Whakaahuatanga: Ko te R407 he pearlitic wera-aukati maitai hiko me te paninga konutai iti-waiwai kei roto 2.5% Cr - 1% Mo. Whakamahia te DCEP (te hiko o naianei tika) ka taea te paihere ki nga waahi katoa.Ko te weldment me whakamahana ki te 200 ~ 300°C i mua i te whakapiri.

Taupānga: Whakamahia mō te fehokotaki'anga teitei-te pāmahana me te teitei-press pipelines ki te pāmahana mahi i raro i 550 ° C, mīhini matū waihanga, taputapu hangai hinu, etc.

Panui:

1. Me tunuhia te electrode mo te 1 haora i te 350 ℃ i mua i te mahi whakapiri;

2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.
