L360 pipeline kila hana maʻamau pipeline lawe paipu
L360 Pipeline Steel, Ke kumu: API SPEC 5L-2011 (Pipeline Specification), hoʻomohala ʻia a paʻi ʻia e ka American Petroleum Institute, hoʻohana ʻia ma ka honua holoʻokoʻa.Pipepipe: No ka lawe ʻana i ka aila, ke kinoea a i ʻole ka wai mai ka lepo ma o nā paipu paipu i ka ʻoihana aila a me ke kinoea.ʻO ka paipu paipu i loko o ka paipu maʻemaʻe a me ka welded paipu ʻelua ʻano, ʻo ka ʻaoʻao o ka paipu he wēlau palahalaha, ka hopena wili a me ka hopena kumu;ʻO ke ʻano hoʻohui ʻo ia ka hoʻopau ʻana i ka welding, ka hoʻopaʻa ʻana i ka hoop, ka pilina socket a pēlā aku.ʻO ka mea nui o ka paipu ʻo B, X42, X46, X56, X65, X70 a me nā papa kila ʻē aʻe.Ua hala kā mākou hui i ka palapala hōʻoia API (API 5CT a me API 5L) i ʻAukake 2009.
L360 Pipeline Steel, API SPEC 5L GB/T9711.1 GB/T9711.2 Kina National Standard Application: Oxygen, wai a me ka aila lawe paipu i loko o ka aila a me ke kinoea oihana B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Me ka hooulu ana o ka pipeline kila papa enehana a me ka holomua o welded paipu hana, kuʻihao 'enehana, ka palapala noi laula o ka paipu me welded paipu i loko o ka mālie hoʻonui, o ka oi aku i loko o ka nui anawaena welded paipu papa laula pono oi maopopo, a me ke kumu kūʻai. welded paipu ua dominant i loko o ke kula o ka laina paipu, i kaupalena 'ia ka ulu ana o kuhiliʻole kila seamless kila laina paipu.I ka makahiki 2004, he 400,000 t ka hopena o ka pipeline seamless, ʻo X42-70 ka pae kila, a ʻo nā ʻano ʻano he paipu ma kahakai a me ka pipeline submarine.
ʻO ka hana ʻana o ke kila kila kiʻekiʻe pipeline apono i ka microalloying hoʻomehana hoʻomaʻamaʻa kaʻina hana, ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ke kila kila ma mua o ka paipu welded, a me ka hoʻomaikaʻi ʻana i ka pae kila, e like me X80 a ma luna o ka palena o ka paipu pipeline ma luna o ka carbon equivalent. , He paʻakikī ka hana maʻamau o ka paipu seamless e hoʻokō i nā koi o nā mea hoʻohana;Ke hana nei kēlā me kēia 12Cr1moV alloy pipe i nā hana noiʻi ʻepekema i mea e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion o kāna paipu pipeline a me ka hana paʻa i ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe.
