The operation conditions of the non-magntie rubber centralizer:
1、 Can be used in weak-acid or alkaline drilling mud conditions;
2、 The max operation temperature is 150℃.
3、 Accumulative serice life is no less than 300 hur (The actual service life varies according to the character of drilling mud and other correlative factors).
The metallic materials body of centralizer usually is chosen form Monel alloy, non-magnetic stinless steel, Ti alloy or beryllium bronze alloy, etc.
The centralizer is composed of two parts:anti-corrosive, abrasion resistant, non-magnetic alloy body and elastomer with strong abrasion resistance coated over the body. The Specified vulcanization process was laid down in order to keep the elastomer layer sticking firmly with alloy body under harsh environment with high downhole temperature and high speed drilling mud erosion.
