Trunnion Mounted Underground Fully Welded Ball Valve Kina Hana Hana
He aha ka pahu kinipopo Underground?
NortechPiha kinipopo Welded pihaua hoʻomohala ʻia e nā limahana ʻenehana ʻenehana mai ka hale hana me ka ʻoi aku o 30 mau makahiki i ka hoʻolālā ʻana a me ka hana ʻana i ka valve kiʻekiʻe a me ke kūlana ʻenehana hou loa o ka honua, ua hoʻohana nui ʻia no ka lawe ʻana i ka pipeline lōʻihi o ka ʻaila, ke kinoea maoli a me ka ʻōnaehana pipeline. ma na kulanakauhale.
ʻO nā hiʻohiʻona nui o Underground ball valve
1.lntegral Valve Kapili
Ua piha welded e forged steel.The forging materials are subjected to ultrasonic examination asme asme non-destructive examination(NDE) flaw detection requirements.The buttweld ending is subjected to particle penetration examination,RT services available.
2.Corrosion Kū'ē a me ka sulfide Stress Kū'ē
Ua mālama ʻia kekahi ʻāpana corrosion no ka mānoanoa o ka paia o ke kino, i ka noʻonoʻo ʻana i ka corrosion. ʻO ke kumu kila kalapona, ka lāʻau paʻa, ka pōleʻa, ka noho a me ke apo hoʻopaʻa noho i hoʻopaʻa ʻia i ka nickel plating e like me ASME B733 a me B656. Loaʻa nā mea i nā mea hoʻohana e koho. E like me ka noi a nā mea kūʻai aku, hiki i nā mea valve ke hoʻokō i nā koi o NACE MR 0175 / 1S0 15156 a i ʻole NACE MR 0103, a pono e hoʻokō ʻia ka mana koʻikoʻi a me ka nānā ʻana i ka maikaʻi i ka wā o ka hana ʻana. e hoʻokō pono i nā koi i nā kūlana a hoʻokō i nā kūlana lawelawe i ka sulfurization environment.
5. Noho noho
E like me ka noi a ka mea kūʻai aku, hiki ke hoʻolālā ʻia ka noho e like me DBB, DIB-1, DIB-2, e hālāwai me nā koi o nā kūlana hana like ʻole.
Noho DBB
Noho DIB-1
Noho DIB-2
ʻO ka ʻike loea o Underground ball valve
