    I-X42 spiral submerged arc welded pipe, eyaziwa ngokuba ngumbhobho odityanisiweyo we-arc, usetyenziswa ngokubanzi kuthutho lwe-oyile, igesi yendalo kunye namanzi.Imibhobho yenzelwe ukuhlangabezana neemfuno zomgangatho we-American Petroleum Institute (API) 5L, echaza ibakala lensimbi, ubukhulu bodonga kunye neemfuno zobugcisa kwiibhobho zetsimbi ezingenamthungo kunye ne-welded.KubaX42 SSAW umbhobho, usebenzisa i-polypropylene efakwe umbhobho inika iingenelo ezininzi.

    Umbhobho we-Helical Seam

    Okokuqala, i-polypropylene lined pipe inika ukuxhathisa okugqwesileyo, okubaluleke kakhulu kwizicelo apho imibhobho ibonakaliswe kwizinto ezinobungozi ezifana neoli, igesi yendalo kunye neekhemikhali ezahlukeneyo.Iipolypropylene liners zisebenza njengesithintelo esikhuselayo, siqinisekisa ixesha elide lombhobho kunye nokunyaniseka nakwiindawo ezinzima.

    Ukongeza, imibhobho efakwe i-polypropylene iyaziwa ngokugqitywa kwayo okugudileyo, okunciphisa ukukhuhlane kwaye ivumela ukuhamba kakuhle kwamanzi.Oku kubalulekile kwiinkqubo zemibhobho ye-X42 SSAW ethutha i-oyile, irhasi namanzi kwimigama emide.Umphezulu ogudileyo awunciphisi kuphela amandla afunekayo ukuthutha ulwelo, kodwa kwakhona ukuthintela ukuqokelelwa kwenkunkuma kunye nentlenga ngaphakathi kombhobho.

    Ukongeza koku, umbhobho owenziwe nge-polypropylene ulula kwaye kulula ukuyifaka, okwenza kube isisombululo esineendleko zokufakelwa kombhobho we-X42 SSAW.Ubume obulula bale mibhobho benza lula ukuphatha kunye nokuthutha, ukunciphisa ixesha lofakelo kunye neendleko zabasebenzi.Ukongezelela, ukukhululeka kofakelo kuqinisekisa ukuba amaxesha eprojekthi ahlangeneyo ngaphandle kokulibaziseka.

    Umbhobho we-SSAW

    ASTM A139 kunyeEN10219yimigangatho emibini edla ngokubhekiselwa kuyo ekuveliseni nasekulawuleni umgangatho wemibhobho yentsimbi, kuquka imibhobho ye-X42 SSAW.Le migangatho ichaza iimpawu zomatshini, ukubunjwa kweekhemikhali kunye neemfuno zokuvavanya kwipayipi yensimbi ukuqinisekisa ukuthotyelwa kwemimiselo yoshishino kunye neenkcukacha.Ngombhobho owenziwe nge-polypropylene, le migangatho kufuneka ilandelwe ukuqinisekisa ukusebenza kunye nokuthembeka kwizicelo zepayipi ze-X42 SSAW.

    Isishwankathelo, i-polypropylene efakwe umbhobho idlala indima ebalulekileyo kwizicelo zemibhobho ye-X42 SSAW, ngakumbi ngokwemigangatho ye-ASTM A139 kunye ne-EN10219.Ukunganyangeki komhlwa, ukuphela komphezulu ogudileyo, ubume obukhaphukhaphu, kunye nokuthotyelwa kwemigangatho yoshishino kubenza balungele imizi-mveliso eyahlukeneyo.Njengoko iteknoloji iqhubela phambili, iipayipi ezifakwe kwi-polypropylene kulindeleke ukuba ziphuhlise ngakumbi ukuhlangabezana neemfuno eziguqukayo zokwakhiwa kunye ne-oyile kunye negesi yegesi.
