Selection points of shower hose
Shower hose includes various metal hoses, braided pipes and PVC reinforced pipes. There are some differences between different materials. There is no absolute answer to which is better. You can compare several materials when purchasing. The key surface is flat, the gap is uniform, the hand feel is smooth, the key unfolds naturally, the structure is firm, and the damage resistance is strong. In addition, the specifications and dimensions of the shower hose shall be consistent. The general dimensions are 14 mm, 16 mm, 17 mm and 18 mm outside diameter. You can pick up the old hose and buy a new one for comparison.
1. look at the materials
Metal hose - high temperature resistance, corrosion resistance, thin-wall hydraulic forming, good flexibility and flexibility;
Braided pipe has certain price advantages, the lowest grade, easy to leak, oxidize and other problems;
PVC reinforced pipe - resistant to deformation, wear and external pressure.
2. see the attachment
Nut style: various nut styles;
Nut material: copper or stainless steel;
Joint material: copper or stainless steel.
3. see the specification
Hose structure: the structure is firm and passes the compression, tension and torsion tests.
Hose length: 1.2m, 1.5m, 1.8m, 2m.
Hose specification: 14mm,16mm,17mm and 18mm.
Surface treatment: electrolysis and electroplating
Inner pipe material: PVC silicone inner pipe, ternary inner pipe, etc.
4. look at the performance
It mainly depends on the surface flexibility and threaded connection of the shower hose, which is a very important point for a good shower hose, then the selection of joint material and leak proof effect, and finally the internal pipe. It is recommended to choose the ternary internal pipe with good flexibility and shrinkage.
Shower hose material selection details
1. the shower hose is the link connecting the hand-held shower and the faucet. The hose is generally composed of EPDM inner pipe, high temperature resistant nylon core and 304 stainless steel outer pipe. The nut is made of cast copper and the gasket is made of NBR. Ethylene propylene diene monomer (EPDM) is a copolymer, which is composed of ethylene, propylene and non conjugated diene solution. Then a friend asked, why do you use this kind of rubber as shower hose?
2. first of all, the aging resistance and superheat resistance are very good. EPDM has excellent weather resistance, ozone resistance, acid and alkaline resistance, etc. After soaking in 125 ℃ superheated water for 15 months, the mechanical properties changed little, and the volume expansion rate was only 0.3%. EPDM is the best material for hoses because it requires a long time of hot water to flow through the shower.
3. the second is elasticity. We all know that when using the hand-held shower, we need to constantly stretch to wash the body, and the EPDM molecular chain can maintain flexibility in a large range, and can also be kept at a very low position, so this is one of the main reasons why designers choose EPDM.
When purchasing a shower set, stretch the hose as much as possible and check the elasticity of the hose. Generally, the better the elastic property, the better the rubber material used for product description. The braided nylon core is usually made of plastic coated acrylic fiber to protect the inner tube. 304 stainless steel outer tube is wound with stainless steel wire to protect the inner tube, limit stretching and prevent explosion. Even if some manufacturers' products are marked with stainless steel skin, they are not stainless steel. Be sure to pay attention to this point when purchasing, and check whether the rebound after stretching returns to the original position.
