Due to its special shape, stainless steel square pipes have different methods for processing their pipe fittings. Let's take a look at them:
Tus nqi ntawm cov yeeb nkab fittings yog muab faib ua forging, stamping, roller, dov, dabtsi yog khoov, expansion thiab lwm yam. Tam sim no, ntau txoj kev ua tau qhia raws li hauv qab no:
1. Forging txoj kev: Qhov kawg los yog ib feem ntawm lub raj yog xuas nrig ntaus thiab ncab nrog lub tshuab swaging kom txo tau cov kab sab nraud. Feem ntau siv swaging tshuab muaj xws li teb, txuas pas nrig thiab cov menyuam hom.
2. Stamping txoj kev: Cov yeeb nkab kawg tau nthuav dav mus rau qhov yuav tsum tau muaj qhov loj thiab cov duab nrog cov tub ntxhais tapered ntawm lub tshuab xuas nrig ntaus.
3. Bulging txoj kev: ib qho yog muab cov roj hmab tso rau hauv lub raj thiab compress nws nrog ib tug punch kom lub raj protrude rau hauv cov duab; Lwm txoj kev yog hydraulically inflate lub puab, sau nruab nrab ntawm lub raj nrog kua, thiab cov kua siab yuav bulge lub raj mus rau hauv lub xav tau kev pab. Zoo li, hauv qab yog feem ntau ua nyob rau hauv no txoj kev.
4. Txoj kev khoov txoj kev: Muaj peb txoj kev siv ntau, ib txoj kev hu ua stretching method, lwm txoj kev hu ua stamping method, thiab peb txoj kev rau cov menyuam muaj 3-4 rollers, ob lub taag rollers, thiab ib qho kev kho cov menyuam. Nrog rau qhov kev ncua deb, cov yeeb nkab tiav yog khoov.
5. Cov txheej txheem ntawm cov menyuam: muab cov tub ntxhais tso rau hauv lub raj, thiab thawb lub voj voog sab nraud nrog rau cov menyuam rau kev ua haujlwm ntawm ntug.
6. Rolling txoj kev: feem ntau tsis muaj mandrel, nws yog haum rau lub puab ntug ntawm tuab -walled kav.
