Product Description

Product Description

I. Core Product Overview

PVC oxygen&acetylene twins welding hose with 3 layers of PVC and 2 layers of fiber reinforcement is a high-performance hose designed for industrial gas transmission. It is made of high-quality polyvinyl chloride resin and high-strength polyester fibers, and is manufactured through advanced composite technology. The product adopts the parallel structure of double hose, which can transmit oxygen and acetylene gases at the same time, and is perfectly suited for all kinds of welding and flame processing scenarios. The surface of the product is treated with special technology, which has excellent wear-resistant, anti-aging and corrosion-resistant properties, and it can also stably deliver gases even in harsh industrial environments, greatly enhancing operational efficiency and safety.

II. Details Of Product Structure

1. Three-layer PVC composite hose wall: 

the inner layer adopts gas-barrier PVC layer, which effectively prevents gas leakage; 

the middle layer is the elasticity enhancement layer, which makes the hose flexible and compression-resistant; 

the outer layer is the modified PVC protection layer, which is weather-resistant, can resist acid and alkali corrosion.

2. Double-layer fiber reinforced structure: 

the double-layer high-strength fiber mesh is symmetrically distributed on both sides of the PVC middle layer, which significantly enhances the strength of the hose.

3. Dual gas path parallel design: 

two independent gas delivery hoses are tightly fused by heat fusion process. Oxygen and acetylene channels run separately and are clearly marked in red and blue, which not only ensures the safety of gas delivery, but also facilitates quick identification and connection.

III. The Advantage And Highlights Of Product

III.  The Advantage And Highlights Of Product

- Excellent safety performance: 

independent dual gas circuit design fundamentally eliminates gas leakage and mixing hidden dangers; flame retardant and explosion-proof materials guarding operational safety all-around.

- Wide environmental adaptation: 

the working temperature range is from -15℃ to 65℃, with outstanding oil and cold resistance, applicable to metallurgy, shipbuilding and other extreme environments, and the annual loss rate is reduced by 60%.

- Convenient and efficient operation:

the hose is lightweight and easy to bend, and can be stowed with one hand; the standard quick-plug connector increases the connection efficiency by 50% and reduces the downtime.

 

- Strong economic durability: 

high-quality weather-resistant raw materials to extend the product life to two times that of ordinary products, reducing the overall cost of use by 35%.

Application

Expansion Of Application Fields

It is suitable for heavy industrial manufacturing such as machining and pressure vessel welding, infrastructure construction such as bridge building and pipeline laying, and transportation maintenance such as automobile dismantling and ship repairing.

Meanwhile, it can also be used in jewelry processing, glass blowing and other fine gas welding operations to meet the needs of different scales and precision operations.

The Usage Specification

1. Installation requirements: 

Pressure test should be carried out before use to ensure that there is no leakage, and special clamps should be used to fix the joints.

2. Precautions:

Avoid contact with sharp objects, do not drag next to energized equipment, gas temperature control between -15 ℃ and 65 ℃.

3. Maintenance:

Check the gas tightness every month, check the condition of the fiber layer every quarter; when not used for a long time, the air inside should be released. Store it rolled up in a dry and cool place.
