Several types connection of hose
Clamp connector connection
pressure range :250 800 Bar
Applicable steel pipe size range :4 - 42 mm
Suitable material: carbon steel and stainless steel sleeve type pipe joint is composed of three parts: joint body sleeve sleeve nut when the sleeve and nut sleeve are inserted into the joint body on the steel pipe, tighten the nut, the outer end of the sleeve and the conical surface of the joint body, the inner edge evenly bite into the seamless steel pipe, forming effective sealing advantages:
widely used and mature
Relatively low price of components
No special machine
Disadvantage:
only suitable for 42mm below the pipeline connection
Not suitable for thin-walled pipe
Large installation space and torque are required during installation
Not suitable for high safety conditions.
JIC37 degree joint connection
pressure range :420 Bar(250 Bar,100 Bar)
Applicable steel pipe size range :6 - 38 mm
Applicable material: carbon steel stainless steel brass copper alloy JIC37 degree of joint connection consists of three parts: joint sleeve nut when bushing and nut after the steel pipe, with flaring equipment in steel slapping forming, the joint body and the nut tighten again, through the cone interface rigid seal and O ring seal advantages:
wide application mature
Wide range of applicable materials
Simple and convenient installation.
Disadvantages of repeated disassembly:
only applicable to the pipeline connection of less than 38mm
Low nominal pressure (except DNV standard)
Not suitable for thick wall pipe
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 connection is the replacement of the connection mode by the sleeve joint connection.
After the female is set into the steel pipe, the forming equipment is used to automatically extruder the steel pipe end. After being loaded into the sealing ring, the joint body and the nut are tightened, and sealed by the rigid seal and sealing ring between the joint body and the forming surface Advantages:
Low torque and safe installation
The production process is quick and simple
Advanced technology without leakage
Disadvantages of repeated disassembly:
only applicable to the pipeline connection below 42mm
Socket welding connection
pressure range :420 Bar(only for small pipe diameter)
Applicable steel pipe size range :6 - 150 mm
Applicable materials: carbon steel and stainless steel socket welding connection is to extend the pipe into the valve body for welding, forming and internal thread connection appearance similar advantages:
widely used
Low component price
Advanced technology without leakage
Disadvantages:
need for skilled welders
Good ventilation and fire prevention measures are required for welding equipment
Require special cleaning and anti-corruption treatment
Butt welding connection
pressure range :500 Bar(only for small pipe diameter). Applicable steel pipe size range :6 - 608 mm. Applicable materials: carbon steel and stainless steel butt welding flange connection and butt welding joint connection advantages:
widely used
Low component price
Advanced technology without leakage
Simple pipe-to-pipe connection
Disadvantages: the need for skilled welders
Good ventilation and fire prevention measures are required for welding equipment
Require special cleaning and anti-corruption treatment
It will lead to environmental pollution
