Profile: Ray Oil Tool Co., Ltd. specializes in centralization services. Our products include centralizers, centralized float equipment, and special products. The innovative design of the centralizer blades reduces balling between the blades, resulting in complete utilization of the spiral centralizer in swirling the cement. Our spiral blades are precisely contoured to the curvature of the body to allow maximum blade contact with the wellbore. The width of the blades is designed to give the best wellbore support without knifing into the wellbore side, and still have good fluid passage.
