ASTM A194 Cov khoom siv

ASTM A194 specification npog carbon, alloy thiab stainless hlau ceev rau siv nyob rau hauv high-pressure thiab/los yog high-temperature kev pab cuam. Tshwj tsis yog tias tau teev tseg, American National Standard Heavy Hex Series (ANSI B 18.2.2) yuav tsum tau siv. Cov txiv ntseej mus txog thiab suav nrog 1 nti nominal loj yuav tsum yog UNC Series Class 2B haum. Cov txiv ntseej tshaj 1 nti nominal loj yuav tsum yog UNC Series Class 2B haum lossis 8 UN Series Class 2B haum. Lub zog siab ASTM A194 qib 2H txiv ntseej yog muaj nyob rau hauv kev ua lag luam thiab feem ntau hloov rau ASTM A563 qib DH txiv ntseej vim qhov muaj tsawg ntawm DH txiv ntseej hauv qee qhov diameters thiab tiav.

CEEB TOOM: 1. Cov cim qhia rau txhua qib ntawm A194 txiv ntoo yog rau cov txiv ntoo txias thiab kub forged. Thaum cov txiv ntoo raug machined los ntawm cov khoom lag luam, cov txiv ntoo yuav tsum tau cim nrog tsab ntawv 'B'. Cov tsiaj ntawv H thiab M qhia txog cov txiv ntoo uas muaj cua sov. 2. Cov khoom qhia yog cov ntxhib thiab 8-pitch xov hnyav hex ceev. 3. Cov zauv Hardness yog Brinell Hardness. 4. Cov txiv ntoo uas muaj cov tshuaj carbide kho yuav tsum muaj tsab ntawv A – 8A lossis 8MA ntxiv. 5. Tag nrho cov txiv ntseej yuav tsum dais tus neeg tsim khoom lub cim cim. Cov txiv ntseej yuav tsum raug cim rau ntawm ib lub ntsej muag los qhia txog qib thiab txheej txheem ntawm cov chaw tsim khoom. Kev kos npe ntawm cov ciaj ntswj flats lossis bearing nto yog tsis tso cai tshwj tsis yog tias tau pom zoo los ntawm cov chaw tsim khoom thiab cov neeg yuav khoom. Cov txiv ntoo coated nrog zinc muaj lub hnub qub (*) cim tom qab lub cim qib. Cov txiv ntoo coated nrog cadmium yuav tsum muaj lub cim ntxiv (+) cim tom qab lub cim qib. 6.
