Sisanda kutyikitya isivumelwano nomthengi waseIndiya kwiveki ephelileyo. Imveliso i-alloy seamless steel pipeI-ASTM A335 P11. Sine-inventri ethile yeemveliso ze-alloy, ngoko sinokufumana iimveliso zabathengi. Umthengi lo mbhobho usetyenziselwa ityhubhu ephothiweyo, ityhubhu ephothiweyo njengesixhobo sokutshintshiselana ngobushushu, ixesha elide lisebenza kwimeko yobushushu obuphezulu begesi, njengebhoyila yokutshintsha ubushushu kunye netyhubhu ephothiweyo kusetyenziswa imekobume embi, ubushushu obuphezulu kunye noxinzelelo oluphezulu kunye ne-corrosive. umoya, odinga ityhubhu ephothiweyo kufuneka ibe nesalathisi sokusebenza okuphezulu. Okufana nokusebenza kwe-Anti-corrosion, ukusebenza kwe-Anti-wear, ukuxhathisa ukudibanisa okuphantsi, Uzinzo oluPhezulu kunye nokukwazi ukulwa nothuthu.

SikwanjaloI-ASME A210(A210M) GrA1,GrC, umbhobho webhoyila kunye nombhobho webhoyila weflue, kubandakanywa ivault yokhuseleko kunye nombhobho we-strut kunye nombhobho omncinci wodonga olungenamthungo ophakathi wekhabhoni umbhobho wentsimbi yombhobho weheater.

ASME A179,ASMEA192 njalo njalo.
