How to judge the lining water coated lay flat hose?
The hoses on the market are usually divided into lined hoses and unlined hoses. At present, the most commonly used ones are lined hoses. There are three types of lined hoses. One is pvc lined hoses. , One is a polyurethane-lined hose, and the other is a synthetic rubber thickened lining hose, so what kind of lining hose is better?First of all, let's take a look at what are the lined hoses? In the hose market, there are three types of lined hoses: PVC lined hoses, polyurethane lined hoses, and synthetic rubber lined hoses. Model pressures are 8, 10, 13, and 16, with diameters from 1.5 to 8 inches. Not equal. Different materials, models and caliber characteristics are different, and the applicable operations are also different.
When we judge whether the water hose is good or not, we all judge by our own use, so it is the first point to determine our needs. For example, pvc lined hoses are mostly used for agricultural irrigation. If high pressure is required, type 13 and type 16 polyurethane hoses are used; industrial sewage and hot water supply use polyurethane lined hoses and synthetic rubber lined hoses, generally using polyurethane There are many lining hoses; flood prevention and drainage use large-diameter hoses, usually 6-inch 8-inch hoses.
Secondly, there is the issue of the quality of the lining hose. The quality of the hose should be considered from two aspects of the hose braid and the inner lining. At present, the high-strength polyester filament used in the hose tape skin is excellent in compression and explosion-proof performance, and the inner liner is made of high-quality gum, which is better in acid and alkali resistance, aging resistance, freeze resistance and high temperature resistance. We have some such tips when choosing a lined hose: check whether the hose skin is smooth and bright, whether there is a broken thread jump and loose weaving, use high-strength polyester filament hose to check the composition of the braided wire Generally, a high-strength silk is composed of multiple filaments; check whether the gum of the hose is smooth, soft, non-toxic and tasteless, whether there is cracking and degumming, and whether there are obvious white marks on the gum of the bent hose.
Finally, the price is either cheap or good, or expensive, high-end, the real pursuit should be the highest cost performance to ensure the safety and stability of the operation for a long time. This is to consider the factors mentioned above and choose a hose suitable for you. Here I would like to remind everyone to choose the best water hose to regular quality manufacturers so that the quality and service are more guaranteed.
