Introduction to Shandong Kungang Spiral Pipe
Hana ʻia ka paipu spiral ma ka ʻōwili ʻia ʻana o ke kila kalapona kalapona haʻahaʻa a i ʻole ka ʻili kila haʻahaʻa haʻahaʻa i loko o kahi pahu hakahaka e like me kekahi kihi helical (i kapa ʻia ʻo ka angle hoʻokumu), a laila hoʻopaʻa i nā hili paipu. Hiki ke hana ʻia me kahi ʻāpana liʻiliʻi. Hōʻike ʻia kāna mau kikoʻī e ke anawaena o waho * ka mānoanoa pā. Pono ka paipu welded e hōʻoia i ka hoʻāʻo hydraulic, ka ikaika tensile o ka weld a me ka hana kuʻi anu e pono e hoʻokō i nā lula.
Ma ke ʻano o ke kaʻina hana kuʻi, ʻo ke ʻano o ka hoʻoheheʻe ʻana o ka paipu wiliwili wiliwili a me ka paipu kila kuʻi pololei, ʻo ia ka mea like, akā, ʻo ka paipu wili wili pololei e loaʻa i ka nui o nā welds T-shaped, no laila ua hoʻonui nui ʻia ka nui o nā hemahema. a me ke koena o ka welding ma ka T-like welds He nui ke koʻikoʻi, a ʻo ka weld metala pinepine i loko o ke koʻikoʻi koʻikoʻi ʻekolu, e hoʻonui ai i ka hiki o nā māwae. Eia kekahi, e like me nā lula ʻenehana o ka hoʻoheheʻe ʻana i ka arc submerged, pono i kēlā me kēia weld he wahi hoʻomaka arc a me kahi kiko hoʻopau, akā ʻaʻole hiki i kēlā me kēia paipu wili kuʻi pololei ke hoʻokō i kēia ʻano i ka wā e wili ai i kahi wili pōʻai, no laila e nui aʻe nā hemahema.
hoʻohana
Hoʻohana nui ʻia nā paipu spiral i ka ʻenekinia lako wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana mana uila, irrigation mahiʻai, a me ke kūkulu ʻana i ke kūlanakauhale. ʻO ia kekahi o nā huahana nui i hoʻomohala ʻia e ko mākou ʻāina. No ka lawe ʻana i ka wai: hoʻolako wai, hoʻokahe wai, ʻenekinia hoʻomaʻamaʻa wai, ka lawe ʻana i ka lepo, ka lawe ʻana i ka wai kai. No ka lawe kinoea: kinoea, mahu, liquefied petroleum gas. No nā kumu hoʻolālā: e like me nā paipu a me nā alahaka; na paipu no na uwapo, na alanui, na hale, na paipu pili moana, etc.
Nā Kūlana Huahana
Spiral seam submerged arc welded kila paipu SY5036-83 no ka pressurized kaʻa wai mea nui i hoʻohana 'ia no ka aila a me maoli kinoea pipelines; wiliwili ʻia ka paipu kila kiʻekiʻe alapine kiʻekiʻe SY5038-83 no ka lawe ʻana i ka wai i kaomi ʻia e ke kuʻi wāwae kiʻekiʻe. ʻO nā paipu kila i hoʻopaʻa ʻia no ka lawe ʻana i ka wai kaomi. ʻO ka paipu kila ka ikaika e hiki ai ke hoʻoikaika i ka ikaika, ka plasticity maikaʻi, a maʻalahi no ka wili a me ka hana ʻana; ʻO ke kuʻi ʻana o ka spiral arc welded steel pipe SY5037-83 no ka lawe ʻana i ka wai haʻahaʻa haʻahaʻa i hana ʻia e ka lua-ʻaoʻao ʻakomi hoʻoheheʻe arc a i ʻole hoʻokahi ʻaoʻao ʻaoʻao no ka wai, kinoea, ʻO nā paipu kila i hoʻopaʻa ʻia no ka lawe ʻana i nā wai haʻahaʻa haʻahaʻa. e like me ka ea a me ka mahu.
Hoʻokaʻawale ʻia nā kūlana maʻamau no nā paipu kila spiral i: SY/T5037-2000 (ke kūlana lawelawe, ʻike ʻia ʻo spiral seam submerged arc welded steel pipelines no nā pipeline transport fluid), GB/T9711.1-1997 (nā kūlana aupuni, pū kekahi. ʻike ʻia ʻo ka ʻoihana aila a me ka ʻoihana kaʻa kaʻa paipu kila) ʻO ka hapa mua o nā kūlana ʻenehana: A-grade steel pipe (GB/T9711.2 B-grade steel pipe me nā koi koʻikoʻi), API-5L (American Petroleum Institute, i kapa ʻia ʻo pipeline. paipu kila; i maheleia i elua pae: PSL1 a me PSL2), SY/T5040-92 (spiral submerged arc welded kila paipu no na puʻu).
