Amapayipi Epulasitiki Aqiniswe Nge-Fiberglass: Izimpawu Zezobuchwepheshe kanye Namathemba Emakethe

Amapayipi Epulasitiki Aqiniswe Nge-Fiberglass: Ipayipi Elisha Elihlanganisiwe Elisebenza Kakhulu kanye Nezicelo Ezibanzi

Amapayipi epulasitiki aqiniswe nge-Fiberglass(amapayipi e-FRP) angamapayipi ayinhlanganisela enziwe ngokuqiniswa kwe-fiber yengilazi kanye ne-resin njenge-matrix, enikeza kokubili izakhiwo ezingasindi neziqinile. Imelana nokugqwala futhi kulula ukuyifaka, isiphenduke enye indlela esebenzayo yamapayipi ensimbi endabuko kumaphrojekthi wokwakha kanye nezinhlelo zokudlulisa amandla. Ngezansi ukubuka konke okuhlanganisa izici ezibonakalayo, amazinga okukhiqiza, nedatha yemakethe.

Incazelo Nokubunjwa Kwezinto

Uhlelo olubalulekile lwamapayipi e-FRP luthobela izindinganiso zikazwelonke eziqinile:

Isendlalelo sokuqinisa sisebenzisa i-alkali-free noma i-alkali ephakathi nendawo engasontekile ye-fiber roving (GB/T 18369-2008), lapho ubuningi befayibha buthinta ngokuqondile ukuqina kwendandatho;

I-resin matrix iqukethe i-polyester resin engagcwalisiwe (GB/T 8237) noma i-epoxy resin (GB/T 13657). I-resin yezinga lokudla (GB 13115) iyimpoqo kumapayipi amanzi aphuzwayo;

Isendlalelo esigcwele isihlabathi siqukethe isihlabathi se-quartz (SiO₂ purity>95%) noma i-calcium carbonate (CaCO₃ purity>98%), enomswakama olawulwa ngokuqinile ngaphansi kuka-0.2% ukuze kuqinisekiswe ukunamathela kwe-interlayer okuqinile.

Ukwakha Ubuchwepheshe

Izinqubo ezijwayelekile zifaka ukujikajika kobude obugxilile, ukusakaza okumaphakathi, kanye nokujikajika okuqhubekayo. Inqubo yokusonta ivumela ukulungisa isilinganiso samandla phakathi kwezikhombisi-ndlela ze-axial neziyindilinga ngokuklama ama-engeli efayibha. Ubukhulu bongqimba olugcwele isihlabathi buthinta ngokuqondile isilinganiso sokuqina kwepayipi.

Izixazululo Zokuxhuma

Beka kuqala izigxivizo ze-O-ring ze-socket-type (ezikwazi ukuhlalisa ± 10mm ukuguqulwa kokushisa). Ngokusetshenziswa kwamakhemikhali, ukuxhumeka kwe-flange (izilinganiso zokucindezela kwe-PN10/PN16) kuyanconywa. Ukufakwa kufanele kuhambisane ngokuqinile nezicaciso zokusebenza kwezindawo ezi-dual-hoist.

Izimo Zokusebenza Ezijwayelekile

Amapayipi Okwakha: Amapayipi anobubanzi obukhulu (DN800+) angashintsha amapayipi kakhonkolo. Nge-coefficient yangaphakathi yokugwedla engu-0.0084 nje, umthamo wokugeleza udlula amapayipi e-HDPE ngo-30%.

Imibhobho Yamandla: Ukufakwa okuqondile kokungcwaba okunokuqina kwendandatho ≥8 kN/m² kususa isidingo sokuvaleka kukakhonkolo.

I-Chemical Conveyance: Ukumelana ne-Acid ne-alkali kuhlangabezana nezindinganiso ze-ASTM D543, nempilo yokuklama engaphezu kweminyaka engama-50.

Ukunisela Ngenkasa Kwezolimo: Ukukala kuphela ingxenye yesine yamapayipi ensimbi, izindleko zokuthutha nokufaka zingancishiswa ngaphezu kwama-40%.

Usayizi Wemakethe

Umhlaba jikeleleIpayipi le-FRPImakethe kulindeleke ukuthi ifinyelele ku-RMB 38.7 billion (cishe ama-USD 5 billion) ngo-2025, ikhula ibe ngu-RMB 58 billion ngo-2032 (CAGR: 5.97%). Ngaphakathi kwezigaba, amapayipi e-epoxy resin ezinhlelweni zobunjiniyela basolwandle abonisa izinga lokukhula elingu-7.2%.
