APS Rotary pulser system shroud and steel casing for MWD/LWD
Description
The Shrouds /steel casing is made of steel material. The inner hole of the Shroud is coated with tungsten carbide to extend its service life. The 3 1/4-16 UN-2B threaded portion of the Shroud is precision ground using precision CNC machines.
This meticulous manufacturing process ensures the highest accuracy and consistency in threading. With this level of accuracy, you can trust that each Shroud will fit seamlessly into your drilling equipment. Our experienced team can machine difficult to your specific drawing requirements.

Our Advantages
1. 15-5PH is better than 17-4PH material and Same as the original shroud of APS, it has a long service life.
2. Tungsten carbide spray powder is good.
3. Excellent abrasion resistance.
4. High fractural strength.
5. High thermal conductivity.
6. Small heat expansion co-efficient.
