Red and Blue Oxygen and Acetylene Hoses for High Pressure Welding Equipment

Product Description

Product Description

I. General Characteristics

PVC three layers of PVC and two layers of fiber reinforcement acetylene hose is a high-performance hose designed for acetylene gas transportation, with excellent comprehensive performance. The product is made of high-quality polyvinyl chloride (PVC) and fiber as the main raw material, combined with advanced production technology, with good flexibility, abrasion resistance and aging resistance, it can stably transfer gases such as acetylene under various complex working conditions, ensuring safe and efficient use.

II. Structure

- PVC inner thicken layer:

It has been thickened and comes into direct contact with acetylene gas, with excellent chemical stability,ensuring the purity of the gas and the safety of transportation.

- Two-layer fiber reinforcement: 

These are braided on both sides of the middle PVC layer, improving the hose's pressure-bearing capacity and tensile properties, to prevent the hose from bursting or deformation in high-pressure environments.

- PVC middle transition layer:

Located between the two layers of fiber reinforcement layer, plays the role of adhesion and buffer.

- PVC outer weather resistance layer:

It is made of wear-resistant and weather-resistant PVC material with special treatment on the surface, which has good anti-slip and tear-resistant properties.

III. Advantages

III. Advantages

1. High safety:

The unique three layers of PVC and two layers of fiber reinforcement structure design has excellent pressure-bearing capacity, which can withstand 4.0MPa acetylene gas pressure, with a burst pressure three times the working pressure (12MPa). Moreover, the inner layer has strong chemical stability, effectively preventing gas leakage and reducing the risk of use.

2. Excellent economy:

The product is cost-effective, in order to ensure high quality and high performance at the same time, long service life, low maintenance costs, to save long-term cost of use for the user.

3. Good durability:

The outer layer has excellent wear-resistant, weather-resistant, anti-aging properties, can adapt to high temperature, low temperature, humidity, dry and other harsh environments, reducing the cost of frequent replacement of the hose. It can be used in a wide range of temperatures from -5°C to 65°C to maintain good performance.

4. Good flexibility:

The soft texture of the hose is easy to bend and coil, which is convenient for installation and laying in narrow spaces or complex hose layouts, reducing the difficulty of construction and improving work efficiency.

Application

Fields Of Application

1. Welding and cutting field: 

Widely used in all kinds of metal welding and cutting operations, as an acetylene gas conveying hose, it stably supplies gas to welding torches and cutting torches and is a commonly used consumable in industries such as mechanical manufacturing, shipbuilding, and steel structure processing.

2. Construction field: 

In the construction site, it is used in the welding and cutting operation of metal components.

3. Repair and maintenance industry:

Automobile repair, equipment maintenance and other scenes, to provide maintenance personnel with safe and reliable acetylene gas delivery channel, to meet the welding needs of maintenance operations.

The Usage Specifications

1. Installation requirements:

Before installation, ensure that the inner wall of the hose is clean and free of debris to avoid scratching the inner PVC layer; avoid excessive bending, twisting or being squeezed by sharp objects during the laying process.

2. Pressure limitation:

Check the gas pressure regulator before use, to ensure the product in strict accordance with the maximum working pressure labeled, prohibit over pressure operation.

3. Environmental conditions:

Avoid long-term use in high temperature (over 65℃), open flames or strong corrosive environment; if used in harsh conditions, appropriate protective measures should be taken.

4. Regular inspection:

Check the appearance of the hose regularly during use; if the outer PVC layer is found to be broken, bulging, leaking, etc., the hose should be stopped immediately and replaced with a new one.
