DIN2391 pololei i unuhi ʻia i ke anu me ka hao ʻole pahu pahu pahu
ʻO ka paipu kila pololei he ʻano mea kiʻekiʻe kiʻekiʻe i hana ʻia e ke kaha kiʻi anu a i ʻole ka ʻōwili anu.No ka mea ʻo ka paia o loko a me waho o ka paipu kila pololei ʻaʻohe papa o ka oxide, ʻaʻohe leakage ma lalo o ke kaomi kiʻekiʻe, kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, ʻaʻohe deformation i ke anu anuanu, flaring, flattening a ʻaʻohe māwae, hoʻohana nui ia e hana i nā ʻāpana pneumatic a hydraulic. , e like me ka cylinder a i ʻole ka ʻaila ʻaila, hiki ke hoʻopaʻa ʻia i ka paipu ʻole, akā ʻo ka paipu welded pū kekahi (ma hope o ka mālama ʻana i ke anuanu).
Nā hiʻohiʻona o ka paipu kila pololei i unuhi ʻia (Rolled).
1. ʻOi aku ka liʻiliʻi o waho.
2. Hiki i ka precision kiʻekiʻe ke hana i ka hana liʻiliʻi
3. Kiʻi anu (rolling) i hoʻopau ʻia nā huahana me ka pololei kiʻekiʻe a me ka maikaʻi o ka ʻili.
4. ʻOi aku ka paʻakikī o ke keʻa o ka paipu kila.
5. ʻOi aku ka maikaʻi o ka hana o ka paipu kila, a ʻoi aku ka paʻakikī o ka metala.

Kiʻekiʻe kiʻekiʻe anu kiʻi pololei pololei paipuHe ʻano hou o ka paipu kila, ʻo kona ʻano nui ka pololei kiʻekiʻe.ʻElua mau ʻano hana hana o ʻelua wili kiʻekiʻe a me ʻekolu wili kiʻekiʻe.ʻOi aku ka kiʻekiʻe o ka pololei o ʻekolu mau wili kiʻekiʻe e hana i nā paipu kila liʻiliʻi i ʻōwili ʻia, hiki ke hoʻomalu ʻia i loko o kekahi mau kaula, akā ʻoi aku ka kiʻekiʻe o ke kumukūʻai.
Hoʻohana o ke kiʻekiʻe kiʻekiʻe kikoʻī kikoʻī kikoʻī kikoʻī anuu hao paipue mālama i ke kila, e hoʻomaikaʻi i ka hana ʻana a mālama i ka ikehu High precision anu i huki ʻia i ka seamless steel tube e pili ana i ka pololei o ka nui o loko a me waho (tolerances) pono, ma loko a ma waho o ka ʻili o ka roughness, roundness, pololei degere maikaʻi, hiki ke mālama nui i ka mīkini. manawa, hoʻomaikaʻi i ka hoʻohana waiwai, i ka manawa like e hoʻomaikaʻi i ka maikaʻi o ka huahana.
