Spiral Welded Steel Pipes Specifications and Standards
Nā kikoʻī:ʻO ke anawaena o waho 219mm a 3000mm; Mānoanoa sch40, sch80, sch160; ʻO ka lōʻihi 5.8m, 6m, 12m a i ʻole maʻamau
Papa:Hiki ke hana ʻia nā paipu SSAW ma nā māka like ʻole, me nā kikoʻī API 5L e like me Grade B, X42, X52, X60, X65, X70, a me X80.
Nā Kūlana:Hana maʻamau e like me nā kūlana e like me API 5L, ASTM A252, a i ʻole nā mea kikoʻī e pili ana i ka noi.
API 5L: Hoʻopuka ʻia kēia maʻamau e ka American Petroleum Institute a kuhikuhi i nā koi no ka hana ʻana i ʻelua pae kikoʻī o nā huahana (PSL 1 a me PSL 2) o nā paipu kila maʻemaʻe a welded no ka hoʻohana ʻana i nā ʻōnaehana kaʻa pipeline i ka ʻenehana a me nā ʻenehana kūlohelohe. .
ASTM A252: Ua hoʻopuka ʻia kēia maʻamau e ka American Society for Testing and Materials a uhi ʻia nā puʻu paipu kila cylindrical paia i loko o ka pahu kila ma ke ʻano he lālā lawe ukana mau a i ʻole he pūpū e hana ai i nā puʻupuʻu paʻa.
SSAW Spiral Welded Steel Pipe Surface Coating
3-Layer Polyethylene (3LPE) Ka uhi:Aia kēia uhi i kahi papa epoxy i hoʻopaʻa ʻia, kahi papa hoʻopili, a me kahi papa polyethylene. Hāʻawi ia i ke kūpaʻa corrosion maikaʻi loa a hoʻohana pinepine ʻia no nā pipelines i nā wahi paʻakikī.
Ka uhi ʻana o Fusion-Bonded Epoxy (FBE):Hāʻawi ka FBE coating i ke kūpaʻa kemika maikaʻi a kūpono i nā noi ma luna a me lalo.
uʻi:ʻO ke kaʻina hana galvanizing e pili ana i ka hoʻopili ʻana i kahi uhi zinc pale i ka paipu kila e hāʻawi i ke kūpaʻa corrosion. Hoʻokomo ʻia ka paipu kila weld spiral i loko o ka ʻauʻau o ka zinc hehee, kahi i hoʻopaʻa ʻia me ke kila, e hana ana i kahi uhi paʻa a me ka corrosion. He kūpono ka hoʻoheheʻe wela wela no ka hoʻohana ʻana i loko a me waho a hāʻawi i ka pale maikaʻi loa i ka ʻōpala a me ka ʻino.
Nā Paipu ʻAi ʻApi
Kaʻaila ʻaila a me ke kinoea:Hoʻohana nui ʻia no ka lawe ʻana i ka ʻaila maʻemaʻe, ke kinoea maoli, a me nā huahana ʻaila ʻē aʻe ma kahi lōʻihi.
Māhele Wai:He kūpono no nā paipu wai ma muli o ko lākou kūpaʻa a me ke kūpaʻa ʻana i ka corrosion.
Nā mea hana hale:Hoʻohana ʻia ma ke kūkulu ʻana no ke kākoʻo ʻana, e like me nā alahaka, nā hale, a me nā papahana ʻoihana ʻē aʻe.
ʻO ka nānā ʻana a me ka hoʻokele maikaʻi ʻana i nā paipu kalapona i hoʻopaʻa ʻia
Nānā Manaʻo:Nānā ʻia nā paipu no ka hoʻokō ʻana i ke anawaena, ka mānoanoa o ka paia, a me nā kikoʻī o ka lōʻihi.
Hoʻāʻo Mechanical:Hoʻāʻo ʻia nā paipu no ka ikaika tensile, ka ikaika e hāʻawi ai, elongation, a me ka paʻakikī e hōʻoia i ka hoʻokō ʻana i nā kūlana i koi ʻia.
ʻO ka hoʻāʻo hoʻopōʻino ʻole:
Ultrasonic Testing (UT): Hoʻohana ʻia no ka ʻike ʻana i nā hemahema o loko o ka weld seam.
ʻO ka hoʻāʻo Hydrostatic: Hoʻopili ʻia kēlā me kēia paipu i ka hoʻāʻo hydrostatic pressure e hōʻoia i hiki iā ia ke mālama i nā kaomi hana me ka ʻole o ka hū.
Hoʻopaʻa a me ka lawe ʻana i nā paipu kalapona ʻāwili ʻia
Nā kikoʻī kikoʻī: i loko o nā pūʻolo hexagonal kūpono i ke kai i hoʻopaʻa ʻia e nā ʻāpana kila, Me ʻelua maʻa nylon no kēlā me kēia pūpū.
Delivery Details : Ma muli o ka QTY, maʻamau hoʻokahi mahina.
