Jan 21, 2026
ASME B16.28 Wrought Steel Buttwelding Luv Radius Luj tshib thiab rov qab
ASME B16.28 tus qauv npog cov kev tsim khoom tshwj xeeb rau 90℃luv vojvoog luj tshib thiab 180℃luv vojvoog rov qab khoov. Cov ntaub ntawv muaj xws li carbon steel, qis alloy steel, thiab stainless hlau, ua raws li ASTM A234, A403, thiab A420 tus qauv. Qhov ntau thiab tsawg ntawm NPS 1/2 txog NPS 24. ANSI B16.28 taub qab- vuam fittings feem ntau yog siv rau hauv cov roj thiab roj, lub zog tsim hluav taws xob, petrochemical, thiab tshuaj lom neeg kev lag luam. Thov hu rau peb kom paub ntau ntxiv!
ASME B16.28 yog keeb kwm tus qauv rau pob tw - vuam yeeb nkab fittings thiab tau hloov dua tshiab hauv xyoo 1994.
Tam sim no tus qauv yogASME B16.9.
