Hoʻopaʻa ʻia i ka ʻili o ka pāpaʻi ʻole - BS 4504

Hōʻike huahana

Pahee ma ka PapaUa kūpono ʻo Flange no ka hoʻopili ʻana i ka paipu kila me ke kaomi nominal ʻaʻole iʻoi aku ma mua o 2.5MPa.ʻO ka ili hoʻopaʻa ʻana o ka palahalaha weldedflangehiki ke hana ʻia i ʻano laumania, concave a me convex a me ka tenon ʻano ʻekolu.ʻOi aku ka nui o ka hoʻohana ʻana i ka flange wili paʻa paʻa.Hoʻohana nui ʻia ia i ka hihia o nā kūlana haʻahaʻa haʻahaʻa, e like me ka haʻahaʻa haʻahaʻa unpurified compressed ea a me ka haʻahaʻa haʻahaʻa circulating wai.ʻO kona pōmaikaʻi, ʻoi aku ka liʻiliʻi o ke kumukūʻai.

Loaʻa i ka flange welding flat kekahi mau koi ʻenehana a me nā ʻāpana i ka hana a me ka hoʻohana ʻana, a hana ʻia a hana ʻia e like me kekahi mau ʻano:
1. ʻO ka pā kila no ka hana ʻana i ka flange welding palahalaha e hele i ka ʻike kīnā kani ultrasonic me nā hemahema lamination e hōʻoia i ka maikaʻi a me ka hana.E hana ʻia a nānā ʻia e like me nā koi o ka maikaʻi i ʻōlelo ʻia e hōʻoia i ka paʻa kila i hana ʻia a hoʻohana ʻia ʻaʻohe qnā pilikia pili kino,
2. ʻO ka ʻili cylindrical, e ʻoki ʻia i loko o nā ʻāpana ma ka ʻaoʻao o ka ʻōwili ʻana o ke kila, i hoʻopaʻa ʻia a hoʻopaʻa ʻia i loko o ke apo a hana ʻia i apo ma ka ʻili o ke kila, ʻaʻole e hana pololei ʻia i loko o ka ʻāʻī e ka pā kila. i ka wā o ka hana ʻana i ka flange butt, make a kaʻina hana me kekahi ʻenehana
3. E wili ʻia ʻo Butt welding flange me kekahi kaʻina hana kuʻi.E hoʻohana ʻia ka weld penetration piha no ka weld butt o ke apo,
4. E ho'opili 'ia ka humuhumu ku'i 'ana o ke apo ma hope o ka weld wela wela a me ka 100x ray a i 'ole ka ultrasonic flaw detection, a 'o ka 'ike kīnā radiographic e ho'okō me nā koi pae II o JB4730.E hoʻokō ka ʻike ʻana i ka hewa kani kani me nā koi o ka pae muliwai o JB4730.ʻO ke ʻano hana kuʻi ʻana cLoaʻa nā kūlana welding a me nā ʻenehana no ka hana ʻana a me ka hana ʻana o ka flange e hoʻokō i nā kūlana hana a me nā koi.
ʻO ka flange welding flat he ʻano ʻāpana diski, ʻo ia ka mea maʻamau i ka ʻenehana pipeline.Hoʻohana ʻia nā flanges i ʻelua.I ka ʻenehana pipeline, hoʻohana nui ʻia nā flanges no ka pili paipu.Ma na hookomo like ole o na paipu e hoopili ia oʻO ka pā flange, hiki ke hoʻohana i ka pipeline haʻahaʻa haʻahaʻa, hiki ke hoʻohana ʻia ka flange wili no ke kaomi ma luna o 4 kg, a hoʻohui ʻia nā wahi hoʻopaʻa ma waena o ʻelua mau puʻupuʻu kuʻi, a laila hoʻopaʻa ʻia nā flanges me nā ʻokoʻa me nā bolts, dʻokoʻa ka mānoanoa a me ka hoʻohana ʻana i nā bolts like ʻole.
