Emikhakheni yokuthuthwa kukawoyela negesi, amapayipi okuhambisa amanzi, kanye nezisekelo zezinqwaba zesakhiwo, amapayipi ahlanganisiwe anomphetho ongenakuguqulwa ngenxa yamandla awo avelele kanye nomnotho. Kubathengi bamaphrojekthi obunjiniyela, amagama athi "I-API ye-Spirally Welded Tube 5L"futhi"Ipayipi Lomthungo We-Helical API 5L" kuvame ukuvela ngokushintshana. Ngakho-ke, buyini ubudlelwano phakathi kwalokhu okubili, futhi kufanele kuqondwe kanjani izincazelo zabo zobuchwepheshe?
Eqinisweni, i-API 5L ye-Spirally Welded Tube kanye ne-API 5L ye-Helical Seam Pipe zichaza imibono emibili ehlukene yokuqamba amagama yomkhiqizo ofanayo. Eyokuqala igcizelela inqubo yokwakha "i-spiral welding", kanti eyesibili igcizelela isici sesakhiwo "se-spiral seams". Womabili abhekisela kumapayipi ensimbi anamandla aphezulu enziwe ngemichilo yensimbi noma imiqulu, agobile futhi asongwe abe yindilinga, bese ehlanganiswa ndawonye emithungweni ngezinqubo ezifana ne-submerged arc welding. Izindlela ezahlukene zokushisela - ikakhulukazi inqubo ye-submerged arc welding enezinhlangothi ezimbili - iqinisekisa amandla nokuqina komzimba wepayipi ngaphansi kwezimo zokuhamba ezicindezelayo.
Amapayipi ahlanganisiwe ahambisana nezindinganiso ze-API 5L anenzuzo yokukwazi ukukhiqiza imininingwane yobubanzi obukhulu ngendlela eguquguqukayo, futhi ubude bepayipi ngalinye bungenziwa ngokwezifiso ngokwezidingo zephrojekthi. Lokhu kunciphisa kakhulu inani lamajoyinti okushisela endaweni futhi kuthuthukisa ukusebenza kahle kokufakwa kwamapayipi. Kungakhathaliseki ukuthi yi-Spirally Welded Tube API 5L noma i-Helical Seam Pipe API 5L, inani lawo eliyinhloko lisekuhlinzekeni ngesisombululo esiphephile, esingabizi, nesithembekile samapayipi okuthuthwa amabanga amade.
I-Cangzhou Spiral Steel Pipe Group Co., Ltd. ingumkhiqizi ohamba phambili emkhakheni wamapayipi ensimbi ajikelezayo kanye nopende wamapayipi wokuvikela ukugqwala eShayina. Le fektri itholakala eDolobheni laseCangzhou, eSifundazweni saseHebei. Selokhu yasungulwa ngo-1993, inkampani yandise indawo yayo yaya kumamitha-skwele angu-350,000, inempahla eyizigidi ezingama-yuan ezingu-680 kanye nabasebenzi abangu-680. Leli qembu likhiqiza amathani angu-400,000 amapayipi ensimbi ajikelezayo minyaka yonke, anenani lomkhiqizo waminyaka yonke elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8. Imikhiqizo yalo isetshenziswa kabanzi kumaphrojekthi amakhulu engqalasizinda yamandla kokubili ekhaya nakwamanye amazwe.
Ukukhetha i-Cangzhou Spiral Steel Pipe Group kusho ukukhetha isisekelo sobuchwepheshe esineminyaka engaphezu kwengu-30 esizinikele ekhwalithini. Uma ungathanda ukwazi okwengeziwe ngamapharamitha okucaciswa kwe-Spirally Welded Tube API 5L kanye ne-Helical Seam Pipe API 5L, sicela uzizwe ukhululekile ukubuza nganoma yisiphi isikhathi.
