Ivalvu yeBhola yePipeline yoMzimba eWelded ngokupheleleyo yoThumelo kunye noSasazo lweGesi yendalo eTshayina
Yintoni ivalvu yebhola yegesi yendalo?
I-NortechIvalve yeBhola edibeneyo epheleleyoIphuhliswe ngabasebenzi bobuchwephesha bobunjineli abavela kumzi-mveliso abanamava angaphezu kweminyaka engama-30 kuyilo nasekwenzeni ivalvu enoxinzelelo oluphezulu kunye nomgangatho wobugcisa wamva nje wamazwe ngamazwe. Ngenxa yeempawu ezikhethekileyo zevalvu yebhola engaphantsi komhlaba, amandla okunyamezela uxinzelelo lwepayipi, ukhuseleko, ipropati echasayo imozulu kunye nokuthembeka kwexesha elide kuyaqwalaselwa ngokupheleleyo xa kuyilwe.
Iimpawu eziphambili zevalvu yebhola yegesi yendalo
2. Ukumelana nokugqwala kunye nokumelana noxinzelelo lwe-sulfide
Isibonelelo esithile sokugqwala sigcinelwe ubukhulu bodonga lomzimba, xa kujongwa ukugqwala. Isiqu sentsimbi yekhabhoni, umngxuma osisigxina, ibhola, isihlalo kunye neringi yokugcina isihlalo zifakwa kwi-nickel plating yamakhemikhali ngokwe-ASME B733 kunye ne-B656. Ukongeza, izixhobo ezahlukeneyo ezichasene nokugqwala ziyafumaneka ukuze abasebenzisi bazikhethe. Ngokwesicelo sabathengi, izixhobo zevalvu zinokuhlangabezana neemfuno ze-NACE MR 0175/1S0 15156 okanye i-NACE MR 0103, kwaye ulawulo olungqongqo lomgangatho kunye nokuhlolwa komgangatho kufuneka kwenziwe ngexesha lenkqubo yokuvelisa ukuze kuhlangatyezwane ngokupheleleyo neemfuno kwimigangatho kwaye kuhlangatyezwane neemeko zenkonzo kwindawo yesulfurization.
3. Ulwakhiwo lweValve edibeneyo
Ngexesha lenkqubo yokwenziwa kwevalvu yebhola yombhobho edityanisiweyo ngokupheleleyo, umbhobho wotshintsho unokudityaniselwa kwivalvu yeziphelo zokuwelda. Umbhobho wotshintsho ungabonelelwa ngabasebenzisi okanye yi-NORTECH, ngokwesicelo sabasebenzisi. Nceda ubonise ububanzi kunye nobude bombhobho wotshintsho u-A xa ubeka ii-odolo.
4. Itywina lesiqu
Ukuqinisekisa ukuqina okuhle, isitywina se-stem esinee-layers ezintathu senzelwe ukuthintela ukuvuza kwiimeko ezahlukeneyo zokusebenza.
