1. Ipayipi lensimbi elingenamthungo liwuchungechunge olude lwensimbi olungenayo imithungo eduze kwalo futhi linengxenye ephambanayo engenalutho. Isetshenziswa kabanzi njengepayipi lensimbi lokuthutha uketshezi. Uma iqhathaniswa nensimbi eqinile, ilula ngesisindo lapho ukugoba namandla okubamba kuyafana. Insimbi eyongayo enezingxenye eziphambanayo esetshenziswa kakhulu ekwenzeni izingxenye zesakhiwo nemishini, njengamashafu okushayela imoto, amapayipi okubhola kawoyela, amafreyimu amabhayisikili, nezikafula zensimbi ezisetshenziswa ekwakheni.

2. Ipayipi lensimbi elishiselwe ipayipi lensimbi elenziwe ngokushisela amapuleti ensimbi noma amapheshana ensimbi ngemva kokugoqwa nokwakhiwa. Inqubo yokukhiqiza amapayipi ensimbi ashiselwe ilula, enezinhlobonhlobo eziningi kanye nokucaciswa, ukutshalwa kwezimali okuncane kwemishini, nokusebenza kahle kokukhiqiza okuphezulu, kodwa amandla ayo ajwayelekile aphansi kunalawo amapayipi ensimbi angenamthungo. Ngokuthuthuka okusheshayo kokukhiqizwa okuqhubekayo kwensimbi ye-strip ephezulu kanye nokuthuthuka kobuchwepheshe bokushisela nokuhlola, ikhwalithi yama-welds iyaqhubeka nokuba ngcono, izinhlobonhlobo kanye nokucaciswa kwamapayipi ensimbi ashiselwe kuyanda usuku nosuku, futhi athathe indawo engenamthungo. amapayipi ensimbi emikhakheni eyandayo. Amapayipi ensimbi ashiselwe ahlukaniswe ngamapayipi ensimbi ahlanganisiwe asongelwe kanye namapayipi ensimbi ahlanganisiwe aqondile ngokusho kohlobo lwe-weld. .

Inqubo yokukhiqiza yepayipi yensimbi eqondile yomthungo ilula, izindleko eziphansi, intuthuko esheshayo, nokusebenza kahle kokukhiqiza okuphezulu. Amandla amapayipi ensimbi asontelwe ngokujwayelekile aphakeme kunalawo amapayipi ensimbi ashiselwe ngomthungo oqondile. Amapayipi ensimbi ahlanganisiwe anama-diameter amakhulu angakhiqizwa kusuka ku-billet emincane, futhi amapayipi ensimbi ahlanganisiwe anama-diameter ahlukene angabuye akhiqizwe kusuka kumabhilidi obubanzi obufanayo. Kodwa-ke, uma kuqhathaniswa namapayipi ensimbi othungayo obude obufanayo, ubude be-weld bukhuphuka ngo-30 ~ 100%, futhi isivinini sokukhiqiza siphansi. Ngakho-ke, amapayipi ensimbi ashiselwe ububanzi amancane ngokuvamile asebenzisa i-seam welding eqondile, kuyilapho amapayipi amakhulu ensimbi ashiselwe ngokuvamile asebenzisa i-spiral welding.
