Ipayipi Lensimbi Elishiselwe I-Cold Formed A252 Grade 1 For Structural Gas Pipelines
I-ASTM A252 iyindinganiso esungulwe kahle yepayipi lensimbi esetshenziswa ezinqwabeni zesisekelo, izinqwaba zamabhuloho, izinqwaba zezinsika kanye nezinye izinkambu zobunjiniyela. Lawa mapayipi ensimbi aklanyelwe ukumelana nezingcindezi eziphezulu futhi afanele ukusetshenziswa ezindaweni ezihlukahlukene ezidinga kakhulu. Eyethukubanda kwakheka ashiselwe kwesakhiwoamapayipi egesi akhiwe ngensimbi ye-A252 Grade 1, eyaziwa ngokuhlala isikhathi eside namandla ayo.

Ukwakhiwa kwethu kweshubhu lensimbi kusebenzisa indlela yokushisela ye-arc engaphansi kwamanzi ephindwe kabili, iqinisekisa izinga eliphezulu lokunemba kanye nekhwalithi kuwo wonke umkhiqizo. Le ndlela ihilela amapayipi ensimbi okushisela ngaphakathi nangaphandle, okwenza isibopho esiqinile. Umphumela uwumkhiqizo omelana nokugqwala futhi ofanele uhla olubanzi lwezinhlelo zokusebenza zezimboni nezokwakha.
Ipayipi lethu legesi elakhiwe ngendlela ebandayo elakhiwe ngendlela ebandayo liphinde lenzelwe ukuthi lihlangabezane nezidingo ezithile zezakhiwo ezishicilele ezichazwe kuzinga le-ASTM A252. Ngokwaleli zinga, ipayipi lethu lensimbi lihlukaniswe ngamabanga amathathu: IBanga loku-1, iBanga lesi-2 kanye neBanga lesi-3, ibanga ngalinye linikeza amazinga ahlukene wamandla nokuqina. Lokhu kwenza amakhasimende ethu akwazi ukukhetha ibanga elifanelana kangcono nezidingo zabo zohlelo lokusebenza nokusebenza kwazo.
Kungakhathaliseki ukuthi isetshenziswa njengezinqwaba zesisekelo sephrojekthi yokwakha noma njengengxenye yamabhilidi ebhuloho noma ama-pier, amapayipi ethu ensimbi akhelwe ukumelana nezinselele ezinzima kakhulu. Baletha ukusebenza okuthembekile nokuqina okuhlala isikhathi eside, okubenza bafaneleke ezinhlobonhlobo zezinhlelo zokusebenza zobunjiniyela nezokwakha.
Kafushane, ukubanda kwethu kwakha isakhiwo esishiselweamapayipi egesi, ekhiqizwe ngensimbi ye-A252 yeBanga loku-1 futhi yakhiwe kusetshenziswa indlela yokushisela i-arc engaphansi kwamanzi ephindwe kabili, iyisixazululo esinokwethenjelwa nesiphezulu sezinhlelo zokusebenza ezifunwayo. Lawa mapayipi ensimbi ahambisana nezindinganiso ze-ASTM A252 futhi aklanyelwe ukuhlangabezana nezidingo ezithile zempahla yemishini, iqinisekisa ukuthi ahlinzeka ngokusebenza okuphezulu nokuqina. Khetha ipayipi lethu lensimbi lephrojekthi yakho elandelayo futhi uthole umehluko ngekhwalithi nokuthembeka.
