I roto i ngā mahi ahumahi, inā koa i roto i te rāngai hinu me te hau, he mea nui te kounga o ngā paipa rino. Ko tētahi o ngā huarahi tino whai hua hei whakarite i te roa me te pakari o ēnei paipa ko te whakamahi i ngā paninga epoxy honohono honohono (FBE). He mea nui te mārama ki ngā paerewa paninga FBE mō te hunga katoa e whai wāhi ana ki te hoko, te tāuta, te tiaki rānei i ngā paipa wai rino me ngā taputapu.
Ko te nuinga o ngā paninga FBE e whakamahia ana mō ngā momo paipa rino, tae atu ki ngā paipa SSAW (Spiral Submerged Arc Welded), ngā paipa ERW (Electric Resistance Welded), ngā paipa LSAW (Longitudinal Submerged Arc Welded), ngā paipa kore hononga, me ngā momo hononga pēnei i ngā tuke, ngā tī, me ngā whakaiti. Ko te kaupapa matua o ēnei paninga he tiaki i te waikura, he mea nui hei pupuri i te hanganga paipa mō te wā roa.
He aha te meaPaninga FBE?
Ko te paninga FBE he paura epoxy whakamahana e pania ana ki te mata o te paipa maitai. Ko te tukanga tono ko te whakamahana i te paipa ki tētahi pāmahana motuhake, kātahi ka pania te paura epoxy, ka rewa, ka hanga he hononga kaha ki te mata o te paipa maitai. Mā tēnei tukanga ka hangaia he paninga maeneene, pakari, ā, he ātete ki ngā matū ka taea te tu atu ki ngā āhuatanga taiao kino.
Te hiranga o ngā paerewa paninga FBE
He mea nui te tutuki i ngā paerewa paninga FBE mō ngā take e whai ake nei:
1. Ātete ki te waikura: Ko te mahi matua o te paninga FBE he tiaki i te maitai mai i te waikura. Mā ngā paerewa e tika ana ka tika te paninga, ā, ka tutuki i ngā whakaritenga matotoru me te piri e tika ana hei whakarato i te tiakitanga tino pai.
2. Te Whakapūmau Kounga: Mā te whai i ngā paerewa kua whakatūria, ka taea e ngā kaihanga te whakamana i te kounga o ā rātou hua. He mea nui rawa tēnei mō ngā kamupene e whakaputa ana i ngā rahinga nui o ngā paipa maitai, hei tauira, he kamupene me ngā rawa katoa o te 680 miriona yuan, he putanga ā-tau o te 400,000 tana o ngā paipa maitai porowhita, me te uara putanga o te 1.8 piriona yuan.
3. Te Whakatutukitanga: He maha ngā ahumahi e pāngia ana e ngā ture tino pakari mō ngā rauemi me ngā tukanga e whakahaerehia ana e rātou. Mā te whakatutukitanga i ngā paerewa paninga FBE ka āwhina i ngā kamupene ki te karo i ngā take ture me te pupuri i tō rātou ingoa rongonui i te mākete.
4. He roa te mau, he pono hoki: Mā te paninga tika o te paninga FBE ka roa ake te ora o ngā paipa rino. He mea nui tēnei pono mō ngā ahumahi e whakawhirinaki ana ki ēnei paipa hei kawe i te wai, te hinu me te hau.
Ina whakaarohia ana ngā paninga FBE, he mea nui kia mārama ki ngā paearu matua mō tā rātou tono:
- ASTM D638: E whakamārama ana tēnei paerewa i ngā āhuatanga kume o ngā kirihou (tae atu ki ngā paninga FBE) kia taea ai e rātou te tu atu i ngā taumahatanga e pā ana ki te whakamahinga.
- ASTM D3359: Ka whakamātautau tēnei paerewa i te piri o te paninga ki te papa, he mea nui kia mau tonu ai te paninga FBE i roto i te wā.
- AWWA C213: E aro ana tēnei paerewa ki ngā whakaritenga mō ngā paninga epoxy honohono-hanumi mō ngā paipa wai rino, e whakarato ana i ngā aratohu mō te tono, te tirotiro, me te whakamātautau.
hei whakamutunga
Hei whakarāpopototanga, he mea nui te mārama ki ngā paerewa paninga FBE mō te hunga katoa e uru ana ki te umanga paipa maitai. Mā te arotahi ki te tiaki i te waikura, te whakapūmau kounga, me te tutuki i ngā ture, he mea nui ēnei paerewa ki te whakarite i te roa o te mahi me te pono o ngā paipa me ngā taputapu maitai. Ko ngā kamupene e whakapau kaha ana ki te piri ki ēnei paerewa, pērā i te hunga he kaha ā rātou pūkenga whakaputa me ngā rawa, kāore e taea te whakapai ake i te kounga hua engari ka whakapakari anō hoki i tō rātou tūranga i roto i te mākete whakataetae. I te mea kei te piki haere tonu te hiahia mō ngā paipa maitai pakari me te pono, ka piki haere tonu te hiranga o ngā paninga FBE me ngā paerewa mō tā rātou tono.
