Pumi kiʻekiʻepuʻu welding flangeʻo ia kekahi o nā koi nui loaflangehuahana ma ka makeke. ʻO ka papa kaomi maʻamau o ke kaomi kiʻekiʻepuʻu welding flangeaia ma waena o 0.5MPA-50mpa. ʻO keʻano hoʻolālā o ke kaomi kiʻekiʻepuʻu welding flangeua māhele ʻia i ka flange unit, flange integral, a me ka flange insulation. E like me ke ʻano o ka flange surface, hiki ke hoʻokaʻawale ʻia i ka flange sealing surface: plane, concave, concave, tenon groove surface, ring connect surface.
Puku-weli flangeloaʻa i ka sila hilinaʻi, hana maikaʻi loa a me ke ʻano nani. Loaʻa iā Butt welding flange nā mea maikaʻi o ka pale ʻana i ka ʻaʻahu, ke kūpaʻa wela kiʻekiʻe, ka pale ʻana i ka corrosion, ke kūpaʻa abrasion a me ke ola lawelawe lōʻihi.

Ma muli o kāna hana ikaika hopena kū hoʻokahi, ua hoʻomaikaʻi maikaʻi ʻia ma luna o nā paipu pā paʻa ʻē aʻe, a ʻo kona ʻoʻoleʻa apo he 1.3 mau manawa o nā paipu pā paʻa. Ma lalo o ka mahana lawelawe i helu ʻia a me ke kaomi, hiki ke ola o ka paipu ma mua o 50 mau makahiki, me ka anti-ultraviolet a me ka anti-radiation, i ʻole e mae ka huahana.
