LSAW Submerged Arc welding Carbon Steel Paipu no ka hoʻohana ʻana i ka pila
ʻO ka paipu kila LSAW (Longitudinally Submerged Arc Welding i hoʻopau ʻia e like me LSAW) he huaʻōlelo ʻoihana no ka paipu kila LSAW.Hoʻohana ʻo ia i hoʻokahi pā waena a me ka manoanoa e like me ka mea maka, a kaomi ʻia ka pā kila ('ōwili ʻia) i loko o kahi mold a i ʻole ka mīkini hana i loko o kahi pahu pahu.ʻO ke ʻano kuʻikuʻi arc submerged a hoʻonui ʻia ke anawaena e hana i nā paipu.
- Mea o LSAW Steel Paipu
Paipu Kūlana API 5L PSL1/PSL2 Gr.A,Gr.B,X42,X46,X52,X56,X60,X65,X70 ASTM A53 ASTM 572 ASTM A252 AN/NZS 1163 AN/NZS 1074 EN10219-1 EN10217-1 Nui OD: 219mm-1625mm WT: 7-50mm LOA: 5.8/6/11.8/12m
Nā noi:
Hoʻohana ʻia ka paipu LSAW no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa a i ʻole ka petroleum kiʻekiʻe a i ʻole ke kinoea maoli a hiki ke hoʻohana nui ʻia i nā kākoʻo a i ʻole nā kumu.
Ma muli o kona pono o ka hilinaʻi kiʻekiʻe a me ka hana palekana, ua hoʻohana nui ʻia ka paipu LSAW i nā ʻenehana pipeline a me ke kūkulu ʻana, ʻoiai ma lalo o ke kūlana koʻikoʻi loa, a hiki ke hoʻohana ʻia i ka ʻenekinia o ka ʻoihana kemika, ka mana uila, ka irrigation, ke kūkulu ʻana a me ka piling. etc.
LSAW paipu no ka aila a me ke kinoea paipu
ʻO ka pōmaikaʻi no ke ʻano LSAW ʻo ia ka mea hiki iā lākou ke hana i ka mānoanoa o ka pā mānoanoa o nā paipu, ka lōʻihi a hiki i 120 mm.
ʻO nā hiʻohiʻona nui o ka paipu kila LSAW:
1) Loaʻa i ka paipu kila he weld longitudinal, a ua hoʻopili ʻia nā weld i loko a me waho e ka wili arc submerged.
2) Ma hope o ka hoʻonui ʻia ʻana o ka mechanical, ʻo ke koʻikoʻi o loko o ka paipu kila he liʻiliʻi a hoʻohele like ʻia, hiki ke pale pono i ke koʻikoʻi o ka corrosion cracking, he kiʻekiʻe kiʻekiʻe ka pololei, a he kūpono no ka hana kuʻi ʻana ma ka pūnaewele.
3) Hoʻohana ʻia ke kaʻina hana hoʻoheheʻe mua a me ka hoʻopau ʻana i ke kaʻina hana kuʻi, paʻa ke kaʻina hana kuʻi, a kiʻekiʻe ka maikaʻi o ka wili.
4) He mea maʻalahi ka welding seam e ʻike i ka ʻike kīnā ʻole i ka hana hana a me ka ʻike kīnā ʻole i ke kula i ka wā e hoʻohana ai.
5) He nui ka laulā o nā kiko'ī huahana, hiki ke hana i nā paipu kila me ka li'ili'i li'ili'i a me ka mānoanoa o ka pā nui a me ka nui a me ka mānoanoa pā nui.
