ʻO nā paipu kila liʻiliʻi i hoʻopili pololei ʻia no nā mea kani

Hoʻopili ʻia ka paipu kila maʻemaʻe e ka paipu kila pōʻai holoʻokoʻa, ʻaʻohe weld ma ka ʻili o ka paipu kila, i kapa ʻia ka paipu kila ʻole.E like me ka hana hana, seamless kila paipu hiki ke maheleia i ka wela olokaa seamless kila paipu, anu olokaa seamless kila paipu, anu i hukiia seamless kila paipu, extruded seamless kila paipu, paipu jacking, etc. E like me ke kinona o ka pauku, seamless hiki ke maheleia ka paipu kila i elua ano: paipu poepoe a me ka paipu anoano.He huinaha, oval, huinakolu, hexagonal, ano anoano melon, hoku a me na eheu he nui.ʻO 900mm ka palena kiʻekiʻe, a ʻo ka palena iki he 4mm.E like me nā hoʻohana like ʻole, aia nā pā mānoanoa seamless kila paipu a me ka lahilahi paia seamless kila paipu.Hoʻohana nui ʻia ka paipu kila maʻemaʻe no ka paipu hoʻoheheʻe ʻana i ka petroleum geology, ka ʻūhā ʻana o ka paipu no ka ʻoihana petrochemical, ka paila paila, ka lawe ʻana i ka paipu a me ke kiʻekiʻe precision structural steel pipe no ke kaʻa, tractor a me ka mokulele.

ʻO ka hui kemika o nā paipu kila pololei e pili ana i ke kalapona C, silicon Si, manganese Mn, Sulfur S, Phosphorus P, Chromium Cr, ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻoi aku ka maʻalahi o ke kaumaha o ka paipu kila maʻemaʻe ke like ka ikaika o ka piko a me ka torsional. .He kila ʻāpana waiwai a hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana hana a me nā mīkini ʻāpana.
