He kowiri tira

He maha nga momo hua o te kowiri tira: nga papa me nga piripiri paipa me nga putorino paipa me nga piripiri paitini

Ko te nuinga o te kowiri tira ka taea te wehe ki nga waahanga e wha:

Kotahi: Momo Taakapa iti, Kaore i te Molybelenum, Pren: Pene: 24-25, ka taea te whakakapi i te AISI 304, 316 ranei mo te aukati i te aukati.

Tokotoru: Ko te momo o te remou, te nuinga kei roto i te 25% CR, kei runga ano hoki i te molybdenum me te hauota, he nui ake te peehi, he nui ake te pareparenga.

E wha: Ko te Molybdenum te Molybdenum me te Nitrogen, he maha tonu nga tohu paerewa me te parahi me nga taonga totika me nga taonga miihini, he rite ki te super Austenitic kowiri tira. (Tuhipoka: Pren: Te uara o te ātete o te ātete)

Chemical composition The main alloying elements of duplex steel are Cr, Ni, Mo and N. Among them, Cr and Mo are used to increase the ferrite content, while Ni and N are austenite stabilizing elements. Ko etahi o nga tohu rino he mea nui ano hoki he MN, Cu, me W. Kr, NI, NI, a ka taea e Mo te whakapai ake i te aukati. Its resistance to pitting and crevice corrosion is particularly good in chloride-containing environments.

Painga o te kowiri tira

1. whakataurite ki te kowiri tira

2) He pai rawa atu te paoho ki te aukati i te ahotea o te ahotea, ina koa i nga taiao kei roto i nga katote cloride. Ahakoa te kowiri tira ko te kowiri tira me te iti rawa o te ihirangi ka iti ake te ātete ki te aukati i te aukati i te kowhatu o te kowiri kowiri. He raru te ahotea o te ahotea ko te kowiri tira ko te kowiri tira he uaua ki te whakaoti. 3) The corrosion resistance of the most common 2205 duplex stainless steel used in many media is better than that of ordinary 316L austenitic stainless steel, and super duplex stainless steel has extremely high corrosion resistance. In some media, such as acetic acid and formic acid, it can even replace high-alloy austenitic stainless steel and even corrosion-resistant alloys. 4) He pai te parekura o te rohe. Compared with austenitic stainless steel with the same alloy content, its wear corrosion resistance and corrosion fatigue resistance are better than austenitic stainless steel. 5) The linear expansion coefficient is lower than that of austenitic stainless steel, close to that of carbon steel, suitable for connection with carbon steel, and has important engineering significance, such as the production of composite plates or linings.

2) Haunga mo te aukati i te aukati i te aukati, he pai ake te parekura o te rohe o te rohe i te kowiri tira.

3) Ko te mahinga tukatuka makariri me te mahi makariri nui he pai ake i te kowiri tira.

4) He pai ake te mahinga mahi i te kowiri tira. Ko te tikanga, kaore e pai te whakarite i mua i te tiimatanga me te kore maimoatanga wera e hiahiatia ana i muri i te raima.

5) He nui ake te whānuitanga o te tono i te kowiri tira kowiri.

Puka tono

Na te kaha o te kowiri tira, ka taea e ia te penapena rauemi, penei i te whakaiti i te matotoru pakitara o te paipa. Tangohia a Saf2205 me te Saf2507W hei tauira. He pai te whakamahi i nga taiao o te chlorine. He pai tenei rauemi mo te whakatikatika hinu, ki etahi atu mahi pāpāho ranei i konatunatua ki nga tiihi. He tino pai te whakamahi a Saf2205 mo nga kaihoko wera e whakamahi ana i nga kohinga wai-a-wai, te wai tote ranei hei pāpāho. He pai hoki te rauemi nei mo nga rongoā waikawa whanariki me te waikawa organic parakore me o raatau ranunga. For example: oil pipes in the oil and gas industry: crude oil desalination in refineries, sulfur-containing gas purification, wastewater treatment equipment; nga punaha whakamahana ma te whakamahi i te wai tote, te rongoa ranei-a-kara ranei.
