Ko te Ngongo Rere Ārai he mea whakamahi nui ki roto i te paipa rere e hono ana ki te kei o ngā mīhini keri i te wā e mahi ana te keri. I raro i ngā āhuatanga noa, ka taea te hono i ngā Ngongo Rere Ārai hei hanga i tētahi paipa rere motuhake he kaha kawe pai. Kua whakamahia whānuitia ngā Ngongo Rere Ārai CDSR ki ngā wāhi mahi keri i UAE, Qinzhou-Haina, Lianyungang-Haina me ētahi atu wāhi o te ao.

Ngongo Momi me te Tukunga Ārai

Hanganga me ngā Rauemi

An Ngā Ngongo Momi me te Tukunga Āraihe mea hanga mai i te arai, ngā mowhiti maitai ātete-kakahu, ngā papa whakakaha, te uhi o waho me ngā hononga ngongo (ngā flange hanawiti rānei) i ngā pito e rua. Ko te nuinga o te wā ko te rauemi o te mowhiti maitai ātete-kakahu he maitai koranu.

Ngā Momo Ngongo

E rua ngā momo taunga e wātea ana mō te Ngongo Momi me te Tukunga Ārai, te Momo Nipple Rino, me te Momo Flange Hanawiti.

Momo Pūwero Rino

Momo Flange Hanawiti

Ki te whakatauritea ki te Momo Nipple Rino, he pai ake te mahi piko o te Momo Sandwich Flange, ā, he pai ake mō ngā tono he iti te wāhi tāutanga.

Ngā Āhuatanga

(1) He tino ātete ki te kakahu me te ātete ki te pānga.
(2) He pai te ngāwari me te mahi piko.
(3) He pakari āhua.
(4) He whānui te whakatauranga pēhanga, ā, ka taea te tu atu i te pēhanga pai me te pēhanga kino.

Ngā Tawhā Hangarau

(1) Rahi Pūwero Ingoa	500mm, 600mm, 700mm, 750mm, 800mm, 850mm, 900mm, 1000mm, 1100mm, 1200mm
(2) Te roa o te ngongo	1 m ~ 11.8 m (ātete: ±2%)
(3) Te Pēhanga Mahi	2.5 MPa ~ 4.0 MPa
(4) Te korehau e taea te whakamanawanui	-0.08 MPa
(5) Te pakeke o ngā mowhiti ātete-mau	HB 350 ~ HB 500
