Ipayipi lensimbi elingenamthungo liwuhlobo lwepayipi lensimbi elingenamthungo, futhi ukusebenza kwalo kuphakeme kakhulu kunokwepayipi elivamile lensimbi elingenamthungo, ngoba leli payipi lensimbi liqukethe i-Cr eyengeziwe, futhi ukumelana kwayo nokushisa okuphezulu, ukumelana nokushisa okuphansi nokusebenza kokumelana nokugqwala kungcono kune amanye amapayipi ensimbi angenamthungo. Okungenakuqhathaniswa, ngakho-ke amashubhu e-alloy asetshenziswa kakhulu ku-petroleum, amakhemikhali, amandla kagesi, i-boiler nezinye izimboni. Ishubhu lensimbi engenamthungo (Seamless Steel Tube) linengxenye engenalutho, umucu omude wensimbi ongenamajoyinti awuzungezile. Ipayipi lensimbi linengxenye engenalutho futhi lisetshenziswa kakhulu njengepayipi lokuthutha uketshezi, njengamapayipi okuthutha uwoyela, igesi yemvelo, igesi, amanzi kanye nezinto ezithile eziqinile. Uma kuqhathaniswa nensimbi eqinile njengensimbi eyindilinga, ipayipi lensimbi engenamthungo inamandla afanayo aguquguqukayo kanye ne-torsional kanye nesisindo esilula. Kuyinsimbi yengxenye yokonga futhi isetshenziswa kabanzi ekwenzeni izingxenye zesakhiwo nezingxenye zemishini, njengokuthuthwa kukawoyela. Ukwenza izingxenye zendandatho ngepayipi lensimbi elingenamthungo kungathuthukisa izinga lokusetshenziswa kwezinto, kwenze kube lula inqubo yokukhiqiza, konga izinto zokwakha kanye nesikhathi sokucubungula, njengezindandatho ezigoqayo, amasethi kajeke, njll., eziye zasetshenziswa kabanzi ekukhiqizeni amapayipi ensimbi. Ipayipi lensimbi elingenamthungo liphinde libe yinto ebaluleke kakhulu ezikhalini ezahlukahlukene ezijwayelekile, futhi umgqomo, umgqomo, njll. kumele wenziwe ngepayipi lensimbi. Ukwengeza, lapho ingxenye yendandatho ingaphansi kokucindezela kwe-radial yangaphakathi noma yangaphandle, amandla ayafana ngokuqhathaniswa. Ngakho-ke, amapayipi ensimbi amaningi angenamthungo angamapayipi ayindilinga.
