API 7 1 Integral Type P530 Non Magnetic Stabilizer for Directional Drilling

Description

API 7-1 Integral type P530 Non magnetic stabilizer for directional drilling

Tiptop integral type non magnetic stabilizer is made from one solid forging of non magnetic steel. The material is high purity Chromium Manganese Austenitic stainless steel.

Ultrasonic inspection and MPI inspections are performed on each forging over its full length and section, after rough machining according to API Spec 7-1. Mill test certificates including mechanical properties, chemical analysis, magnetic properties and inspections are supplied with all stabilizers.

We have the capacity to produce Non Magnetic Stabilizer up to Crown OD 26", Each of our non magnetic tools is tested according to ASTM A262E practice, in order to make sure there is no intergranular corrosion.
