Product Overview
This hinged split coiled tubing clamp is a dedicated load-bearing fixture widely used on coiled tubing operation sites. It is applied for hoisting coiled tubing from reels, temporary wellhead anchoring, load retention during bottom hole tool assembly and pressure testing. The clamp adopts hinged two-piece housing design for quick opening and closing; internal hardened serrated slip segments bite into coiled tubing outer wall to generate robust friction clamping force. When you tighten the outer bolts, the housing compresses slips radially to grip tubing tightly and transfer tensile/lifting loads; loosening bolts enables fast disassembly without threading the tubing through clamp ends.
The main housing is manufactured from heat-treated forged alloy steel with bright red anti-corrosion coating for outdoor rust prevention on rig floors. Worn slip inserts can be individually replaced instead of replacing the whole clamp to cut long-term operating cost. The hinge structure greatly accelerates on-site installation. Sour-grade variants follow NACE MR0175 / ISO 15156 standards to adapt to H₂S containing workover environments. It is a common auxiliary tool for coiled tubing rigs during rigging, tool string assembly and tubing maintenance.
Core Features & Benefits
- Hinged split housing allows mounting at arbitrary positions along coiled tubing, no need to thread pipe ends through the clamp
- Hardened serrated slip inserts provide strong anti-slip gripping, prevent tubing slippage under heavy tensile load
- Forged alloy body has excellent impact, bending resistance to adapt harsh rig site operating conditions
- Red epoxy coating improves outdoor corrosion resistance and provides high visibility for site safety management
- Modular replaceable slip inserts reduce fixture maintenance expenditure, extend overall clamp service life
- Matched high-strength bolts supply stable clamping preload, resist loosening caused by operation vibration
- Custom inner bore dimensions to fit all mainstream coiled tubing outer diameters
- NACE-compliant sour service options for high-sulfur well operations
- Two structural configurations available: long hinged type for lifting, compact type for fixed clamping
- Properly distributed clamping force avoids excessive indentation, protects coiled tubing structural integrity

Typical Applications
- Lifting and transporting coiled tubing between reel and wellhead equipment
- Temporary tubing anchoring during assembly / disassembly of downhole tools
- Tension fixation of tubing ends during hydrostatic pressure testing
- Position clamping for coiled tubing cutting, welding and end modification
- Clamping operations for sour well workover projects
- Auxiliary positioning for coiled tubing injector units
- Securing coiled tubing segments during yard storage
Advantages Over Ordinary Strap / Cast Clamps
- Hardened slip gripping delivers far higher load capacity than flexible strap clamps for heavy lifting scenarios
- Hinged split installation works for middle sections of tubing, no requirement for pipe end penetration
- Forged body has far better impact resistance than cast clamps, extending service life on rough rig sites
- Replaceable slips lower recurring hardware procurement cost
- Protective coating slows rust formation under humid, muddy outdoor working conditions
- Optimized inner contour reduces tubing denting risk under rated clamping load
FAQ
Q: Can you produce clamps for non-standard coiled tubing diameters?
A: Yes, we customize inner bore size and matching slip inserts to fit special tubing dimensions.
Q: Are sour service compatible versions available?
A: We supply full NACE compliant body, slips and bolt hardware along with complete material test certificates.
Q: Can I purchase replacement slips separately?
A: Separate replacement slip packs are available for all models to reuse existing clamp housings.
Q: What is production lead time?
A: Standard in-stock sizes ship within 5–10 working days; customized coiled tubing clamps take 12–22 working days.
