O le a le mea e fa'atatau i le P235GH? O a mea e fetaui i Saina?

P235GH o se faʻatinoga maualuga o le vevela Fihekin ma paipa uʻamea uʻamea, o se uʻamea faʻatulagaina maualuga a Siamani. P235GH, EN10216-2 omiga seamless paipa uʻamea e fetaui ma le tulaga o le atunuu 20G, 20MnG (GB 5310-2008 maualuga-omiga boiler seamless uamea paipa).

P235GH u'amea uamea paipa seamless paipa e masani ona fa'afefeteina i le ogaumu arc eletise ma le okesene liliu pito i luga. Mo manaʻoga maualuga, e faʻaaogaina le faʻamamaina i fafo atu o le ogaumu, faʻafefe o le ogaumu faʻapipiʻi poʻo le faʻafefe faʻalua faʻafefete, electroslag remelting poʻo togafitiga gaogao, ma togafitiga vevela.

P235GH, EN10216-2 omiga paipa uʻamea seamless e talafeagai mo le gaosiga o vaʻa mamafa ma vaega meafaigaluega. Pe a faatusatusa i le uamea masani, P235GH uʻamea uʻamea e maualuga atu le malosi ma le faigata, faʻapipiʻi malulu ma le faʻaogaina o le uʻamea, vailaʻau vailaʻau, biocompatibility, meatotino faʻaletino ma le faʻatinoga o gaioiga.

Fa'ainisinia o le P235GH paipa u'amea u'amea: malosi tensile σb350~480 MPa; malosi e maua ai σs≥215 MPa; elongation δ5≥ 25%; malosi fa'afefete a'afiaga Akv≥47 J; Malosi Brinell ≤105~140 HB100

Su'ega vaila'au (vaega vaega, %) o paipa u'amea u'amea P235GH: ≤0.16 Si; 0.60~1.20 Mn; ≤0.025 Cr; ≤0.30 Ni; ≤0.30 Ku; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; P; ≤0.010 S; ≤0.30, ≤0.020 Al; C; ≤0.35, ≤0.03 Ti.
