Ipayipi elingenamthungo linamandla okucindezela angcono, amandla aphezulu kunepayipi elishiselwe i-ERW. Ngakho-ke isetshenziswa kabanzi emishinini yokucindezela okukhulu, nasezimbonini ezishisayo, ezishisayo. Ngokuvamile umthungo wokushisela wepayipi lensimbi elishiselwe iphuzu elibuthakathaka, ikhwalithi ithinta ukusebenza okuphelele.

Ipayipi elingenamthungo vs ipayipi lensimbi elishiselwe:

1. Umehluko wokubukeka

Ipayipi lensimbi engenamthungo lisebenzise i-billet yensimbi njengempahla eluhlaza. Ukukhubazeka kwangaphandle kwe-billet akukwazi ukuqedwa inqubo yokugoqa okushisayo, ipholishwa kuphela ngemva kokuphela komkhiqizo. Enqubweni yokunciphisa udonga, isici singaqedwa kancane.

Ipayipi lensimbi elishiselwe elenziwa yikhoyili egoqiwe eshisayo njengempahla eluhlaza, izinga eliphezulu lekhoyili liyikhwalithi ephezulu yepayipi, futhi kulula ukuyilawula.Ingaphezulu lekhoyili eligoqiwe linezinga eliphezulu.
Ngakho-ke ikhwalithi yepayipi yensimbi ehlanganisiwe ingcono kakhulu kunepayipi lensimbi engenamthungo.

2. Umehluko wenqubo yokubumba
Ipayipi lensimbi elingenamthungo lingakhiwa kanye ngesikhathi sokugoqa.
Ipayipi lensimbi elishiselwe lenziwa ngomugqa wensimbi noma ipuleti lensimbi, ngokugoba kanye nezinqubo ezihlukene zokushisela.

3. Ukusebenza kanye nokusetshenziswa
Ipayipi lensimbi elingenamthungo linamandla okucindezela angcono, amandla aphakeme kunepayipi elishiselwe i-ERW. Ngakho-ke isetshenziswa kabanzi emishinini yokucindezela okukhulu, nasezimbonini ezishisayo, ezishisayo.
Ngokuvamile umthungo wokushisela wepayipi lensimbi elishiselwe iphuzu elibuthakathaka, ikhwalithi ithinta ukusebenza okuphelele.

Ngokuvamile, amapayipi ensimbi ashiselwe angakwazi ukubamba ingcindezi yokusebenza engaphansi kuka-20% kunalawo angenamthungo. Lokhu kwethembeka kuyisici esiyinhloko esenza abantu bafune ipayipi lensimbi elingenamthungo. Eqinisweni, wonke amapayipi ezimboni enziwa ngamapayipi angenamthungo kuphela ngenxa yokuthi amapayipi athwala ukushisa okukhulu, amakhemikhali kanye nemishini. Amapayipi ashiselwe athandwa kakhulu ezimbonini ze-aerospace, zezimoto neze-electronics lapho isabelomali siphansi ngokuqhathaniswa, kanjalo nengcindezi yomsebenzi efakwa emapayipini.

4. Umehluko Wosayizi Abatholakalayo
Kwabaningi babakhiqizi bamapayipi ensimbi angenamthungo eShayina, bakhiqiza osayizi bangempela bamapayipi angenamthungo ubuningi be-OD ngamayintshi angu-20, 508 mm. Lapho ngokuvamile kuncane kuno-16 intshi, 406.4 mm, ngenxa yemikhawulo yemishini. Futhi uma iklayenti lingathanda ukuthenga ipayipi lensimbi elingenamthungo ngaphezu kosayizi abangenhla, kuzosetshenziswa imishini yokwandisa ukushisa. Kodwa ngokuvamile lolu hlobo olushisayo olunwetshiwe lwekhwalithi yepayipi lensimbi engenamthungo alikwazanga ukuqhathaniswa nepayipi lokuqala lensimbi elingenamthungo.

Ngokuphambene nalokho, ipayipi lensimbi elihlanganisiwe alinayo le mikhawulo, osayizi abatholakala ku-1-1/2 intshi 48.3mm kuya ku-100 intshi 2540 mm.

5.Inaniumehluko
Ngokuvamile izindleko zepayipi lensimbi engenamthungo ziphakeme kunamapayipi ensimbi ashiselwe, ngoba impahla eluhlaza, imishini yokukhiqiza kanye nezinqubo. Kodwa ngezinye izikhathi ngokucindezela kwemakethe, ipayipi elishiselwe libiza kakhulu, ngakho-ke uma uhlangabezana nalesi simo, ungangabazi ukuthenga ipayipi yensimbi engenamthungo ngezilinganiso ezifanayo.
