ʻOkoʻa ma waena o Weld Neck Flange a me Slip On Flange
1. Nā ʻano weld like ʻole:
Hiki ke nānā ʻia ka radiographic no nā welds o ka ʻāʻī kuʻi ʻana o ka ʻāʻī, akā ʻaʻole no ka ʻāʻī kuʻihao palahalaha.ʻO ke ʻano hoʻoheheʻe ʻana o ka ʻāʻī a me ka paipu he circumferential weld, aʻo ke ʻano kuʻi ʻana o ka flange wili paʻa a me ka paipu he fillet weld.ʻO ke kuʻi kuʻi ʻana ʻo ia ka weld pōʻai pōʻai, a ʻo ka kuʻi ʻana palahalaha ʻelua mau welds circumferential fillet.ʻO ka ʻokoʻa ma waena o nā mea ʻelua, ʻo ka weld e hoʻopili ana i ka ʻāʻī a me ka nozzle no ka Class B seam, aʻo ka weld e hoʻopili ana i ka flange butt-weld neck a me ka nozzle no ka Class C seam.
2. Nā mea like ʻole:
Hana ʻia nā mea o ka ʻāʻī kuʻi ʻana i nā ʻāpana kila ma ka mīkini.ʻO ka mea o ka flange welding slip-on me ka ʻāʻī i hana ʻia me ka pā kila maʻamau me ka mānoanoa i koi ʻia ma o ka mīkini.
3. Nā kaomi inoa like ʻole:
ʻO ke kaomi nominal o ka ʻāʻī butt-wellding flange ʻo 1-25MPa, ʻoi aku ka kiʻekiʻe.ʻO ke kaomi nominal o ka flange welding ʻāʻī he 0.6-4MPa.Ke hoʻohālikelike ʻia me ka flange welding flat neck, ʻoi aku ka haʻahaʻa o kona pae kiʻekiʻe a ʻoi aku ka haʻahaʻa o kona hiki ke hoʻololi i ke kaomi
