ʻO ka paipu welded, ʻike ʻia hoʻi ʻo ka paipu kila welded, i hana maoli ʻia me ka pā kila a i ʻole ke kaula i wili ʻia ma hope o ka decoiling a me ka hana ʻana.Loaʻa ka maikaʻi o ka paipu kila Welded i ke kaʻina hana maʻalahi, ka hana kiʻekiʻe o ka hana ʻana, ʻoi aku ka nui o nā ʻano a me nā kikoʻī, a ʻoi aku ka liʻiliʻi o nā lako hana, akā ʻoi aku ka haʻahaʻa o kona ikaika ma mua o ka paipu kila seamless.Mai ka 1930s, me ka hoʻomohala wikiwiki ʻana o ka hana ʻōwili kiʻekiʻe kiʻekiʻe a me ka holomua o ka ʻenehana welding a me ka ʻenehana nānā ʻana, ua hoʻomaikaʻi mau ʻia ka maikaʻi o ka seam welded, ke hoʻonui nei ka ʻano a me nā kikoʻī o ka paipu kila welded, a me ke kila seamless. Ua hoʻololi ʻia ka paipu ma nā kahua he nui.Hoʻokaʻawale ʻia nā paipu kila welded i ka paipu wili wili pololei a me ka paipu wiliwili spiral e like me ke ʻano o ka weld.

ekahi.Hoʻokaʻawale ʻia o nā paipu welded welded tubes

Hoʻokaʻawale ʻia nā paipu welded e like me kā lākou hoʻohana ʻana: ua hoʻokaʻawale ʻia lākou i nā paipu welded maʻamau, galvanizing welded paipu, oxygen puhi welded paipu, uea lima, metric welded paipu, idler paipu, hohonu punawai paipu paipu, kaʻa paipu, transformer paipu, welded thin. - nā paipu pā, nā paipu ʻano ʻino a me nā paipu wiliwili ʻia.

elua.Ka Lahui o ka Paipu Welded

Hoʻohana nui ʻia nā huahana paipu Welded i loko o ka paila, kaʻa, ka hale moku, ke kūkulu ʻana i nā puka māmā a me nā puka makani kila, nā lako, nā ʻano mīkini mahiʻai, scaffolding, uea threading paipu, kiʻekiʻe kiʻekiʻe shelves, nā ipu a pēlā aku. hiki ke hoʻokō i nā koi o ka mea kūʻai aku, hiki ke hana ʻia ka paipu welded kūikawā kūikawā e like me nā koi o ka mea hoʻohana.

ekolu.KE KANAWAI HELU ANA O KA PIPE WELDED  

Aia nā ʻōkuhi no ka helu ʻana i ke kaumaha o ka paipu welded.

Kaumaha manaʻo no ka mika o ka paipu kila (ʻo 7.85 kg/dm3 ka nui o ke kila)

Kumu: W = 0.02466 (DS)S

Ma ka helu helu, ke kaumaha theoretical o W-steel paipu no ka mika, kg/m;

D – Ke anawaena o waho o ka paipu kila, mm;

S - ka mānoanoa o ka paia o ka paipu kila, mm.

ʻEhā.Wehewehe Kūlana a me ka hoʻohana ʻana i ka ʻoihana o ka paipu welded

ʻO nā mea maka i hoʻohana ʻia ma ka wili paipu welded he pā kila a i ʻole ke kaula kila.Hiki ke hoʻokaʻawale ʻia i loko o ka umu ahi welded paipu, uila welded paipu a me ka ʻakomi arc welded paipu ma muli o nā ʻenehana kuʻi ʻokoʻa.E like me nā ʻano kuʻikuʻi like ʻole, hiki ke hoʻokaʻawale ʻia i loko o ka paipu wili wili pololei a me ka pipe spiral welded pipe.per ke ʻano hopena, hiki ke hoʻokaʻawale ʻia i loko o ka paipu welded poepoe a me ka paipu welded kūikawā (square pipe flat pipe etc.) .Hiki ke hoʻokaʻawale ʻia nā paipu welded i loko o nā ʻāpana e like me kā lākou mau mea like ʻole a me ka hoʻohana ʻana:

1. GB/T3091-1993 (Galvanized Welded Steel Paipu no ka Haʻahaʻa Pressure Fluid Conveyance)

Hoʻohana nui ʻia no ka lawe ʻana i ka wai, gas, ea, aila, hoʻomehana i ka wai wela a i ʻole ka mahu a me nā wai haʻahaʻa haʻahaʻa haʻahaʻa a me nā paipu kumu ʻē aʻe.ʻO kāna mea hōʻikeʻike he kila Q235A.

2. GB/T3092-1993 (Galvanized Welded Steel Paipu no ka Haʻahaʻa Pressure Fluid Conveyance)
