Embonini kawoyela negesi, ukubaluleka kwesistimu yamapayipi ethembekile futhi ephumelelayo angeke kubekwe phansi.Izinto nezinqubo ezihlukahlukene zidinga ukuhanjiswa ngamapayipi, okwenza ukukhetha kwamapayipi kubaluleke kakhulu.Kunezinhlobo ezimbili eziyinhloko zamapayipi asetshenziswa kule mboni: amapayipi angenamthungo namapayipi ashiselwe.Kulesi sihloko, sizogxila ohlelweni lokukhiqiza kanye nokusetshenziswa kweI-API 5L PSL1&PSL2 GR.B X42 X46 X52 X60 X65 X70 amapayipi ensimbi ashiselwe i-arc longitudinal ngaphansi kwamanzi.
Inqubo yokukhiqiza yeamapayipi ashiselwekuhlanganisa ukuhlanganisa iziphetho ezimbili zomucu wensimbi noma ipuleti ukuze kwakheke isakhiwo esifana neshubhu.Enye yezindlela ezisebenza kahle kakhulu ezisetshenziselwa le nqubo i-longitudinal submerged arc welding (LSAW) inqubo.Amapayipi ensimbi e-LSAW abonwa ngamandla awo, ukuqina kwawo, nokunemba kobukhulu.I-Botop Steel, umkhiqizi ohamba phambili ozinze e-China, ugxile ekuhlinzekeniAmapayipi ensimbi e-LSAW, ekhiqiza amathani angaphezu kuka-200,000 ngonyaka.Lawa mapayipi atholakala kumabanga ahlukahlukene afana ne-GR.B, X42, X46, X52, X60, X65, kanye ne-X70 - anikeza inhlobonhlobo yokukhetha yezinhlelo zokusebenza ezahlukene.
IAmapayipi ensimbi e-LSAWekhiqizwa yi-Botop Steel isetshenziswa kakhulu embonini kawoyela negesi.Lawa mapayipi aklanyelwe ngokukhethekile ukumelana nokucindezela okuphezulu, izindawo ezibolayo, namazinga okushisa aphakeme.Ngamasayizi asuka ku-355.6 OD kuya ku-1500 OD nogqinsi ukusuka ku-8mm kuya ku-80mm, angakwazi ukubhekelela izinhlobonhlobo zezidingo.Ukwengeza, i-Botop Steel iqinisekisa ukubambelela ngokuqinile kumazinga omhlaba afana ne-ASTM, i-API, ne-DIN ngesikhathi senqubo yokukhiqiza.Lokhu kuqinisekisa ikhwalithi nokuthembeka kwemikhiqizo yabo, kunikeza amakhasimende ukuthula kwengqondo.
Ukuzibophezela kweBotop Steel kwikhwalithi kuboniswa futhi izitifiketi ezithile zokuhlola ezinikezwe umkhiqizo wabo ngamunye wamapayipi ensimbi we-LSAW.Konkeamapayipi kanye neshubhuimikhiqizo ihlinzekwa ngezitifiketi zokuhlola eziqondile ezingu-3.1, ngokuya nge-EN 10204. Lesi sitifiketi siqinisekisa ukuthi imikhiqizo ihlangabezana namazinga adingekayo kanye nokucaciswa kwayo, kunikeza amakhasimende isiqiniseko somkhiqizo onokwethenjelwa nosebenza kakhulu.
Ekuphetheni,I-API 5L PSL1&PSL2 GR.B X42 X46 X52 X60 X65 X70amapayipi ensimbi ensimbi ashiselwe i-arc longitudinal akhiwe kusetshenziswa indlela ye-LSAW anikeza isisombululo esithembekile nesiqinile embonini kawoyela negesi.I-Botop Steel, njengomkhiqizi othenjwayo kanye nesitoko, ihlinzeka ngezinketho eziningi ngokuya ngamabanga, osayizi, nogqinsi.Ukuzibophezela kwabo kwikhwalithi nokubambelela ezindinganisweni zamazwe ngamazwe kubenza babe abahlinzeki abathandwayo emakethe.
