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 (FAQ)
What are WA Series Safety Clamps primarily used for?
WA Series Safety Clamps are designed for handling flush joint pipes and drill collars. They provide a secure grip to prevent accidental tubular drops during the make-up or break-out processes of drilling equipment.
How do MP Safety Clamps accommodate different pipe sizes?
MP Safety Clamps feature an adjustable design. By simply adding or removing chain links, the clamps can be perfectly sized to handle drill collars and flush joint pipes of varying outer diameters.
Are these safety clamps compliant with industry standards?
Yes, all of our safety clamps undergo rigorous proof-load testing and dimensional verification to ensure full compliance with the API Spec 7K standard.
What materials are used to manufacture these safety clamps?
The clamps are manufactured from high-strength alloy steel. They also undergo controlled heat treatment processes to achieve optimal toughness and long-lasting wear resistance in harsh drilling environments.
How does the multi-link chain structure protect the tubulars?
The multi-link chain structure ensures that the radial load is distributed evenly around the pipe. This significantly reduces stress concentration, thereby preventing surface damage or crushing of the tubulars.
What is the maximum pipe O.D. that the MP-XL clamp can handle?
The MP-XL safety clamp, when equipped with 33 chain links, can accommodate a maximum pipe outer diameter of up to 36-1/8 inches.
