Do you know how hydraulic hoses are connected and their pros and cons(2)?

3. End forming connection (Walform) - Pressure range: 250 – 800 Bar; Applicable steel pipe size range: 4 – 42 mm; Applicable materials: carbon steel, stainless steel, copper alloy, etc.
Walform connections are an alternative to compression fittings. After the female sleeve is inserted into the steel pipe, it is automatically extruded and formed at the pipe end of the steel pipe with the forming equipment. After the sealing ring is installed, the joint body and the nut are tightened, and the rigid seal of the joint body and the forming surface and the sealing ring are used to seal.

Advantages: low torque and safe installation; fast and simple production process; advanced technology and no leakage; repeatable disassembly and assembly.

Disadvantages: only suitable for pipeline connections below 42mm; need to form the end of the forming equipment.

4. Socket Weld Connections - Pressure Range: 420 Bar (Small Pipe Diameter Only); Applicable Steel Pipe Size Range: 6 – 150 mm; Applicable Materials: Carbon Steel and Stainless Steel. The socket welding connection is to extend the pipeline into the valve body for welding, and the shape is similar to the internal thread connection after forming.

Advantages: Wide range of applications; low price of components; advanced technology and no leakage; simple connection method for low-voltage systems.

Disadvantages: Requires skilled welding workers; requires welding equipment, good ventilation and fire prevention measures; requires special cleaning and anti-corrosion treatment; will cause environmental pollution.

5. Butt Welded Connections - Pressure Range: 500 Bar (Small Pipe Diameter Only); Applicable Steel Pipe Size Range: 6 – 608 mm; Applicable Materials: Carbon Steel and Stainless Steel.

There are butt welding flange connections and butt welding head connections.

Advantages: Wide range of applications; low price of parts; advanced technology and no leakage; simple pipe-to-pipe connection.

Disadvantages: Requires skilled welding workers; requires welding equipment, good ventilation and fire prevention measures; requires special cleaning and anti-corrosion treatment; will cause environmental pollution.
