What are the USES and types of metal bellows?
1. As a sensitive element, shock absorbing element, compensation element, sealing element, valve element and pipe connecting element, pipe blank is widely used in automatic control and measurement instrument, vacuum technology, mechanical industry, electric power industry, transportation and atomic energy industry and other fields.
Usage: different metal materials are selected for different USES of the billet. Due to different materials, the properties and USES of the metal Corrugated Pipe processed are also different.
2, the tube billet is made of thin wall stainless steel with welded pipe waveform processing, with flexible and good temperature and pressure resistance.
Application: suitable for air, steam, all kinds of industrial gases, water, oil, drugs and other kinds of fluid medium.it plays an important role in reciprocating motion, thermal expansion absorption, vibration absorption, and center adjustment of piping system.
3, the metal bellows billet is the metal hose, Metal corrugated pipe China, bellows compensator, bellows billet, automobile exhaust pipe, high pressure rubber pipe, cable threading pipe and other pipe body supporting products, the use of metal bellows billet, divided into soft state, hard state two varieties, bright and soft, reliable quality, complete specifications. The product is corrosion-resistant and beautiful in appearance, which can improve the pressure bearing capacity of the finished hose, withstand high and low temperature force, the service life of the tube body and reduce the cost.
USES: widely used in machinery, chemical industry, metallurgy, construction and other industries.
How to solve the corrosion problem of metal bellows?
1. Mixed solution 1 was obtained by mixing 5-10 parts of ethyl orthosilicate, 0.6-1 parts of mercaptopropyl triethoxy silane, 5-10 parts of isopropanol, 3-5 parts of N, n-2 methyl formamide, 3-8 parts of ethanol and 1-3 parts of polyethylene glycol.
2. Mix 1-3 parts sodium silicate, 2-5 parts sodium hexametaphosphate, 1-5 parts maleic anhydride, 0.2-0.6 parts surface active agent, 0.2-0.5 parts antifoaming agent, 0.5-1 parts silicon dioxide and 10-20 parts water in weight to obtain the mixed liquid 2.
3. Heat the mixture liquid 2 to 30-40°C under the protection of inert gas, add the mixture liquid 1 in the state of agitation, stir for 20-30 minutes after adding, then add 0.5-1 part of diethanolamine and 0.2-0.6 part of acetic anhydride, continue stirring for 40-60 minutes, and bring it to room temperature to obtain the anticorrosive liquid for Galvanized corrugated metal pipe.
Corrosion of metal corrugated pipe, metal bellows fully into the above processing liquid, under the condition of 40-50 ° C keep 50 to 60 minutes, and then heated to boiling, 2-3 minutes can reach a good antiseptic effect, no any adverse impact on metal bellows, compared with untreated metal corrugated pipe, corrugated pipe anticorrosion performance improved obviously after treatment.
