Iko kukosha kwekukudziridza refuitudinal seam yakadzika-arc yakamonera pombi

Parizvino, mapuripi anonyanya kushandiswa kwenguva refu-refu mafuta uye gasi rekufambisa. Pippeline Steel pombi inoshandiswa mune refu-kureba pombi inonyanya kusanganisiraSpiral yakakundwa Arc yakavezwa masimbi pombiuye yakatwasuka seam kaviri-yakatsikwa yakanyorwa arc yakavezwa zvibayiro zvesimbi. Nekuti iyo Spiral yakakundwa Arc yeARC yakavezwa pombi yakagadzirwa nesimbi uye madziro ayo rusvingo ishoma, kuvandudzwa kwegiredhi giredhi kunogumira nekubatwa kwekurapa kwezvinhu zvinopesana. Mukuwedzera, pane zvimwe zvikanganiso zvekushayikwa kwekupfava zvakarukwa ARC yakavezwa pombi, yakadai selld weld, kushushikana kwakakura kushungurudzika uye kuvimbika kusarongeka kwekuvimbika kweWeld. Nezvinodiwa zvinowedzera zvemafuta uye gasi kutapurirana masimbi mapipi, ivo havachashandiswi munzvimbo dzine vanhu venzvimbo uye nzvimbo dzine nzvimbo dzakakwirira dzekuvimbika, uyeyakakura-dhayamita yakakwenenzverwa pombivari kutsiva zvishoma nezvishoma mapepa akasarudzika emapipi.

Nguva pfupi yadarika, China iri kukurumidza kukurumidza kukura kwemafuta uye gasi muEast China Gungwa. Nekuvandudzwa kwemafuta kushungurudzwa kwegungwa, pombi yakamiswa pamusoro pemauto ekumanikidzwa, simba rekubhururuka, uye chinhu chisina kusimba chinongedzo cheSpiral pombi. Kuti uvandudze iyo pombi yekufambisa yekufambisa uye simbisa iyo submarine pombi yekuvandudza yakananga kune gobvu madziro, iyo submarine pombi inonyanya kugamuchira pombi yakatwasuka. Naizvozvo, kana uchienzaniswa neyepombi yechipomba

Machina, kuvaka, indasitiri yemakemikari uye mamwe maindasitiri anoda zvakananga ma pipes. Parizvino, gomba remukati remagetsi chigaro chinokambaira mushure mekukoshesesa muindasitiri, iyo inoshandisa-kupedza nguva, kupedza nguva uye zvekutadza. Kana yakakwenenzverwa-yakakwenenzverwa seam yakachena Pipe inoshandiswa, ichave yakawanda hupfumi. Mukuwedzera, nekuda kwezvinodiwa zvehunyorwa zvekushandisa zveAnti-Flattening pombi dzakarongeka dzinoshandiswa pakuvaka pombi dzekuvaka; Yakatwasuka Pombi inotarisirwa zvakare kuti ishandiswe pombi dzemakemikari.
