Steel roller rings/steel insulators placed in concentric or eccentric positions act as spacers between the pipe and casing pipes to facilitate pipe installation by reducing friction between the carrier pipe and the casing and ensures electrical isolation of both pipes.
Benefits of Steel Roller/ Steel Insulators
Steel roller/ Steel insulators can tolerate high-medium temperatures.
Load-bearing capacity is more compared to plastic insulators
Rollers for rough casing pipe surfaces
Can be used for long distances
Wide or narrow diameter difference between the casing and carrier pipes.
Can be used as multiple pipes in exact defined position
Used for permanent pipe-movement
Integrated tensile protection
Used for hanging construction
Assembly:
Steel insulators are assembled by clamping together two halves which are individually manufactured, using hexagon nuts and bolts.
Ring halves and skids are made of steel. The surfaces are available without corrosion protection (black), or bitumen coated, plastic-coated, hot-galvanized, or in stainless steel.
Wheels made of polyamide, steel, or stainless steel. Sliding parts made of PP, steel, brass, etc. bolts made of galvanized, high-strength steel or stainless steel. Varying skid heights on both, the upper and the lower ring halves allow for any media pipe position inside the casing.
Guiding rails can be used for torsion protection in long distances.
Steel roller rings for single or multiple pipes.
Roller ring with holding clamp for socket joints.
Tie bar system ( roller ring fixed at one side and clamping ring on other side of the socket are tied using tie bars) may be used to ensure tight socket joints.
Factors to be considered:
• Insertion length
• Outer diameter of pipe
• Socket outer diameter
• Weight of carrier pipe
• Casing pipe inner diameter
• Sketch of carrier pipe position
• Type of media
• Type of connection between carrier pipe segments
• Length of individual carrier pipe segments
• Information if uplift protection if required
• Information if rotation protection is required
