ʻO ka paipu paipu: ʻo ka ʻaila, ke kinoea a i ʻole ka wai i unuhi ʻia mai ka lepo e lawe ʻia i ka ʻoihana ʻaila a me ke kinoea e ka pipeline pipe. ka hopena o ke kumu; ʻO ke ʻano pili ka hoʻopau ʻana i ke kuʻi ʻana, ka pilina kola, ka pilina socket a pēlā aku.
Pipeline paipu: ka aila, kinoea a wai paha i unuhiia mai ka lepo mai, ua laweia i ka aila a me ke kinoea oihana e pipeline pipe.Welded paipu ua pili ia e fused kuʻihao laina paipu, ma ka laulā ka lōʻihi lōʻihi, hiki ke māʻona i ka mea hoʻohana nuipa, akā paʻa. ʻAʻole maikaʻi e like me ka hui pū ʻana o ka paipu liʻiliʻi, akā ʻoi aku ka pōkole o ka lōʻihi o ka pahu seamless, ʻaʻole hiki ke hoʻomāʻona i ka mea kūʻai aku i ka hoʻohana ʻana i ka lōʻihi lōʻihi, ke hoʻohana nei ka mea kūʻai aku i ke kaʻina hana pono e hana. Hoʻohana ʻia ka hui pū ʻana. ʻO ka paipu paipu he ʻelua ʻano o ka paipu wili ʻole a welded, ʻo ka hopena o ka paipu he wēlau palahalaha, kahi wili a me kahi kumu kumu;
Me ka hooulu ana o ka pipeline kila papa enehana a me ka holomua o welded paipu hana, kuʻihao 'ike loea, i ka palapala noi o ka paipu me ka welded paipu i loko o hoʻomāhuahua ana, oi aku i loko o ka nui anawaena welded paipu papa laula ka pono o ka oi pulu, a me ka uku. kumu, 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.
API5L pipeline paipu hana i keia manawa e hoʻohana ana i ka microalloying mehana hoʻomaʻamaʻa kaʻina hana, kuhiliʻole kila seamless paipu hana kumu kūʻai mea nui kiʻekiʻe ma mua o ka welded paipu, a me ka hoʻomaikaʻi 'ana o ke kila kila, e like me X80 kila pae paipu ma ka palena o carbon equivalent, ka hana maʻamau. o seamless kila paipu mea paakiki e hoʻokō mea hoʻohana koi
