ʻO ka wehewehe ʻana o ka welding flange

ʻO ka wehewehe ʻana o ka welding flange

1. Hoʻopili palahalaha: E weld wale i ka papa o waho, me ka ʻole o ka wili ʻana i ka papa o loko; Hoʻohana maʻamau i nā pipeline puʻupuʻu haʻahaʻa a me ka haʻahaʻa, ʻo ke kaomi nominal o ka pipeline e emi iho ma mua o 0.25 MPa. ʻEkolu ʻano o nā ʻili hoʻopaʻa no nā flanges wili palahalaha

ʻAno, concave convex type, a me mortise groove type, i waena o ka lubrication type i hoʻohana nui ʻia, a ʻo ke kumukūʻai hiki ke kūʻai ʻia me ke kumukūʻai kiʻekiʻe.

2. Butt welding: Pono e welded nā ʻaoʻao o loko a me waho o ka flange, ka mea maʻamau i hoʻohana ʻia i nā pipeline medium a me ke kiʻekiʻe. ʻO ke kaomi nominal o ka pipeline ma waena o 0.25 a me 2.5 MPa. Hoʻopaʻa i ka ʻili o ke kumu hoʻohui flange welded

Paʻakikī loa nā mea hana, no laila ʻoi aku ka kiʻekiʻe o nā kumukūʻai hana, nā ʻano hoʻonohonoho, a me nā kumu waiwai kōkua.

3. Socket welding: maʻamau hoʻohana ʻia i nā pipeline me ke kaomi nominal ma lalo o a i ʻole like me 10.0MPa a me ke anawaena nominal ma lalo a i ʻole like me 40mm.

4. Loose lima: Hoʻohana maʻamau ia i nā pipelines me ka haʻahaʻa haʻahaʻa akā corrosive media, no laila, ʻoi aku ka ikaika o kēia ʻano flange i ka corrosion kūʻē, a ʻo ka mea maka ke kila kila.

Hoʻohana nui ʻia kēia ʻano pili no ka hoʻopili ʻana i nā paipu hao hao, nā paipu lāʻau i hoʻopaʻa ʻia, nā paipu metala non-ferrous, a me nā kiwi flange, a hoʻohana pū ʻia nā pili flange no ka hoʻopili ʻana ma waena o nā mea hana a me nā flanges.
