hauv ntev {{11} punius (r} radius (r {} d) thiab luv {13} postus lauj kaub. The manufacturing process involves cutting round pipe billets, heating to 1200℃for piercing, followed by oblique rolling, continuous rolling, or extrusion forming, and sizing processing, with conical roller piercing machines commonly used to improve efficiency. Cov qauv muaj xws li GB / T12459-2017, ASME / ANSI, thiab lwm yam kev paub tab, muaj feem xyuam rau Petrochemical, muaj feem xyuam rau kev sib tw, lub zog, nkoj, thiab lwm daim teb.
