ʻO ka paipu welded, ʻike ʻia hoʻi ʻo ka paipu kila welded, ua hana maoli ʻia me ka pā kila a i ʻole ke kaula i hoʻopaʻa 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 hana kiʻekiʻe, ʻoi aku nā ʻano like ʻole a me nā kikoʻī, a ʻoi aku ka liʻiliʻi o nā lako lako, 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 pani 'ia ka paipu ma na 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.

一.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 pipes, oxygen blowing welded pipes, uea lima, metric welded pipes, idler pipes, deep well pump pipes, automobile pipes, transformer pipe, welded thin - nā paipu pā, nā paipu ʻano ʻino a me nā paipu wiliwili ʻia.

二.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 like ʻole, 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.

三.KE KANAWAI HELU ANA O KA PAPA 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.

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

ʻO nā mea maka i hoʻohana ʻia ma ka wili pahu 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 kuʻi ʻokoʻa, 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 kēia mau 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 ke kila Q235A kāna mea hōʻike.

2. GB/T3092-1993 (Galvanized Welded Steel Pipe 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 i hōʻike ʻia he kila kila Q235A.

3. GB/T 14291-1992 (Pipe Welded no ka Mine Fluid Transport)

Hoʻohana nui ʻia no kaʻu ea kaomi, hoʻoheheʻe ʻana, kumu hoʻokahe kinoea me ka paipu kila wili pololei.ʻO ke kila kila Q235A a me B ka mea hōʻike.GB / T 14980-1994 (Large Diameter Welded Steel Pipe for Low Pressure Fluid Conveyance).Hoʻohana nui ʻia no ka lawe ʻana i nā wai haʻahaʻa haʻahaʻa e like me ka wai, ka wai, ke kinoea, ka ea, ka mahu wela a me nā kumu ʻē aʻe.ʻO ke kila Q235A kāna mea hōʻike.

4. GB/T12770-1991 (Welded stainless steel paipu no ka mechanical structure)

Hoʻohana nui ʻia no nā mīkini, nā kaʻa, nā kaʻa, nā lako, nā hōkele a me nā hōkele a me nā ʻāpana mechanical a me nā ʻāpana hana.ʻO kāna mau mea kikoʻī he 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, etc.

GB/T12771-1991 (Welded Stainless Steel Pipe for Fluid Transport)

Hoʻohana nui ʻia no ka lawe ʻana i ka media corrosive haʻahaʻa haʻahaʻa.

ʻO nā mea ʻelele he 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, etc.
