Kia pehea te taumaha o te paipa rino ngawari

I roto i te hangarau tuku wai me te rerenga wai, ngā whatunga paipa ā-tāone, me ngā pūnaha paipa ahumahi,paipa rino ngāwarikua waiho hei whakakapinga pai mō ngā paipa rino maka me te maitai tuku iho nā te mea he pai rawa ngā āhuatanga miihini me te ātete ki te waikura. He mea nui te mārama ki ngā tawhā hangarau matua o ngā paipa rino ngāwari mō ngā kaihoahoa, ngā kaihoko, me ngā kamupene hanga, ahakoa mō ngā puna wai, mō te kawe waipara rānei. Ka tangohia e tēnei tuhingaPaipa rino ngāwari a DINSENhei tauira hei whakamārama pūnaha i ōna whakatakotoranga, tōna taumaha, tōna pēhanga mahi, me ōna āhuatanga paninga.

I. Ngā Whakatakotoranga me ngā Ahu o te Paipa Rino Māeneene: Me pēhea te Whakatau i te Tauira?

I te wā e whiriwhiri ana i ngā paipa, me whakamārama tuatahi te rahi me ngā ine o ngā paipa rino ngāwari. Ko ngā paerewa o te ao e ahu mai ana i te ISO 2531, i te EN 545 rānei, e whakarōpūtia ana e te diameter ingoa (DN).

Hei tauira, he paipa rino ngāwari a DINSEN, e whakamahia whānuitia ana ngā paipa K9 (taumata matotoru pakitara paerewa), me ngā diameter ingoa mai i te DN80 ki te DN2000. Anei ētahi rahi paipa noa:

• DN80: Te whānui o waho 98mm, te matotoru o te pakitara 6.0mm
• DN100: Te whānui o waho 118mm, te matotoru o te pakitara 6.0mm
• DN200: Te whānui o waho 222mm, te matotoru o te pakitara 6.3mm
• DN400: Te whānui o waho 429mm, te matotoru o te pakitara 8.1mm
• DN1000: Te whānui o waho 1048mm, te matotoru o te pakitara 13.5mm

Ka pāngia te kaha pēhanga me te taumaha o te paipa e ngā matotoru pakitara rerekē (K8, K9, K10, K12).Ka taea e ngā kaiwhakamahi te whiriwhiri i te mea e tika ana kia rite ki te hiahia hoahoa.

II. Taumaha mō ia mita o te paipa rino ngāwari: E hia te taumaha o te paipa rino ngāwari?

Ko tētahi pātai e pā ana ki te hokohoko hangarau ko: E hia te taumaha o te paipa rino ngāwari? Ko te taumaha o te paipa rino ngāwari ko te taumaha o te tinana o te paipa me te taumaha o te putanga, e pā tika ana ki ngā utu kawe, te hiki, me te tāutanga.

Hei tauira, mā te whakamahi i te paipa rino kōpiko o te DINSEN K9 (te roa paerewa 6 mita), ko te taumaha ariā e whai ake nei:

• DN100: Tata ki te 15.1 kg/m → 95 kg mō ia paipa
• DN200: Tata ki te 30.6 kg/m → 194 kg mō ia paipa
• DN300: Tata ki te 50.8 kg/m → 323 kg mō ia paipa
• DN500: Tata ki te 104.3 kg/m → 669 kg mō ia paipa
• DN800: Tata ki te 215.2 kg/m → 1394 kg mō ia paipa

Tērā pea ka rerekē te taumaha tuturu nā runga i ngā āhuatanga pēnei i te matotoru o te paninga konutea me te arai moata sima o roto. Ka taea e DINSEN te whakarato i ngā pepa tatau taumaha tika mō te tahua kaupapa me te whakamahere whakahaere.

III. Te Pēhanga Mahi o te Paipa Rino Muku

He kaha te kume me te kaha pēhanga porowhita o ngā paipa rino ngāwari. Ko te pēhanga mahi o ngā paipa rino ngāwari paerewa o te taumata K9 he 16 pae (1.6 MPa), ko ngā matotoru pakitara teitei ake (pērā i te K12) he pai mō ngā tono pēhanga o te 25 pae, tae atu ki te 40 pae.

Ka hangaia ngā paipa rino ngāwari a DINSEN kia rite tonu ki ngā paerewa ISO 2531. Ka whakamatautauria ia paipa ki te wai ātete i mua i te wehenga atu i te wheketere hei whakarite kia 1.5 ngā wā teitei ake te tauwehenga haumaru i te pēhanga mahi hoahoa, kia tino pai ai mō te tuku wai tawhiti, ngā paipa whakaara teihana papu, me ngā paipa ahumahi pēhanga teitei.

IV. Paninga Konutea hei Tiaki i te Waikura

Te Tūranga o te Paninga Konutea ki ngā Paipa Rino Māeneene Ko tētahi o ngā mahi tiaki tino nui mō ngā paipa tanumia ko te paninga konutea ki ngā paipa rino māeneene. Ehara i te mea ka whakaratohia e te paninga konutea he tiaki katote anake, engari ka hangaia hoki he pūnaha ārai-waikura hiato me te peita o waho, te hipoki polyethylene rānei.

Ko ngā paipa rino ngāwari a DINSEN he mea paerewa me te paninga konutea ≥200 g/m² (e ai ki te paerewa ISO 8179), kua hipokina ki te uku epoxy whero, ki te paparanga whakaoti polyurethane rānei, e whakapai ake ana i te ātete ki te waikura me te roa o te ora. Mō ngā oneone waikura, mō ngā wāhi ātete nui rānei, kei te wātea he paninga konutea tāpiri + kiriata PE, paninga polyurethane katoa rānei, me te roa o te ora ratonga kua hoahoatia mō te 50-100 tau.

V. He aha i whiriwhiri ai i ngā paipa rino ngāwari a DINSEN?

Hei kaiwhakarato paipa rino ngāwari ngaio, ka tukuna e DINSEN te whānuitanga o ngā whakaritenga mai i te DN80 ki te DN2000, e tautoko ana i ngā matotoru pakitara rerekē pēnei i te K8, K9, K10, me te K12, ā, ka taea te whakarite i ngā roa, ngā arai o roto (moata sima/kapia epoxy), me ngā otinga tiaki waikura o waho kia tutuki ai ngā hiahia o te kiritaki.

Kua whakamanahia ngā paipa rino katoa e te ISO 2531 / EN 545. Kei te wātea ngā ripanga taumaha katoa, ngā ine, te pēhanga mahi, me ngā tawhā paninga konutea. E tautokona ana ngā ratonga takai kaweake o te ao me ngā ratonga kawe waka kotahi-mutunga.
