1. Nyob rau hauv tsos, qhov sib txawv ntawm seamless steel yeeb nkab thiab welded steel yeeb nkab yog hais tias muaj weld tuav nyob rau hauv lub puab phab ntsa ntawm cov yeeb nkab welded, thaum tsis muaj seamless steel yeeb nkab.
2. Lub siab ntawm cov yeeb nkab seamless siab dua, cov yeeb nkab welded feem ntau yog li 10 MPa, thiab tam sim no cov yeeb nkab welded tau ua tiav. Lub seamless steel yeeb nkab yog perforated nrog ib puag ncig cov yeeb nkab. Tsis muaj qhov sib txawv, welded yeeb nkab yog cov yeeb nkab steel uas ua los ntawm vuam steel phaj lossis steel sawb tom qab crimping thiab sib sau, thiab muaj ib qho zawj. Feem ntau, seamless kav yuav tiv taus siab dua.
3. Lub seamless steel yeeb nkab yog tsim nyob rau tib lub sijhawm thaum dov. Welded steel kav yuav tsum tau welded tom qab dov, feem ntau yog muab kauv vuam thiab ncaj welding. Piv nrog rau kev ua tau zoo, lub raj seamless zoo dua, thiab tau kawg tus nqi siab dua.
4. Welded yeeb nkab feem ntau ua tiav los ntawm txias dov, siab zaus vuam, sib sau thiab lwm yam txheej txheem. Nws yog ib hom sewn raj. Seamless steel yeeb nkab tau muab faib ua cov yeeb nkab kub dov thiab cov yeeb nkab txias txias, thiab cov yeeb nkab kub kub yog ua tiav los ntawm kev sib tsoo, drilling, dov, sib sau thiab lwm yam. Feem ntau, qhov loj-inch, tuab-walled seamless raj yog siv rau hauv cov duab no; Cov kav dej txias txias yog txias los ntawm cov raj khoob, cov khoom siv lub zog yog qhov tsawg, thiab cov khoom siv sab hauv thiab sab hauv yog du. Feem ntau me me txoj kab uas hla, nyias-walled seamless raj yog zoo li no.

Ib co xov xwm ntxiv:
Lawv puas yog cov tuam txhab lossis cov ntaub?
A: Peb yog Hoobkas.
Qhov nkag hauv pem teb yog dab tsi?
A: Feem ntau nws yuav siv sijhawm 5-10 hnub yog tias cov khoom muaj nyob hauv Tshuag. Los yog nws yog 15-20 hnub yog tias cov khoom tsis nyob hauv Tshuag, nws yog raws li candida.
Q: Koj puas muab cov kws qhia poj niam? Puas yog dawb lossis ntxiv?
A: Yog, peb tuaj yeem muab tus tswv dawb tab sis kuv tsis them tus nqi thauj khoom.
Q: Kuv puas tuaj yeem kho qhov khoom raws li kuv qhov kev xav tau?
A: tau kawg. Koj tuaj yeem muab qhov ntev, dav thiab tuab.
