Industrial hose


Different from hard pipes, industrial hoses also have the characteristics of excellent flexibility. Compared with civilian hoses, the industrial operating environment is more complicated and harsher, and the equipment has more stringent requirements on the delivery pipe, so it is important to understand the characteristics of the hose. Industrial hoses have a wider range of sizes, a wide range of pressure and temperature, and higher chemical resistance.

Classification of industrial hoses


PVC polyvinyl chloride pipes. The characteristics of polyvinyl chloride pipe are chemical resistance, lightweight, no staining, no deformation, and anti-colic.


PVC pipes

PUR polyurethane tube. Polyurethane tube has the characteristics of chemical resistance, lightweight, and good wear resistance.


NR natural rubber. The rubber tube has elasticity, frost resistance, abrasion resistance, tear resistance, dilution acid resistance, low-temperature water and alcohol resistance, but weak chemical resistance.


And SBR oil-extended styrene-butadiene rubber, EPDM ethylene propylene diene rubber, NBR acrylonitrile butadiene copolymer/ nitrile, CR chloroprene polymer/rubber, SI silicone rubber, UPE/XLPE cross-linked polyethylene, etc.

How to determine the optimal connection and fastening method

Determining what kind of industrial hose clamp needs to determine the inner diameter, outer diameter, length, and tolerance of the hose in advance. In order to select the appropriate industrial hose clamp size.

Make sure that your circulating medium is liquid, solid, or chemical composition, and determine the materials and precautions used in industrial hose clamps.

Determine the working pressure and burst pressure of the hose to choose the strength and type of industrial hose clamp.

Other parameters to be considered

The weight, elasticity, bending radius, conductivity, flexibility, and smooth surface of the hose need to be taken into consideration. Which type of structure is it, steel wire weaving, fiber weaving, multi-layer synthetic fabric, or other materials, so that the optimal connection and fastening method can be selected later.

Choose the way of hose clamp connection, the advantage of metal hose clamp is increased strength. However, this does not guarantee that it will not deteriorate over time, and depending on the environment in which it is located, the severity of corrosion will be more or less. Metal hose clamps are divided into six categories according to their composition (W1 to W5 according to DIN 3014), and each category has its own level of corrosion resistance. In order to make the right choice based on the intended use of the metal hose clamp, it is necessary to understand its corrosion resistance level, which will tell you if it is prone to rust and when it will rust.

If the hose clamp exerts constant pressure on the hose, holds it in place, and prevents any risk of leakage, the hose clamp will work. The hose and the hose clamp to be applied must be optimally matched. If the clamp is too large for the diameter of the hose, the clamp will tend to relax when the pressure in the hose is high. On the contrary, if it is too short, too much pressure will be applied to the hose, which may damage the hose. Carry out accurate measurements to avoid potential safety hazards.

No matter whether they are used to transport compressed air, non-corrosive contrary, or corrosive liquids. 

Understand the types of industrial hose clamps

Industrial hose clamps are also known as heavy-duty hose clamps, generally divided into the following types:

high torque hose clamps, constant-torque clamps, t-bolt hose clamps, spring loaded t-bolt clamps, v-band hose clamps, robust clamps (high strength clamps), one bolt hose clamps, double bolt hose clamps.

How to choose an industrial hose clamp

Industrial stainless steel clamps have good sealing performance. As the fluid pressure in the pipe increases, its sealing response is strengthened. It has the advantages of anti-shock, anti-shrinkage, and expansion, and has stronger stability compared with welding and flange adjacent.

The industrial stainless steel clamp adopts a unique sealable structural design, so that the grooved connector has a good sealing performance, and as the fluid pressure in the pipe increases, its sealing performance is correspondingly enhanced.

Because the stainless steel hose clamp is made of high-quality steel, the production process is relatively good. It is safe and reliable after multiple strict checks when leaving the factory. It has strong anti-rust and tightening capabilities, and is very durable. The product has a beautiful appearance, convenient operation, high free torque, and overall torque. The edge of the hose clamp is smooth and does not damage the hose. The screw is fast and the hose clamp can be reused. Therefore, stainless steel hose clamps are mainly used for connecting soft and hard pipes and are widely used in the joints of oil, gas, and liquid hoses on automobiles, diesel engine, and other equipment.

For large-size hoses such as conveying hoses and sewage hoses, strong hose clamps should be selected. This type of hose requires more powerful torque and needs to be dragged frequently during the operation. Strong hose clamps can meet this working environment.

Large-size thick-walled silicone tubes are often seen on large trucks, such as transport vehicles, engineering vehicles, semi-trailers, and other large vehicles. The intake pipe of this high-horsepower engine is thicker and larger in size, so it needs to be equipped with stainless steel strong T Type hose clamp, the thread of the hose clamp is the same as that of ordinary screws. It has a strong torque. The stainless steel T-type strong hose clamp steel belt is three-point welding, so it ensures a strong locking ability. This large-size air intake thick-walled silicone tube is equipped with a stainless steel T-type strong hose clamp, which is both beautiful and can be locked and sealed. Therefore, it is recommended that this kind of silicone tube choose a stainless steel T-type strong hose clamp.

Large-scale powerful hose clamps mainly increase the fastening endurance, which greatly meets the requirements for fastening large pipelines. It is mainly used for large pipelines such as petroleum pipelines, ship pipelines, marine pipelines, and some chemical vehicles, and various factories. This kind of hose clamp.

Heavy-duty hose clamps are used at the joints of oil and steam pipes of large mechanical equipment such as automobiles, ships, aircrafts, etc. Generally, the pipes are thicker or require a strong fastening force.
