Product Description

Product Description

I. General Characteristics

PVC oxygen&acetylene twins welding hose is a high-performance hose specially designed for for the transportation of oxygen and acetylene gas and welding, using high-quality polyvinyl chloride (PVC) and polyester fiber as the basic raw materials, combined with advanced technology manufacturing. The product is equipped with two independent gas channels, which can deliver oxygen and acetylene gases at the same time to meet the needs of welding, cutting and other operations. Its outer surface is wear-resistant, aging-resistant and corrosion-resistant, adapting to a variety of complex working environments, guaranteeing the safety and stability of gas conveying, and effectively prolonging its service life.

II. Structure

1. Three PVC layers structure: 

the inner layer adopts specially formulated PVC material, which has good air tightness and chemical stability; 

The intermediate PVC layer is effectively bonding the two layers of fiber-reinforced layers; 

The outer layer has excellent scratch resistance, acid and alkali resistance and UV resistance.

2. Double fiber reinforced layers design:

two layers of high-strength fiber threads are evenly distributed on both sides of the middle adhesive layer, which greatly improves the tensile strength and tear-resistant performance of the hose. At the same time greatly improve the pressure resistance of the hose.

3. Dual independent gas supply hoses:

two independent gas delivery hoses are glued together to deliver oxygen and acetylene respectively, avoiding gas mixing, and  it is more convenient.

III. Advantages

III. Advantages

- Convenient to use: 

 soft material makes the hose easy to bend and store, light weight reduces the burden of the operator; clear color marking (usually blue for the oxygen channel, red for the acetylene channel) facilitate quick identification and connection; highly adhesive to facilitate the use of the work to improve efficiency.

- Strong durability:

the outer PVC layer with wear-resistant, aging-resistant and corrosion-resistant can be used stably for a long period of time in harsh environments such as high temperature, humidity, dust, etc., which reduces the frequency of replacement and saves costs.

- Safe and reliable:

excellent air tightness and flame retardant properties, together with the dual independent air transportation design, effectively reduce the risk of gas leakage and explosion from the source; 
the double fiber reinforced structure enhances resistance to external forces and reduce accidental damage.

 

- High economy:

long service life and stable performance, reducing the cost associated with frequent replacements, with high overall cost-effectiveness.

Application

Application Fields

Widely used in metal welding, cutting and processing fields, such as machinery manufacturing, steel structure engineering, automobile repair, shipbuilding, pipeline installation, construction engineering and other industries. 

It is the ideal choice for all kinds of welding and cutting equipment to connect the gas source.

At the same time, it is also suitable for small gas welding operations, crafts production and other scenes.

Usage Specification

1. Pre-installation inspection:

Need to carefully check the surface of the hose for damage, cracks and other defects before use, and confirm that the joints at both ends are well sealed.

2. Correct connection:

Connect the oxygen and acetylene gas convey hose and equipment strictly according to the color marking, and strictly prohibited from making incorrect connections.

3. Use environment:

Avoid using near high temperature, open flame and sharp objects to prevent the hose from being scalded or cut; do not immerse the hose in corrosive liquid.

4. Pressure control:

Don't use the hose beyond the specified working pressure.

5. Daily maintenance:

Clean up the dirt on the surface of the hose in time after use, store it properly, avoid folding and heavy pressure; regularly test the hose for air tightness and replace it in time when problems are found.
