Uyini umehluko phakathi kwepayipi lensimbi engenamthungo kanye nepayipi lensimbi elithungwe

(1) ipayipi lensimbi engenamthungo livamise ukugoqwa lisuka ku-carbon steel noma i-low-alloy structural steel, liwukusetshenziswa kwasekuqaleni kwempahla yepayipi lensimbi, indawo yalo ephambanayo inkulu, indawo yeyunithi engaphansi kwengcindezi incane.

(2) Amapayipi ensimbi athungelwe ngokuyinhloko asetshenziselwa ukuthutha uketshezi.Ngenxa yokukhiqiza kungenziwa i-welded, ngakho-ke izidingo zamandla ahlangene ziphezulu, nokuqinisekisa ukuthi i-joint inokumelana nokugqwala nokumelana nokushisa, njll.

(3) Ipayipi lensimbi engenamthungo lisetshenziswa ikakhulukazi ekukhiqizeni imishini ejwayelekile, uphethiloli, amakhemikhali, amandla kagesi, ukwakhiwa nezinye izimboni, ezisetshenziswa kabanzi.

(4) kusukela kunqubo yokukhiqiza, inqubo yokukhiqiza ipayipi lensimbi engenamthungo isithuthuke kakhulu, ipayipi lensimbi elithungwe lisebenzisa izindlela zenqubo ezilula.

(5) Ngokombono wokusetshenziswa, umehluko phakathi kwalokhu okubili awuningi, kodwa owokuqala usetshenziselwa ukuthutha uketshezi nezinye izinhlayiya eziqinile, lokhu kokugcina kusetshenziselwa ukuthutha uketshezi.
(6) Ngokombono wezinto ezibonakalayo, awukho umehluko ophawulekayo phakathi kwalokhu okubili, ikakhulukazi ngenxa yokuthi ipayipi lensimbi elingenamthungo elisetshenziswe endabeni liqukethe izinhlobonhlobo zezingxenye ze-alloy futhi liholela ekuhlukeni kwentengo.

(7) Ngokombono wokusetshenziswa, owokuqala usetshenziswa kakhulu ezintweni ezithwala imithwalo zezakhiwo namabhuloho othelawayeka wesitimela nezinye izinsiza;lesi sakamuva sisetshenziswa kakhulu ku-petroleum, amakhemikhali, amandla kagesi, ukukhiqizwa kwemishini nezinye izimboni.

(8) Ngokombono wezindleko, eyokuqala ingcono kuneyakamuva ngokwekhwalithi namanani.Umehluko phakathi kwepayipi lensimbi engenamthungo kanye nepayipi lensimbi elithungwe ungatholakala kulesi singeniso esingenhla: ipayipi lensimbi engenamthungo lisetshenziselwa ikakhulukazi ukuthutha uketshezi;futhi ipayipi lensimbi elithungelwe lisetshenziselwa ukuthutha uketshezi, okuqinile, njll.

Kodwa ngaphansi kwezimo ezifanayo ukusetshenziswa kwepayipi lensimbi elingenamthungo kungathuthwa uketshezi oluwububanzi obukhulu kanye nezinhlayiya ezithile eziqinile, futhi ohlelweni lwamapayipi ipayipi lensimbi elingenamthungo limelana nokugqwala kunepayipi lensimbi elithungo, ukuphila isikhathi eside kwesevisi;
