Mpweya wopanda msoko wa chitsulo chopanda mpweya muyezo

Chitoliro chachitsulo chopanda msoko cha kabonimiyezo ndi gawo lofunika kwambiri pakuwonetsetsa kuti mapaipi awa ndi abwino, akugwirizana, komanso otetezeka pa ntchito zosiyanasiyana. Miyezo iyi imapereka chitsogozo kwa opanga, ogulitsa ndi ogula kuti atsimikizire kuti mapaipi akukwaniritsa zofunikira zinazake komanso kutsatira malamulo amakampani.

Chimodzi mwa miyezo yodziwika bwino ya chitoliro chachitsulo chopanda mpweya ndiASTM A106/A106Mmuyezo. Yopangidwa ndi American Society for Testing and Materials (ASTM), muyezo uwu umalongosola zofunikira za chitoliro chachitsulo cha kaboni chopanda msoko kuti chigwiritsidwe ntchito kutentha kwambiri. Umakhudza kukula kwa chitoliro cha NPS 1/8 mpaka NPS 48 (DN 6 mpaka DN 1200) ndi makulidwe a makoma monga momwe zafotokozedwera mu ANSI B36.10.

Kupatula apo, muyezo wa chitoliro cha chitsulo chosasunthika cha kaboni umaphatikizapo API 5L,ASTM A53, ASTMA179,ASTM A192,ASTM A210/SA210, ASTM A252BS EN10210,JIS G3454ndi JIS G3456.

Kuphatikiza apo, muyezowu umaphatikizapo zofunikira pa mayeso osawononga, monga kuyesa kwa ultrasound, kuyesa kwa eddy current kapena kuyesa kwa hydrostatic, kuti zitsimikizire kuti mapaipi ndi olimba. Umakhudzanso zinthu zosiyanasiyana kuphatikizapo kulemba, kulongedza ndi zofunikira pa satifiketi.

Mwachidule, miyezo ya mapaipi achitsulo chopanda mpweya, monga ASTM A106/A106M, imapereka malangizo ofunikira popanga, kuyesa, ndi kuwongolera khalidwe la mapaipi awa. Kutsatira miyezo iyi kumatsimikizira kuti mapaipi akukwaniritsa zofunikira, magwiridwe antchito ndi zofunikira zachitetezo, ndikuwonjezera kudalirika kwawo komanso kuyenerera kwa mafakitale osiyanasiyana.
