1. Classification:

1. Fire hoses are generally divided into rubber hoses, rubber hoses, and polyurethane hoses according to their materials.

2. The fire hose can be divided into: DN50, DN65, DN80, DN100, DN125, DN150 according to the size

3. According to the pressure of fire hose, it can be divided into: 8 type, 10 type, 13 type, 16 type, 20 type, 25 type

4. Fire hoses can be divided into: agricultural water hoses, industrial hoses, fire brigade special hoses, etc.

2. Model details:

1. Model specifications are a series of indicators that reflect the nature, performance, and quality of the product. Generally, they are composed of a set of letters and numbers with a certain number of codes. Specifications and models must be standardized, accurate and detailed, so as to ensure accurate classification, clear statistics, and It is helpful for consumers to choose their own suitable products. The fire hose is basically composed of a woven layer, a lining and an outer covering layer, and each part can be composed of multiple materials. For example, the main material of the woven layer is generally synthetic fiber and cotton. The main materials of lining are rubber, latex, plastic coating and polyurethane, etc., so the naming method of model specifications has been added to the new standard. The model specification of fire hose is composed of design working pressure, nominal inner diameter, length, braided layer warp/weft yarn material, and outer covering material material.

2, the model of the hose (10 times the design working pressure), the unit is megapascals (Mpa). The nominal inner diameter of the hose, in millimeters (mm). The length of the hose, in meters (m). S stands for the logo of the wet hose. For example, the design working pressure is 1.0Mpa, the nominal inner diameter is 50mm, the length is 30m, the warp of the braid is made of polyester filament, the weft is made of polyester yarn, and the lining is made of polyurethane. The model should be expressed as: 10-50 -30-Polyester filament/polyester yarn-polyurethane/S.
