PALAPALA HUA LAP

Pono ka ʻāpala hui pū ʻelua i ʻelua ʻāpana paipu no kēlā me kēia ʻaoʻao o ka hoʻohui flanged, kahi stub a me kahi flange hope.Hoʻopili ʻia ka flange hope ʻoluʻolu ma luna o ke anawaena o waho o ka stub welau, kahi i hoʻopili ʻia i ka paipu.ʻAʻole i hoʻopili ʻia ka flange backing i ka paipu, a hiki ke hoʻololi ʻia, ʻoi aku ka maikaʻi i ka wā e pono ai ke kuhikuhi ʻana i nā flanges i ka wā o ke kūkulu ʻana.

Eia kekahi, no ka mea, ʻaʻole pili ka flange hope me ka wai kaʻina hana, hiki ke hana ʻia me kahi mea ʻoi aku ka pale ʻana i ka corrosive.No ka laʻana, inā he ʻino ke kaʻina hana a koi ʻia ka paipu me ke kila kila, e like me ka ASTM A312 TP316L, a laila pono e hana ʻia ka stub hope me SS 316L;akā naʻe, hiki ke hana ʻia ka flange kākoʻo me ka ASTM A105 maʻalahi.

ʻAʻole ikaika kēia ʻano o ka hoʻohui ʻana e like me ka ʻāʻī weld akā ʻoi aku ka maikaʻi ma mua o ka wili ʻana, ka weld socket, a me ka hoʻoheheʻe ʻana i nā pili;akā naʻe, ʻoi aku ka pipiʻi o ka hoʻokō ʻana, no ka mea, pono ia i ka weld butt penetration piha a koi i ʻelua ʻāpana.

HOPE KAHIKI

E hoʻohana mau ʻia kahi Stub End me kahi lepa Hui Lap, ma ke ʻano he lepa hope.

Hoʻohana ʻia kēia mau pili flange, i nā noi haʻahaʻa a me nā noi koʻikoʻi ʻole, a he ala haʻahaʻa ia o ka flanging.
I loko o kahi ʻōnaehana paipu kila kila, no ka laʻana, hiki ke hoʻohana ʻia kahi flange kila carbon, no ka mea ʻaʻole lākou i hui pū me ka huahana i ka paipu.

Loaʻa nā Stub Ends ma kahi kokoke i nā anawaena paipu a pau.Ua wehewehe ʻia nā ʻāpana a me nā ʻae ʻana i ka maʻamau ASME B.16.9.Hōʻike ʻia ʻo Stub Ends (pono) i ka MSS SP43.

POMAIKAI O LAP JOINT FLANGE

• ʻO ke kūʻokoʻa e wili a puni ka paipu e hoʻomaʻamaʻa i ka hoʻopaʻa ʻana o nā puka kīʻaha flange kū'ē.
• ʻO ka loaʻa ʻole o ka hoʻopili ʻana me ka wai i loko o ka paipu e ʻae pinepine i ka hoʻohana ʻana i nā flanges kila carbon inexpensive me ka paipu pale corrosion.
• I loko o nā ʻōnaehana e ʻā a ʻāʻī koke ʻia, hiki ke hoʻopakele ʻia nā flanges no ka hoʻohana hou ʻana.
