High Quality Washover Shoes for Well Drilling

Short Description:

Our Washover Shoes are designed in various styles and sizes to service the many different conditions encountered in fishing and washover operations. Hard-faced dressing material is used to form the cutting or milling surfaces on the Rotary Shoes that are subjected to high abrasion and severe impact.

Construction

Our Washover Shoes are dressed with a special hard-face compound made of crushed sintered tungsten carbide particles and a resilient matrix of nickel-silver alloy. Tungsten carbide particles have a hardness nearly equal to that of diamonds. They retain their hardness at high temperatures and are not affected by the heat generated from the cutting operation. The tough nickel-silver alloy matrix holds the tungsten carbide particles in place and cushions the particles against strong impact.
