Host: 6 differences corrugated hoses for gas and water

Bellows hose, many considered the most reliable, but in my opinion this matter reserved. Products, of course, strong and serve more than 10 years, but not always easy. If you got a good brand-name, and it will last 20 years, provided that is properly installed and if No, you have to throw in a couple of years which has recently experienced due to too strong inflection.

Noticed that the producers a good eyeliner, not all true, indicate, how many times it is allowed to stretch. Yes, it turns out, and then do not be too confident and without need motylyat hose from side to side.

Differences between gas and water bellows

Outwardly, they are very similar, but some differences still highlight:

Water and gas bellows often designated stickers of different colors: Podvodke on the gas it is yellow, and the water - blue (blue). But the stickers in general can not be no, so it is usually not guided.

Type corrugations - this is the fundamental difference. water hoses running under higher pressure than the gas, so they are more rigid, and, accordingly less flexible. The water, as know used AiSi steel 304 or 304, and gas 316 mainly AiSi which is softer and more rigid steel therein only fittings.

Mounting fitting. Hose fitting for gas may be cast from aluminum or stainless steel and welded to the sleeve argon-arc welding. Such a connection, if you put it into the water, quickly eaten corrosion and hose end. On the water bellows fittings often zavaltsovyvayutsya, which significantly increases their reliability.
union nuts. Stainless nut and gas, and water I have no questions, if they are attached to the sleeve normally. The hose nut put into water not only stainless steel but also brass and bronze with nickel or chrome-plated.

Feature. Many water bellows equipped with locking ring for high-quality docking seamed edge corrugations through the seal with the pipes or other fittings.

And corrugated hoses to the water must have a confirmation, indicating the safety of the product when used for drinking water.

There are even hoses, fittings which are made of ordinary steel, carbon - China, probably. And they are welded to the corrugation of stainless steel! It is clear that at this juncture the trick will make electrochemistry and gradually destroyed. Not seen, but I heard that caught hose with fittings, soldered with tin, which is also unreliable. Well, the most powerful hit, which I was told is when fitting to the gas hose is glued corrugation - immediately and without words is clear.
