There are various types of body materials for smart water meters. At present, the mainstream smart water meters on the market are made of brass and ductile iron. However, engineering plastics, stainless steel castings, and cast aluminum alloy bodies are also used. Here is a brief introduction to everyone of these types of smart water meter body materials.
1. Engineering plastics :
Main features: easy to manufacture; non-toxic and non-polluting; corrosion-resistant, non-rusting, non-scaling, sanitary and environmentally friendly; lightweight.
Existing problems: low mechanical strength, insufficient rigidity, cold brittleness, easy aging, creep, etc.
2. Stainless steel castings :
Main features: acid and alkali resistance, no secondary pollution; no corrosion and exudation under high and low-temperature conditions, sanitation and environmental protection; good mechanical properties.
Existing problems: difficult to process and high manufacturing cost; currently, mass production capacity has not yet been formed.
3. Cast aluminum alloy :
Main features: abundant raw materials and low cost; good mechanical performance; high-cost performance and low production cost.
Existing problems: under the action of impact force, the surface hardened layer of threads and other parts are easy to peel off and damage; whether the precipitates after surface oxidation will be harmful to human health needs to be evaluated; the prediction and evaluation methods of body corrosion trends are still under study.
