Sisitemu zitandukanye zisanzwe zitanga ibipimo bitandukanye byo gukoresha, kandi uburemere bwibipimo bya pipe ntabwo ari bimwe.
Uyu munsi tuzaganira kuri sisitemu isanzwe ya EN10220.
Incamake ya EN 10220 isanzwe
EN 10220ni igipimo cyiburayi kubipimo no kwihanganira imiyoboro idafite ibyuma kandi isudira.
Ikigereranyo cya EN 10220 gifite uburyo bwinshi bwo gukoresha kandi gikoreshwa cyane mu nganda za peteroli, gaze, imiti, ubwubatsi, n’inganda zitunganya amazi.
Igipimo gikubiyemo diameter yo hanze (OD) hamwe nuburebure bwurukuta (WT) rwimiyoboro yicyuma, itanga umurongo ugaragara wamabwiriza hamwe nibisobanuro bimwe byerekana igishushanyo mbonera no gukora kugirango habeho guhuza no guhinduranya ibicuruzwa biva mu nganda byakozwe nababikora batandukanye.
Uburyo bwo Kubara Ibiro
Uburyo bwo kubara misa kuri metero kuburebure bwatanzwe muri EN 10220.
M = (DT) × Tx0.0246615
Mni misa kuburebure bwa kg / m,
Dni Byerekanwe hanze ya diameter muri mm,
Tni uburebure bwurukuta muri mm.
Iki kintu gishingiye ku bucucike bwa 7,85 kg / dm3. (kg / dm3ni igice cyubucucike, kubimetero kubic.)
Indangagaciro zabazwe zishobora no gukoreshwa kuri tubes zifite agaciro kinshi, ariko rero zigomba kugwizwa nimpamvu ya
1.015 kubwibyuma bya austenitike ain Iki kintu gishingiye ku bucucike bwa 7.97 kg / dm3）.
0.985 kuri ferritic na martensitis ibyuma bitagira umwanda （Iki kintu gishingiye ku bucucike bwa 7,73 kg / dm3）.
Ibiharuro birashobora gukorwa hashingiwe kubiciro bitandukanye bitandukanijwe kuri buri tsinda ryibyuma bitagira umwanda byatanzwe muri EN 10088-1.
EN 10220 Urutonde
EN 10220ukurikije urwego rwo kugereranya imiyoboro nibikoresho byayo.Hano hari urukurikirane.
urukurikirane rwa 1: hanze ya diametre ibikoresho byose bikenerwa mukubaka sisitemu ya pipine byemewe;
urukurikirane rwa 2: diametero zo hanze zitari ibikoresho byose bisanzwe;
urukurikirane rwa 3: diametero zo hanze kubintu bike bisanzwe bisanzwe bihari.
Ibipimo byerekana uburemere bwa EN 10220 Urukurikirane 1
Umuyoboro OD w'uruhererekane ukurikiza amahame mpuzamahanga cyangwa inganda neza, kandi isoko ritanga ibikoresho byuzuye nka flanges, guhuza, hamwe n'inkokora.
Ibipimo byuzuye byoroshya igishushanyo mbonera nogushiraho kandi bigabanya ibikenerwa kubice bitari bisanzwe hamwe nigiciro cyo kwihitiramo.
Ibipimo byerekana uburemere bwa EN 10220 Urukurikirane 2
Igice cya OD cyubu bwoko bwo kuvoma kirasanzwe, ariko ntabwo ibikoresho byose byemewe.Ibikoresho bimwe bisanzwe, nka flanges cyangwa inkokora, birashobora kuboneka, mugihe ibindi bice bishobora gukenera guhindurwa, byiyongera kubiciro no kugorana kwumushinga.
Imiyoboro yuburemere bwa EN 10220 Urukurikirane 3
Ibi bikunze kugaragara hamwe nubunini bwihariye cyangwa budasanzwe buringaniye busaba umubare munini wibikoresho byabugenewe hamwe nibigize, kuzamura igiciro cyo gutegura no gushyira mubikorwa umushinga, ndetse no kongera amasoko nigihe cyumusaruro.
Ibipimo by'ibipimo byerekana uburemere bwurukuta 70 -100 mm
Ku miyoboro ikikijwe cyane ifite uburebure bwurukuta kuva kuri mm 70 kugeza kuri mm 100, ibisabwa bisobanurwa muri EN 10220, Imbonerahamwe 2.
Ibikoresho byo kurukuta ruremereye rufite ibipimo bikurikije imbonerahamwe ya 2 ntibishobora kuboneka hatitawe ku ruhererekane ruri mu mbonerahamwe ya 1 ahabwa diameter yo hanze.
Turi abanyabugeni bo mu rwego rwo hejuru basudira ibyuma bya karuboni kandi bitanga ibicuruzwa biva mu Bushinwa, kandi tunabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
