Ezweni elihlala lishintsha lokwakha kanye nezicelo zezimboni, amapayipi ensimbi angenamthungo abe yingxenye ebalulekile ngenxa yokusebenza kwawo okumangalisayo kanye nokuthembeka. Lawa mapayipi asetshenziswa kabanzi ezimbonini ezahlukahlukene, njenge-petrochemical, ukukhiqizwa kukagesi, kanye nokukhiqiza, ngenxa yesakhiwo sawo esingenamthungo kanye nezakhiwo zawo ezingavamile.

II-ASTM A335 P5, P9, kanye namapayipi ensimbi angenamthungo e-P11 ayizinga elifunwa kakhulu aziwa ngokumelana kwawo nokushisa okuphezulu kanye nokucindezela. Lawa mapayipi asetshenziswa kakhulu ezindaweni zokuhluza, ezindaweni zokushintshanisa ukushisa, kanye nasezitshalweni zamandla, lapho edlala khona indima ebalulekile ekuthuthweni koketshezi olushisayo namagesi ngokuphepha nangokusebenza kahle.

Ngakolunye uhlangothi, amapayipi angenamthungo ensimbi yekhabhoni, njengeI-ASTM A106namapayipi ebhoyila afanaI-GB 8162 10#, aziwa ngezinhlelo zawo ezijwayelekile. Amapayipi e-ASTM A106 asetshenziswa kabanzi ezinhlelweni zokucindezela okuphansi nokuphakathi njengokufaka amapayipi, kanti i-GB 8162 10# isetshenziswa kabanzi ezinhlelweni zokucindezela okuphansi nokuphakathi.amashubhu ebhoyilazithandwa kakhulu ezimbonini ezahlukahlukene ngenxa yekhono lazo lokubekezelela amazinga okushisa aphezulu kanye nokucindezela, okwenza zibe zilungele ukufakwa kwamabhoyila.

Inqubo yokukhiqiza engenamthungo ithuthukisa amandla ala mapayipi futhi isuse izindawo ezibuthakathaka, okwenza angathinteki kalula ekuvuza nasekuqhumeni ngaphansi kwezimo zokucindezela okuphezulu. Ngaphezu kwalokho, ubuso bawo obubushelelezi bangaphakathi busiza ukugeleza koketshezi okungavimbelwe, kunciphisa ukulahleka kwamandla ngesikhathi sokuthuthwa.

Njengoba isidingo sezixazululo zamapayipi eziqinile nezisebenzayo siqhubeka nokukhula, ukusetshenziswa kwamapayipi ensimbi angenamthungo i-A335 P5, P9, P11, ASTM A106, kanye ne-GB 8162 10# kulindeleke ukuthi kukhule kakhulu ezimbonini emhlabeni jikelele. Abakhiqizi kanye nabasebenzisi bokugcina bayaqhubeka nokuqaphela ukubaluleka kwala mapayipi ensimbi angenamthungo ekuqinisekiseni impumelelo kanye nobude bemisebenzi yabo.
