Kev lag luam fais fab: Siv rau boiler, chav turbine, siab pipeline thiab lwm yam khoom siv txuas.

Lwm yam kev lag luam: xws li nkoj tsim, metallurgy, machinery thiab lwm yam lag luam kuj tau dav siv A193 B7 xov pas nrig.

3. Machining thiab zoo tswj ntawm A193 B7 xov pas nrig

A193 B7 threaded pas nrig machining txheej txheem suav nrog:

Kev xaiv cov khoom siv: nruj me ntsis tswj cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm raw khoom.

Kev kho cua sov: txheej txheem kev kho cua sov yog siv los xyuas kom meej cov khoom zoo tshaj plaws ntawm cov khoom.

Xov xov: Siv dov los yog sib tsoo txheej txheem los ua cov xov kom paub meej xov raug thiab nto zoo.

Kev kho deg: Raws li kev siv ib puag ncig los xaiv qhov kev kho kom zoo, xws li galvanized, phosphating, dacromet, thiab lwm yam.

Cov txheej txheem tsim khoom ntawm A193 B7 xov pas nrig yuav tsum muaj kev tswj xyuas nruj kom ntseeg tau tias cov khoom ua tau raws li cov cai ntawm ASTM A193 tus qauv.

4. Kev xaiv thiab kev teeb tsa ntawm A193 B7 xov pas nrig

Thaum xaiv covA193 B7 xov pas nrig, cov hauv qab no yuav tsum tau xav txog:

Specification loj: Raws li qhov loj thiab quab yuam ntawm lub connector xaiv qhov tsim nyog specification ntawm cov hniav.

Qib Kev Ua Haujlwm: Xaiv qib kev ua tau zoo raws li kev siv ib puag ncig thiab kev ua haujlwm.

Kev kho deg: Xaiv qhov kev kho saum npoo tsim nyog raws li kev siv ib puag ncig.

Thaum txhim kho A193 B7 threaded pas nrig, nco ntsoov cov hauv qab no:

Clean thread: Ntxuav xov ua ntej installation kom tshem tawm cov roj thiab impurities.

Siv cov roj nplua nyeem: Siv cov roj nplua nyeem uas tsim nyog rau ntawm cov xov kom txo qis kev sib txhuam.

Tswj lub preload: Siv lub torque wrench los yog hydraulic tensioner los tswj lub preload thiab xyuas kom meej ib tug txhim khu kev qha kev twb kev txuas.

5.Sum up

Nrog nws cov kev ua tau zoo heev thiab kev ntseeg siab, lubA193 B7 xovpas nrig yog ib qho tseem ceeb ntawm cov fastener nyob rau hauv qhov kub thiab txias. Nrog kev txhim kho txuas ntxiv ntawm kev lag luam thev naus laus zis, daim ntawv thov teb ntawm A193 B7 cov hniav yuav nthuav dav dua, thiab nws cov kev ua tau zoo yuav txuas ntxiv txhim kho, tiv thaiv kev nyab xeeb kev lag luam.
