The Versa-Clamp® is designed to address 3 main issues for offshore tubing installations: Crevice Corrosion, Vibration, and Space Constraints. These 3 issues are present on just about every offshore installation, and the oil and gas industry has long sought ideas to address them.
Crevice corrosion occurs in crevices and other narrow spaces, especially where a choloride-bearing solution, such as seawater, can enter and be trapped. This problem is common to tubing clamps or supports that encapsulate tubing, restrict ventilation around contact points between the tubing and the support, and have a greater surface contact area between the tubing and the support. The risk of crevice corrosion can be reduced or problems eliminated through proper engineering design. The Versa-Clamp® offers minimum contact between the tubing and support, ventilation, and isolation of dissimilar metals.
Vibration can be detected in virtually any tubing installation, and tubing must be clamped firmly and maintain contact with the support. Conventional methods of supporting ubing use assemblies that bend and disengage with tubing, leaving it loose and vulnerable to vibration. The tightening of bolts on each end of the clamp causes the support material to pull down at the bolting points, resulting in the support midsection bending upward. Plastic or metal spacers exist to maintain spacing between the tubing, but they do not offer vibration control. With the Versa-Clamp®, the tubing is held firmly in place by 3 or 4 points of contact, preventing the tubing from shifting horizontally or vertically. The tubing is seated in dimensionally sided grooves that position each tube within the assembly, so that contact is maintained between the tubing and the support.
Space constraints are commonly encountered as designs are are calling for tighter spaces and reduced skid sizes. Industry standard support assemblies use 1/8″ spacing between the tubing. The Versa-Clamp® can be custom made to space the tubing to suit any application. The Versa-Clamp® also offers the ability to contain multiple sizes of tubing in one clamp assembly, to be stacked, or to be assembled in multiple rows or columns.
The Versa-Clamp has been accepted and specified for many projects and installations on equipment by various major oil and gas companies, engineering and consulting firms, I&E contractors, and subsea systems and controls companies. Below is a list of common applications for the Versa-Clamp®:
- Compressor Skids
- Chemical Injection Units
- Hydraulic Power Units
- Pump Skids
- Methanol Tubing Replacements
- Tieback Installations
- Topside Umbilical Termination Assemblies
- Well Hookups
- AS/SI Tubing Replacements
- Retrofitting Platform Tubing Supports
