Product Description

Product Description

Non Magnetic Drill Collar

ShunFu offers special nonmagnetic collars for MWD, LWD and FEWD applications, which are manufactured to the customers specification and design. These collars are used extensively for directional drilling, drilling horizontal wells and formation evaluation. Our modern facilities allow us to produce even the most difficult tools according to our customers specifications.

These collars are used extensively for directional and horizontal drilling as well as formation evaluation while drilling. Our modern facilities allow us to produce even the most complex tools according to our customers specifications.

Our high strength grade steel alloys P530, P550, P580 and P750 are used for these very sophisticated parts because of their proven mechanical properties and corrosion resistance. The standard P530 material has been enhanced with our P550 and P580 material. P550 and P580 have a higher chromium and nitrogen content which provides better resistance to pitting corrosion in addition to better mechanical characteristics and endurance strength. Our new P750 brand offers an extraordinary competitive material to common Ni-based alloys.

One of the main strengths of ShunFu is the ability to be a single source manufacturer of special Non Magnetic collars. Only those products which successfully pass our rigorous inspection controls are allowed to leave our factory. From the sourcing of materials to the final quality control all ShunFu manufactured products pass through our precision machining production steps including BTA boring, CNC lathe and milling, roller burnishing, shot peening, long distance gunhole-drilling and laser cladding at a 6-axis machine.

The reputation of ShunFu in the manufacture and supply of Non Magnetic drill string components is based upon extensive in-house experience both in metallurgy and precision manufacturing. ShunFu has always been the leader in the development of Non Magnetic materials, special manufacturing processes and testing procedures such as hammer peening and hot-spot testing.

Being specifically focused on the manufacturing of nonmagnetic drill string components makes ShunFu a leader in complex precision machining and service at the highest of standards.

As you drill in areas closer to the earth's magnetic poles, it is essential to use a non-magnetic drill collar. Our non-mag drill collars offer strength and hardness while neutralizing magnetic inference. Compatible with standard drill string tools and stabilizers, our non mag drill collars are manufactured to API Spec 7-1. Inventory includes:

1. Slick
2. Flex
3. Spiral
4. Pony

We treat our non-mag material ID with a shot peening operation to compress the inside diameter which prevents stress corrosion while drilling in H2S environments.

1. Resistant to stress corrosion in sour gas environments
2. Compatible with standard drill string tools and stablizers
3. Spiraling available on request

 

Drill Collars are made from

high purity austenitic stainless steel.
Low & High Yield Material available
Advanced chemical composition control system and special forging process guarantee the excellent mechanical properties, corrosion
resistant performance and high fatigue resistance of our Non- Magnetic material.
Shoot Peening on Connections.
