Kwihlabathi elihlala litshintsha lezicelo zokwakha nezemizi-mveliso, iipayipi zentsimbi ezingenamthungo ziye zaba yinxalenye ebalulekileyo ngenxa yokusebenza kwazo okugqwesileyo kunye nokuthembeka kwazo. Ezi pipes zisetyenziswa kakhulu kumashishini ahlukeneyo, afana ne-petrochemical, ukuveliswa kwamandla, kunye nokuveliswa, ngenxa yesakhiwo sazo esingenamthungo kunye neempawu zazo ezibalaseleyo.

II-ASTM A335 P5, P9, kwaye iipayipi zentsimbi ezingenamthungo ze-P11 zifunwa kakhulu ngenxa yokumelana kwazo nobushushu obuphezulu kunye noxinzelelo. Ezi payipi zisetyenziswa kakhulu kwiindawo zokucoca, kwiindawo zokutshintsha ubushushu, nakwizityalo zamandla, apho zidlala indima ebalulekileyo ekuthuthweni kolwelo olushushu kunye neegesi ngokukhuselekileyo nangokufanelekileyo.

Kwelinye icala, imibhobho engenamthungo yentsimbi yekhabhoni, efanaI-ASTM A106kunye neetyhubhu zebhoyila ezifanaGB 8162 10#, ziyaziwa ngezicelo zazo ezisetyenziswa ngokubanzi. Iipayipi ze-ASTM A106 zisetyenziswa kakhulu kwizicelo ezinoxinzelelo oluphantsi noluphakathi ezifana nepayipi, ngelixa i-GB 8162 10#iityhubhu zebhoyilaZithandwa kakhulu kumashishini ahlukeneyo ngenxa yokukwazi kwazo ukumelana namaqondo obushushu aphezulu kunye noxinzelelo, nto leyo ezenza zilungele ukufakwa kweebhoyila.

Inkqubo yokuvelisa engenamthungo inyusa amandla ezi mbhobho kwaye isusa iindawo ezibuthathaka, nto leyo eyenza zingabi sengozini yokuvuza nokugqabhuka phantsi kweemeko zoxinzelelo oluphezulu. Ukongeza, umphezulu wazo othambileyo wangaphakathi unceda ukuhamba kolwelo ngaphandle kokuphazamiseka, nto leyo enciphisa ukulahleka kwamandla ngexesha lokuthuthwa.

Njengoko imfuno yezisombululo zemibhobho ezihlala ixesha elide nezisebenzayo iqhubeka nokukhula, ukusetyenziswa kwemibhobho yentsimbi engenamthungo i-A335 P5, P9, P11, ASTM A106, kunye ne-GB 8162 10# kulindeleke ukuba kukhule kakhulu kumashishini kwihlabathi liphela. Abavelisi kunye nabasebenzisi bokugqibela baya beqonda ngakumbi ukubaluleka kwale mibhobho yentsimbi engenamthungo ekuqinisekiseni impumelelo kunye nobude bexesha leeprojekthi zabo.
