Product Description

Product Description

•API standard oilfield stabilizers are manufactured from one solid bar of AISI 4145H modifed steel, usually have 3 blade or 4 blades.Professional heat-treatment process gurantees the mechanical strengths meet the requirments of API SPEC7-1. Hardness of 285-341HB can be assured with 1'' beneath the outer surface and 4 quadrant across the neck OD.

•Replaceable sleeve stabilizer consists of mandrel and sleeve. The function is the same as spiral integral blade stabilizer. It can suit to different hole sizes and increase working life by changing the different size sleeves. The sleeve is threaded on the mandrel, so the sleeve can be fasten to the mandrel tightly and changed easily.

Drilling Stabilizers is an important tool to control hole deviation in petroleum and gas exploration drilling process.The type of it can be divided into drill string type and near bit type. The main types of stabilizers are divided into Integral Spiral Blade Stabilizer, Integral Straight Blade Stabilizer, Replaceable Sleeve Stabilizer, Tapered Stabilizer, Float Valve Stabilizer, Non-Rotating Stabilizer.

Q What is the difference between bi-metal, ceramic, chrome-plated, and high-frequency quenching cylinder liners?

A
| Type | Inner Material | Hardness | Service Life | Best For |
| Bi-Metal | High-chromium cast iron | HRC 62 | 800h+ | General high-pressure, abrasive drilling |
| Ceramic | Al₂O₃ or Zirconia | HRC 80+ | 1500h+ | Extreme abrasion, high-sand formations |
| Chrome-Plated | Hard chrome coating | HRC 55 | 300-400h | Moderate conditions, budget operations |
| High-Frequency Quenching | Quenched alloy iron | HRC 50 | 200-300h | Light-duty, low-cost applications |
