The Rubber Non-magnetic Centralizer
According to the requirements of our customers, specified parts for the MWD system are focused on the research and development. The centralizer was one of them and it was composed of two parts: anti-corrosive, abrasion resistant, non-magnetic alloy body and strong abrasion resistant elastomer coated over the body. The Specified vulcanization process was laid down in order to keep the elastomer layer stick firmly with alloy body under harsh environment with high downhole temperature and high speed drilling mud erosion.

According to max operation tempreture:150ºC, elastomeric formula was designed and its vulcanization process was planed.

The size of Bolts mounted on the centralizer generally is the ISO socket head M6. In response of the requests of our customers, the ANSI 1/4' -20UNC socket head M6-size bolt can be equipped with the centralizer.

The operation conditions of the rubber non-magnetic centralizer
1.Be used in weak-acid or alkaline drilling mud
2.The max operation temperature is: 150ºC
3.Accumulative service life is no less than 300 hrs (The actual service life varies according to the character of drilling mud and other correlative factors).
The metallic body material of centralizer usually is Monel alloy, non-magnetic stainless steel, Ti alloy or BeCu alloy, etc.

The 4-rib centralizer

The operation conditions of the rubber non-magnetic 4-rib centralizer
1.Be used in weak-acid or alkaline drilling mud
2.The max operation temperature is: 150ºC
3.The Accumulative service life is no less than 300 hrs (The actual service life varies according to the character of drilling mud and other correlative factors).
The metallic body material of centralizer usually is Monel alloy, non-magnetic stainless steel, Ti alloy or BeCu alloy, etc.

The centralizer rubber rib
The centralizer rubber rib with different size or shape can be customized according to the requests of the customers. Some rib of this kind of centralizer has a metallic frame and some hasn't.
The operation condition of this kind of centralizer is the same as the centralizer mentioned above.
