DIN / EN hydraulic faʻapipiʻi uʻamea uʻamea o loʻo gaosia e tusa ai ma tulaga DIN2391-C poʻo EN10305-4, ma o tulaga tuʻuina atu e masani lava BK, NBK, GBK, ma isi. paipa ta'avale ta'avale, faiga fa'alelei, ma faiga pneumatic.O le hydraulic e masani ona vaevaeina i vaega nei e tolu:
1. DIN/EN maualuga sa'o lelei paipa u'amea seamless
O mea mataʻina e faia i mea e sili ona lelei carbon sila mai le Baosteel poʻo Tiangang, lea na faʻafefeteina le fufuluina o le acid, faʻamaonia saʻo, le faʻamaʻiina o le vevela vevela (NBK state), faʻataʻitaʻiga e le faʻaleagaina, faʻafefe maualuga ma fufulu vai o totonu. pu o le paipa u'amea, togafitiga puipuia ele o puipui totonu ma fafo o le paipa u'amea ma suauʻu ele faʻamaonia, ma le puipuiga o le pefu togafitiga ma pito uma e lua o le ufiufi.O paipa uamea gaosia e maualuga le saʻo ma lelei lelei.E leai se oxide layer i totonu ma fafo puipui o paipa uamea.
O paipa uʻamea e mafai ona tatalia le maualuga o le tafe o le suavai, ma o paipa uʻamea e le faʻaleagaina i le taimi o le malulu.E mafai ona faʻalauteleina, faʻamafola, ma leai ni taʻe.O mea fa'ainisinia e mafai ona punou e aunoa ma se fa'aletonu i so'o se itu.E masani ona faʻaaogaina mo le saunia o paipa uʻamea i le suauʻu eletise eletise, e lauiloa foi o le paipa faigata i le hydraulic system, o paipa uʻamea saʻo mo taavale e mafai ona faʻamalieina manaʻoga o tagata faʻatau i le maualuga maualuga, maualuga le lamolemole, malosi malosi, ma mea faʻainisinia mo paipa uʻamea.
2.DIN/EN maualuga sa'o sa'o paipa u'amea
O le maualuga o le saʻo lelei paipa uʻamea lamolemole e faʻaaogaina mo le electrogalvanizing, ma o totonu ma fafo puipui o paipa uʻamea o loʻo ufiufi i samasama samasama (lanu zinc), sinasina paʻepaʻe, togafitiga passivation, ma le umi o paipa uamea e mafai ona i totonu ole 6 mita. .E masani ona faʻaaogaina i alamanuia e pei o paipa uʻamea taʻavale, paipa paipa, vaʻalele, faʻatoʻaga ma vaomatua masini, inisinia masini, nofoaafi taavale, vaa, ma isi.
3. DIN / EN maualuga saʻo uliuli phosphate paipa uamea
I luga o le faʻavae o le faʻaaogaina o le DIN2391 / EN10305 maualuga-saʻo lelei paipa uʻamea susulu, o le puipui totonu ma fafo o le paipa uʻamea saʻo lelei o loʻo faʻamaʻiina i se faʻamaʻi faʻafefeteina sui faʻamaʻi, fausia ai se ata tifaga puipui uliuli i totonu ma fafo puipui o le uamea. paipa e puipuia ai le ele.O paipa u'amea u'amea uliuli o lo'o i ai le iila lanu uliuli, lanu lelei ma le malosi o le ele.High sa'o uliuli phosphated uamea paipa e masani ona faaaoga mo paipa i faiga hydraulic, faapea foi mo ferrule (paipa uamea) sooga ma uelo sila paipa paipa.
