Spaipu kila welded piral

ʻIke ʻia ʻo Spiral welded steel pipe e like me ka spiral steel pipe a me spiral welded pipe, kahi i hoʻohana ʻia ai ke kila carbon structural haʻahaʻa a i ʻole nā ​​​​mea hao hao haʻahaʻa haʻahaʻa e like me ke kihi o ka laina spiral (i kapa ʻia ʻo ka angle forming) i ʻōwili ʻia i loko o kahi paipu, a laila ʻO ka paipu i hui pū ʻia i hana ʻia, hiki ke hana i kahi hana ʻokiʻoki o ka paipu kila nui.Hoʻohana nui ʻia ka coil no ka ʻaila a me nā pipeline gas, kāna mau kikoʻī OD * mānoanoa pā.ʻO ka wili ʻaoʻao a me ka ʻaoʻao ʻelua kuʻihao spiral welded paipu e hōʻoia i ka hoʻāʻo hydrostatic, ka ikaika tensile o ka weld a me ka hana anu e pono ai.

(1) ke kaomi wai hoʻoili spiral submerged arc welded paipu: hoʻohana nui ʻia no ka lawe ʻana i ka aila, pipeline kinoea maoli;

(2) ka hoʻouna ʻana i ka wai kaomi kiʻekiʻe alapine wili ʻia nā paipu kila me ka hili ʻana: wiliwili kiʻekiʻe kiʻekiʻe-frequency lap kuʻi ʻana no ke kaomi wai hoʻoili spiral kiʻekiʻe-frequency welded steel pipe.ʻO ka hiki o ka paipu kila ma lalo o ke kaomi, ka plasticity maikaʻi, ka maʻalahi o ka wili a me ke kaʻina hana;

(3) haʻahaʻa puʻe wai hoʻoili spiral submerged arc welded steel paipu: pālua ʻaoʻao ʻakomi submerged arc kuʻihao a hoʻokahi ʻaoʻao kuʻihao i loko o ka ʻōnaehana kānāwai no ka haʻahaʻa haʻahaʻa wai e like me ka wai, ke kinoea, ka ea a me ka mokumahu me ka puʻupuʻu arc welded paipu.

ʻAʻole ka laukilapaipu

ʻO nā hiʻohiʻona huahana paipu ʻole:
1. ho'āʻo hoʻokō kaʻina paipu maʻemaʻe: hoʻāʻo hoʻopololei, hoʻāʻo tensile, hoʻāʻo hopena, hoʻāʻo flaring, hoʻāʻo paʻakikī, hoʻāʻo metallographic, hoʻāʻo kūlou, hoʻāʻo nondestructive (me ka hoʻāʻo ʻana o ka eddy o kēia manawa X-ray a me ka ultrasonic).

2.Seamless paipu kemika kālailai: ka kemikala haku mele 'ana o ka mea no ka kemika kālailai, kemika hui e hoʻokō i ka maʻamau koi.

3.Seamless paipu kaomi a me ka hydrostatic ho'āʻo mea no ka puʻe puʻe e i loko o ka hydrostatic ho'āʻo, ka mea, aole e malama i ka prescribed kaomi waiwai ole emi ma lalo o 5 kekona, aole e hoike, ka mea maʻamau hāʻawi hydraulic kaomi ho'āʻo he 2.45MPa kaomi ʻO ka ho'āʻo kaomi. P = 0.5MPAa.

4.The corrosion ho'āʻo: 'oihana corrosion-kū'ē i ke kila paipu e like me ka maʻamau hoʻoponopono a aelike ma waena o ka corrosion o ka paipu kila corrosion kū'ē ho'āʻo,ʻaʻohe intergranular corrosion.

ʻO nā hiʻohiʻona o ka paipu seamless
(1) ʻoi aku ka liʻiliʻi o ke anawaena o waho.

(2) Hiki i ka precision kiʻekiʻe ke hana i nā mea liʻiliʻi o ka maka.

(3) ka paipu kila huki anu me ka pololei kiʻekiʻe a me ka maikaʻi o ka ʻili.

(4) ʻoi aku ka paʻakikī o kahi paipu kila.

(5) ʻoi aku ka maikaʻi o ka paipu kila, me ka metala paʻa.
