ʻoluʻolupaipu kilaʻO ka hoʻolālā he ʻehā ʻāpana o ka paipu kila maʻalahi, ʻo ka ʻaoʻao o loko e extruded thermoplastic tube, ka wai hoʻoili mai ke sila;ma waena o ʻelua papa o ka uhi ʻana o ka paipu polyethylene i hoʻopiha ʻia i ke kalapona, me ke kūʻē ʻana i ka hoʻoheheʻe ultraviolet o ka hiki no ka manawa pōkole, a e hoʻokuʻu i waho.ʻO ka ʻaoʻao o waho he pale mānoanoa o waho, no ka mālama ʻana i ka lalo o ka paipu mai nā hopena o waho.

Hoʻopili ka kikoʻī o ka paipu kila maʻalahi i ka helu ANSI, e like me ka papa 300 like 5.15MPa;papa 400 like .89MPa;10.3MPa flexible steel grade 600 equivalent design base is API17J17K and RP17B land Flexible pipe design specifications little within a deviation from the API specifications, hoohana API17J classification method and materials, pressure, tension and damage limits are prescribed range.

Hoʻolālā ʻia ka hoʻāʻo e like me ka APIRP17B terminal kūpono e hoʻokō i nā koi e mālama i ka kūpaʻa o ke kūkulu ʻana, e hōʻoia i ka hoʻopaʻa ʻana o ka papa extruded i loko a me waho, a hiki ke hōʻoia i ka lawe ʻia ʻana o ka ukana tensile a compressive i ka hale paipu.Ma hope o ka hoʻoheheʻe ʻana i nā mea hoʻopili terminal a me ka hoʻāʻo tensile axial.
