ʻO ASTM A213 GR.T22 SA333 GR.6 ʻO ka pahu hao hao ʻole no ka lawe ʻana i ka wai.

He nui ka hoʻohana ʻana o ka paipu kila seamless.

ʻO 1, ʻōwili ʻia ka paipu kila maʻamau maʻamau e ke kila kila kila, ke kila kila haʻahaʻa a i ʻole ke kila kila kila, ka hopena kiʻekiʻe, i hoʻohana nui ʻia no ka lawe ʻana i ka pipeline wai a i ʻole nā ​​ʻāpana hana.

2, e like me ka hoʻohana ʻana i nā lako like ʻole i ʻekolu mau ʻāpana:

A. Hāʻawi ʻia e like me ka haku mele ʻana a me nā waiwai mechanical;

b. Hoʻolako e like me nā waiwai mechanical;

c. Hoʻolako e like me ka ho'āʻo hydraulic. ʻO nā paipu kila i hoʻolako ʻia e like me ka papa a me ka papa b, inā hoʻohana ʻia e kū i ke kaomi wai, e hoʻokau pū ʻia i nā hoʻokolohua hydrostatic.

3, ʻo ke kumu kūikawā o ka paipu maʻemaʻe ʻole me ka paila seamless pipe, ka mana kemika, geological seamless steel pipe a me ka petroleum seamless pipe a pēlā aku.

Seamless kila paipu i hollow pauku, nui hoʻohana 'ia no ka lawe ana i ka wai pipeline, e like me ka lawe ana i ka aila, maoli kinoea, kinoea, wai a me kekahi mau mea paa, etc.

Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila hinu, ka pahu hoʻoili kaʻa, ka pahu kaʻa a me ka scaffolding kila i hoʻohana ʻia i ke kūkulu ʻana. Hiki iā ia ke hoʻomaikaʻi i ka nui o ka hoʻohana ʻana i nā mea, hoʻomaʻamaʻa i ke kaʻina hana, mālama i nā mea a me nā hola hana, a ua hoʻohana nui ʻia i ka hana ʻana i ka paipu kila.
