Ulwazi ngeeMpayiphu zeNsimbi eWelded ze-ASTM A252
I-ASTM A252 yinkcazo eqhelekileyo yeepayipu zentsimbi ezitshixiweyo nezingenamthungo. Igubungela ubukhulu bodonga obuqhelekileyo, umgangatho, kunye nohlobo lwentsimbi.
Iipayipu zentsimbi zinokudityaniswa okanye zingabi namthungo kwaye ziyafumaneka ngobubanzi obahlukeneyo kunye nobukhulu bodonga ukuze zilungele iimfuno ezahlukeneyo zokuthwala umthwalo. Zisetyenziswa rhoqo kwiiprojekthi zokwakha apho imeko yomhlaba ifuna inkxaso enzulu yesiseko, njengakwiindawo eziselunxwemeni, elunxwemeni lomlambo, okanye kwiindawo ezinomhlaba othambileyo okanye okhululekileyo.

Ulawulo loMgangatho lweePipe zeNsimbi eziWelding ze-ASTM A252
1) Ngexesha nasemva kwemveliso, abasebenzi abane be-QC abanamava angaphezu kweminyaka emi-5 bahlola iimveliso ngokungacwangciswanga.
2) Ilabhoratri evunyiweyo yesizwe eneziqinisekiso ze-CNAS
3) Uhlolo olwamkelekileyo oluvela kumntu wesithathu oqeshwe/ohlawulwe ngumthengi, ofana ne-SGS, i-BV.
4) Ivunyiwe yiMalaysia, iIndonesia, iSingapore, iiPhilippines, iOstreliya, iPeru kunye ne-UK. Sinezatifikethi ze-UL/FM, ISO9001/18001, kunye ne-FPC
