     X42I-SSAWumbhobholuhlobo lombhobho wegesi yendalo osetyenziswa kakhulu kwishishini leoyile negesi. Wenziwa kusetyenziswa inkqubo yokuwelda ye-arc engaphantsi komhlaba evelisa imibhobho esemgangathweni ophezulu nehlala ixesha elide. Umbhobho we-X42 SSAW unamandla aphezulu kunye neempawu zeekhemikhali ezibalaseleyo, nto leyo eyenza ukuba ufaneleke ngokufanelekileyo kwiimfuno ezifunekayo zothutho lwegesi yendalo. Ukumelana kwawo kakuhle nokugqwala kunye nokuqhekeka kwenza kube lukhetho lokuqala kwiiprojekthi zokwakha imibhobho.

     I-ASTM A139ngomnye umgangatho obalulekileyo kwiipayipi zegesi yendalo. Olu lwazi lugubungela umbhobho wentsimbi othe tye okanye ojikelezayo odityanisiweyo osetyenziselwa ukuhambisa iigesi, umphunga, amanzi kunye nezinye izinto ezilulwelo. Umbhobho we-ASTM A139 waziwa ngokuthembeka kwawo kunye nokusebenza kwawo ixesha elide phantsi kweemeko zokusebenza ezinzima kakhulu. Ezi payipi zenzelwe ukumelana noxinzelelo oluphezulu kunye nokuguquguquka kobushushu, nto leyo eyenza ukuba zilungele ukuhanjiswa kwegesi yendalo kunye nokusetyenziswa kokusasazwa kwayo.
