Classification of low-pressure hoses
1. Use of steam hose: It is used for conveying saturated steam or superheated water at165℃ ~ 220℃, and is suitable for hot pressing equipment such as steam sweeper, steam hammer, flat vulcanizer and injection molding machine as soft pipes.

Features: Both the inner and outer rubber layers of the rubber hose are made of synthetic rubber with excellent heat resistance, and the tube body has the characteristics of softness, portability, good flexibility and high heat resistance. Saturated vapor pressure of braided layers of steel wire with inner diameter of mm

MPa(kgf/cm2) corresponds to the minimum bending radius.

Mm corresponds to the reference outer diameter.

Mm corresponds to reference weight.

According to the requirements, we can manufacture large-caliber (below φ 102mm) and small-caliber (above φ6mm) steel wire woven steam hoses, high-temperature and high-pressure steam hoses and steam hoses with various specifications above φ 13mm, and ultra-high temperature (260℃) corrosion-resistant high-pressure PTFE hoses.

Steam pipe type

A, cloth steam hose:

1, Application: Suitable for conveying saturated steam or superheated water at a temperature not higher than 150℃.

2. Features: The adhesive layer has good heat resistance, and the bursting pressure of the hose is not lower than 10 times of the working pressure.

Armored cloth-sandwiched steam hose:

1, Application: Suitable for conveying saturated steam or superheated water at a temperature not higher than 150℃.

2. Features: The outer surface of the rubber hose is wrapped with galvanized metal spiral, which can effectively increase the strength of the pipe body and improve the bearing capacity. It is suitable for occasions with complex working conditions and high requirements for safe operation.

Second, the tetrafluoride tube:

1, uses: widely used in chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, pipelines, petroleum, textile machinery, electrical insulation, environmental protection and other economic fields.

2. Features: fine appearance, high strength without mechanical impurities, excellent chemical stability, corrosion resistance, sealing, self-lubricating and non-stickiness, electrical insulation and excellent anti-aging ability. It can be used for a long time at-60 ~ 250℃ and has reliable and excellent corrosion resistance. It is used to transport strong corrosive media at high temperature. And can be processed into O-shape, S-shape, □-shape and other shapes, and the quality is guaranteed.

(1). High temperature resistance, corrosion resistance and high pressure resistance.

Because this product adopts special high-grade PTFE hose, high-temperature resistant woven net and Japanese advanced technology stainless steel double-buckle spiral hose, it is suitable for special environment with high temperature, corrosion and high pressure.

Under the pressure of 3kg/cm2, this product can withstand the high temperature steam of 250℃ inside the hose, and the skin temperature does not exceed 60℃, ensuring the safety of operation.

This product can be used normally under the steam pressure of 10kg/cm2.

⑵. Light weight and strong flexibility.

This product has been specially assembled, and the hose with a total length of 2m (including the joints at both ends) only weighs 500g. Greatly reduce the working intensity of operators, and at the same time, it has strong softness and free bending, and absolutely does not break the pleats to hinder ventilation.

(3). Strong destructive resistance

This product is protected by Japanese advanced technology stainless steel double-buckle self-locking spiral hose, which can bear the tension of 180kg, and it will never be damaged during normal use.

(4) Durable

Combining the advantages of this product, the service life of this product is much longer than that of existing steam hoses, and it is not necessary to replace it after long-term use, which greatly reduces the use cost, improves the use efficiency, and is economical and practical.

Three, stainless steel pressure metal hose:

1, uses: widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, electric power, paper making, wood, textile, construction, medicine, food, tobacco, transportation and other industries.

2. Features: corrosion resistance, high temperature resistance, low temperature resistance (-196℃~+420℃), light weight, small volume and good flexibility.

Four, silicone tube:

Any length within the range of 4-50MM in diameter is cold-resistant, high-temperature-resistant, non-toxic and tasteless, which conforms to food hygiene, and the silicone tube with glass fiber is more moisture-proof and pressure-resistant. It can withstand the temperature of 300℃, and its main specifications are internal diameter of 9.5 and 12.7, wall thickness of 3.5 and pressure of ≤0.3MPa. It is used for the peristaltic pump mouth to roll the pump tube through the pump head to generate vacuum and drive the liquid to flow. Cloth-sandwiched hose This product includes oil hose, steam hose, sandblasting hose, acid-base hose, food hose, oxygen hose and other special-shaped hoses.
