Safety Clamp Features
High strength alloy steel with controlled heat treatment for optimal toughness and wear resistance.
Multi-link chain structure distributes radial load evenly, reducing stress concentration and surface damage on tubulars.
All clamps undergo proof-load testing and dimensional verification to ensure API Spec 7K compliance.
Adjustable configurations accommodate a wide operational range without sacrificing grip security.
Frequently Asked Questions
What are WA Safety Clamps primarily used for?
WA Safety Clamps are primarily used for handling flush joint pipes and drill collars. They are designed to prevent accidental tubular drops during the make-up or break-out processes of drilling equipment.
How do MP Safety Clamps differ from standard models?
MP Safety Clamps are highly adjustable by simply adding or removing chain links. This makes them ideal for handling drill collars and flush joint pipes of varying diameters with maximum flexibility.
What materials are used to manufacture these safety clamps?
These safety clamps are manufactured using high-strength alloy steel. They undergo controlled heat treatment to ensure optimal toughness and excellent wear resistance in demanding environments.
How does the multi-link chain structure protect tubulars?
The multi-link chain structure distributes the radial load evenly across the pipe. This significantly reduces stress concentration and prevents surface damage or scoring on the tubulars.
Do the safety clamps meet industry standards?
Yes, all safety clamps undergo rigorous proof-load testing and strict dimensional verification to ensure full compliance with API Spec 7K standards.
Can one clamp handle multiple pipe sizes?
Yes, thanks to their adjustable configurations (such as altering the number of chain links), these clamps can accommodate a wide operational range of pipe sizes without sacrificing grip security.
