In special climates and working conditions, welding equipment is severely tested, but Derkia’s Flashback Arrester can solve such problems,
In which special environments can DERKIA’s products be used without being affected?
1. High temperature and UV resistance:
DERKIA Flashback Arrester’s products (including valve bodies, seals, and markings) withstand long-term outdoor high temperature exposure above 50 ° C without aging, cracking, or performance degradation.
The valve body material (such as high-quality brass or stainless steel) and sealing material (such as Viton’s similar quality fluororubber) are materials designed for high temperatures. The working temperature range covers extreme temperatures on site (such as -20 ° C to+80 ° C).
2. Dust and Corrosion Protection:
In desert areas, the invasion of fine sand and dust is a huge threat. DERKIA’s Flashback Arrester focuses on the sealing design of FBA, which can effectively prevent sand and dust from entering the internal core (flame retardant core, valve core), avoiding blockage or wear.
3.High salt spray corrosion in coastal areas.
DERKIA’s Flashback Arrester product adopts a higher level of anti-corrosion treatment (such as passivation, nickel plating, or stainless steel material). Special marine grade stainless steel (such as 316L, 317L) with passivation treatment can be specified according to customer specifications.
4. High dust environments (such as mines, cement plants, grain processing)
These work environments are prone to clogging of flame arresters: dust (especially metal dust, flammable organic dust) will gradually clog the pores of the flame arresters, leading to a sharp increase in pressure drop, insufficient flow rate, and the possibility of spontaneous combustion. The phenomenon of stuck moving parts and dust accumulation may cause the check valve to fail to close properly. DERKIA installs high-precision gas filters upstream of FBA, and if users clean them regularly, the above adverse phenomena will not occur. DERKIA also offers FBA with detachable and easy to clean flame retardant cores to meet the needs of different customers.
5. High traffic and continuous operation requirements:
For example, large-scale projects have tight schedules and high welding intensity. FBA needs to have a high rated flow rate and extremely low pressure drop to ensure flame stability during long-term, high flow gas supply, and the equipment itself will not become a bottleneck. DERKIA’s Flashback Arrester can achieve special operations, such as acetylene, with a rated flow rate of 25 Nm ³/h and a maximum pressure drop of 30 mbar at this flow rate.
Flashback Arrester is not only a security feature, but also an “industrial component” that needs to survive reliably in this environment for a long time. Its materials and design must first resist environmental erosion before reliably performing safety functions throughout its lifecycle.
