A few kinds of commonly used plank of stainless steel cistern compare?
Classification：Tank encyclopedia 2019-05-21
At present on market the most common a few kinds of stainless steel cistern, its stainless steel plank has roughly: 304, 316, 444, 201. Generally speaking, the stainless steel tank is often used SUS304 plate, 316 plate is mostly used in the case of poor water quality, 444 plate in the coastal area more use. As to 201 plank, should not be used, but because its price is cheap, often be used secretly by the illegal profiteers that a few are greedy, figure small profit. Several material characteristics are compared as follows:
I. SUS304 has good corrosion resistance, heat resistance and rust resistance. Non-magnetic, excellent processing and welding performance, strong corrosion resistance to oxidizing acid, alkali and most of the organic acid and inorganic acid also have a certain corrosion resistance, is the most conventional and extensive choice of water tank manufacturing materials. (if it is a domestic drinking water tank, food grade 2B board must be used).
Ii. SUS316 has good welding performance and pitting resistance, especially excellent high temperature strength and intergranular corrosion resistance; At the same time, it also has good resistance to chloride erosion, better corrosion resistance than 304 in seawater and other media. So it is usually used in Marine and chemical industrial environment and other harsh conditions. But its market price is high, can only according to the actual needs of selective use.
Three, SUS444 is a high corrosion resistant ferrite stainless steel, high yield strength, strong magnetic. Compared with other stainless steel, the biggest advantage is strong resistance to chloride ion stress corrosion cracking ability, its resistance to chloride ion point corrosion ability is better than SUS304, and SUS316L is comparable, more suitable for the city water supply tank in coastal areas. But its corrosion resistance is not strong (easy rust), not as good as 304 plate, but the price is cheaper than 304 plate, according to the actual need to choose.
Four, SUS201 is low nickel stainless steel, service life is short, corrosion resistance is poor, easy to rust, especially acid, easy to corrosion, with its water tank quality is not guaranteed, endless future. Plus it's high in manganese, which makes it especially harmful to your health as a drinking water tank. But as a result of 201 cheap prices are often a number of cheap, small profit illegal profiteers secretly used. We suggest not.
Excellent and durable materials: choose excellent austenitic, ultra-low carbon, ferritic stainless steel plate made. Anti - seismic, anti - crack performance is good, all year round anti - corrosion. Reasonable structure and easy installation: high strength stamping plate and evenly distributed stainless steel bars in the box increase the strength of the box by six times, and the force is even. The water tank is composed of rectangular plates and concave and convex plates assembled and welded together, which is easy to install and transport without large lifting equipment, and can be assembled on site with different volumes.
Stainless steel water tank plate surface using imported corrugated steel bar rolling machine to form corrugated reinforcement bar, greatly improve the skin strength and capricious, prevent water pressure caused by high deformation of the tank.
Integration of stainless steel water tank inside the water tank welding, this place is the key of the circular tank quality key, a small manufacturer due to the imperfect equipment, in this link is the hand stitch welding, hand stitch welding is easy to appear problem, the leakage welding and welding is not complete, repair welding is very common, and stainless steel water tank use 2 years to guarantee the quality and large water supply equipment adopts full computer pulse straight seam welding, high frequency protection weld beautiful and easy, strong, strong tensile property, secondary processing and greatly enhance anti-corrosion effect, perfect welding process, to remove water vapor into the foam layer to reduce heat preservation effect.
