R12/13 4SP Braided Metal Hose is a high-pressure hydraulic hose, commonly used in oil pressure systems in industrial fields, oil and gas extraction, construction and mining equipment, and other applications that need to withstand high pressure. It consists of an inner tube, a winding layer, an outer shell and connectors.

R12/13 indicates the pressure rating of the hose, which can withstand pressures as high as 12,000 to 13,000 pounds per square inch. 4SP means the hose has four helically wound layers that provide extra support and strength allowing it to withstand higher pressures. The braided metal layer is usually made of stainless steel or other corrosion-resistant materials, which can provide higher wear and corrosion resistance, making it suitable for use in various harsh environmental conditions.

This kind of hose is usually resistant to wear, oil, high temperature and pressure, and can be used to transport various liquids and gases, such as water, oil, liquefied gas and air. When selecting and using hoses, attention should be paid to factors such as hose size, pressure rating, applicable medium, and use environment.

Braided metal hose is a hose braided with metal wires, typically used for high-pressure gas or liquid delivery, and applications in high or low temperature environments.

The following are the production steps of braided metal hose:

Preparation materials: need to use wire, metal pipe and braiding machine.

Make the inner metal tube: Twist the wire along the metal tube until a sealed metal tube is formed.

Braided wire: The wire is passed through the braiding machine and braided over the metal tube. The weaving machine can perform different types of weaving as required to meet different application requirements.

Fixing wire: The braided wire is fixed on the metal tube by pressure to ensure that the hose has sufficient strength and rigidity.

Testing and Quality Control: Various tests are performed to ensure that the hose is of the required quality, including pressure testing, burst testing, and abrasion resistance testing, among others.

The above are the production steps of the braided metal hose. The production of this kind of hose requires experience and professional skills, so it is recommended to do it with the help of a professional manufacturer.
