     Umbhobho ofakwe ipolypropyleneiye yaba yinxalenye ebalulekileyo yamashishini ahlukeneyo, ingakumbi kwicandelo lokwakha, ioyile negesi. Le mibhobho yaziwa ngokuqina kwayo okugqwesileyo, ukumelana nokugqwala, kunye nokukwazi kwayo ukumelana namaqondo obushushu aphezulu kunye noxinzelelo. Kule blog, siza kujonga ukubaluleka kwemibhobho ene-polypropylene kwizicelo zemibhobho ye-X42 SSAW ngokweI-ASTM A139kunye nemigangatho ye-EN10219.

    Umbhobho we-X42 spiral arc welded, okwaziwa ngokuba ngumbhobho we-arc welded ongaphantsi komhlaba, usetyenziswa kakhulu ekuthuthweni kweoyile, igesi yendalo kunye namanzi. Le mibhobho yenziwe ukuze ihlangabezane neemfuno zomgangatho we-5L we-American Petroleum Institute (API), ochaza umgangatho wentsimbi, ubukhulu bodonga kunye neemfuno zobugcisa zemibhobho yentsimbi engenamthungo nedibeneyo.Umbhobho we-X42 SSAW, ukusebenzisa umbhobho ofakwe i-polypropylene kunika iingenelo ezininzi.

    Umbhobho womthungo weHelical

    Okokuqala, umbhobho ofakwe i-polypropylene unika ukumelana okuhle nokugqwala, nto leyo ibaluleke kakhulu xa imibhobho ivezwa zizinto ezigqwala ezifana neoyile, igesi yendalo kunye neekhemikhali ezahlukeneyo. Ii-polypropylene liners zisebenza njengomqobo wokukhusela, ziqinisekisa ukuba imibhobho ihlala ixesha elide kwaye ithembekile nakwiindawo ezinzima.

    Ukongeza, imibhobho eneepolypropylene iyaziwa ngokugqitywa kwayo okugudileyo, okunciphisa ukungqubana kwaye kuvumela ukuhamba kakuhle kolwelo. Oku kubalulekile kwizicelo zemibhobho ye-X42 SSAW ezithutha ioyile, igesi kunye namanzi kumgama omde. Umphezulu ogudileyo awunciphisi nje kuphela amandla afunekayo ukuthutha ulwelo, kodwa uthintela nokuqokelelwa kwenkunkuma kunye nenkunkuma ngaphakathi kombhobho.

    Ukongeza koku, umbhobho ofakwe kwi-polypropylene ulula kwaye kulula ukuwufaka, nto leyo eyenza ukuba ube sisisombululo esingabizi kakhulu sokufakelwa umbhobho we-X42 SSAW. Ubunzima bale mbhobho buyenza lula indlela yokuphatha nokuthutha, bunciphisa ixesha lokufakela kunye neendleko zomsebenzi. Ukongeza, ukulula kokufakela kuqinisekisa ukuba amaxesha eprojekthi ayafezekiswa ngaphandle kokulibaziseka.

    Umbhobho we-SSAW

    I-ASTM A139 kunyeEN10219yimigangatho emibini edla ngokubhekiselwa kuyo kwimveliso kunye nolawulo lomgangatho weepayipi zentsimbi, kuquka iipayipi ze-X42 SSAW. Le migangatho ichaza iimpawu zoomatshini, ukwakheka kweekhemikhali kunye neemfuno zovavanyo lweepayipi zentsimbi ukuqinisekisa ukuthotyelwa kwemigaqo kunye neenkcukacha zoshishino. Kwipayipi eneepolypropylene, le migangatho kufuneka ilandelwe ukuqinisekisa ukusebenza kunye nokuthembeka kwizicelo zeepayipi ze-X42 SSAW.

    Ngamafutshane, ipayipi ene-polypropylene idlala indima ebalulekileyo ekusetyenzisweni kwepayipi ye-X42 SSAW, ngakumbi ngokwemigangatho ye-ASTM A139 kunye ne-EN10219. Ukumelana kwayo nokugqwala, ukugqitywa komphezulu okugudileyo, ubume bayo obulula, kunye nokuthobela imigangatho yeshishini kuyenza ibe yeyona ifanelekileyo kumashishini ahlukeneyo. Njengoko ubuchwepheshe buqhubeka buhambela phambili, kulindeleke ukuba ipayipi ene-polypropylene iphuhliswe ngakumbi ukuze ihlangabezane neemfuno ezitshintshayo zamashishini okwakha kunye neoyile negesi.
