A27 cable protector cast cable protector clamps
The introduction of the cast steel cross coupling protector to the oil and gas industry in the mid 1980`s served to revolutionise the protection of downhole cables used to power electric submersible pumps (ESP`s), safety valves and other downhole equipment. Historically, damage to downhole cables due to crushing between the production tubing couplings and the casing internal diameter cost the industry millions of pounds in unscheduled workovers and recompletions. The North Sea is one of the most hostile of environments, but today, cable damage is virtually unheard of. This is directly attributable to the introduction of cast steel cross coupling protectors. During the past ten years, the cast steel cross coupling cable protector has been introduced throughout the world`s oil and gas producing regions and from its humble beginnings in the North Sea is now protecting downhole cables from mechanical damage in thousands of oil and gas wells on land and sea throughout the world.
Wei fang jun long Ltd offers a full range of all metal cross coupling cable protectors with robust cast steel bodies to the oil and gas industry. This new range of cable protectors has been designed with total protection in mind and incorporates some new design features which place it ahead of the competition with regard to cable protection.
Features:
- All metal cross coupling construction to NACE specification MR01-75/95 for sour gas service.
- Improved cable guard `stand off` to minimise potential for damage due to crushing.
- Improved contouring of leading edges to `deflect` away from potential hang up situations.
- Alignment of capscrew head with protective rib to substantially increase wear protection for the vulnerable capscrews.
- Interlocking action between clamping arm and casting body to eliminate potential shear stresses on the capscrews.
- Low profile clamping arm shielded from hang up by coupling offset and casting body.
- One piece assembly with no loose fittings to fall downhole.
- Pre-engaged fasteners throughout the range for fast and reliable installation to reduce rig time required.
- Totally retrievable and re-usable with the minimum of refurbishment
