2. Vuam zoo
- Peb cov kav dej yog tsim los siv hluav taws xob tiv thaiv vuam (ERW) thev naus laus zis. Cov hlau tsis muaj steel yog txias- ua rau hauv cov duab cylindrical thiab tom qab ntawd longitudinally taub qab -welded siv cov vuam tsis kam. Tsis muaj cov hlau muab tub lim ntxiv, uas ua rau muaj qhov sib txuas zoo sib xws thiab cov qauv hlau tsis sib xws.
- Cov kav dej tau dhau los tom qab-weld kev kho mob, suav nrog kev kho cua sov, sib tsoo, thiab polishing, kom ntseeg tau qhov seamless thiab corrosion- tiv taus nto.
3. Kev kho deg
- Stainless hlau ERW yeeb nkab muaj qhov polished nto, ua rau nws zoo nkauj thiab haum rau kev lag luam xws li kho vaj tse vaj tse thiab tshuaj.
- Peb muab cov qib polishing sib txawv, suav nrog 180 #, 240 #, 320#, lossis iav polishing. Rau kev siv huv huv, peb muab electropolishing.
4. Kev Pabcuam Customization
- TORICH muab cov kev pabcuam sizing customized, ntau yam kev kho mob saum npoo, thiab kev ua tiav cov kev xaiv xws li beveling, tiaj kawg, thiab threading kom tau raws li cov kev xav tau ntawm ntau yam kev lag luam.
- Peb kuj tuaj yeem ua dabtsi yog khoov, txiav, drilling, thiab grooving raws li qhov project drawings. Cov ntaub ntawv stainless hlau tsim nyog tuaj yeem muab tau raws li cov neeg siv khoom thov.

FAQ
Q: Yuav ua li cas txhim khu kev qha cov welds ntawm ERW polished raj?
A: Peb cov kav dej yog tsim los siv cov khoom siv hluav taws xob siab tshaj vuam (ERW) tshuab. Cov welds yog tag nrho fused, kev ntxhov siab -relived, thiab polished. Peb kuj tseem ua qhov tsis yog -kev kuaj kev puas tsuaj (UT/RT) thiab kuaj hydrostatic los xyuas qhov zoo ntawm cov vuam.
Q: Kev kho deg puas tuaj yeem kho tau?
A: Yog. Peb muab ntau yam polished nto tiav kom tau raws li qhov yuav tsum tau ua, suav nrog 180 #, 240 #, 320 #, thiab daim iav polishing. Tsis tas li ntawd, passivation, pickling, lossis electrochemical polishing kev kho mob tuaj yeem siv los txhim kho corrosion kuj thiab cov qauv kev nyiam huv rau cov zaub mov, tshuaj, lossis tshuaj lom neeg kev lag luam.
Q: Koj puas muab cov ntaub ntawv zoo thiab cov ntaub ntawv xeem dab tsi?
A: Peb muab cov ntaub ntawv pov thawj hauv Hoobkas (EN 10204 3.1 / 3.2), hydrostatic thiab flattening/bending test reports, intergranular corrosion (ASTM A262) test reports, ultrasonic test reports, etc.
