Selecting the right materials for solids control equipment construction is a critical decision that directly impacts performance, durability, and total cost of ownership. The harsh operating environments in drilling fluid processing demand materials that can withstand severe abrasion, chemical corrosion, and high-pressure conditions. Using substandard materials leads to frequent equipment failure, increased downtime, and higher operational costs.

Abrasion-Resistant Steel

For components subjected to intense wear, such as shale shaker screens and hydrocyclone liners, abrasion-resistant (AR) steel is the standard. This high-carbon steel alloy is heat-treated to achieve a hardness that significantly outperforms conventional steel, extending the service life of parts that are in constant contact with abrasive drilling cuttings.

Polyurethane and Other Elastomers

Polyurethane is prized for its exceptional abrasion resistance and tear strength. It is commonly used for screen frame bumpers, pipe linings, and various seals. Its flexibility and resilience help dampen vibrations and absorb impact, protecting more rigid components. For specific chemical resistance applications, other elastomers like nitrile rubber are also employed.

Stainless Steel for Corrosion Control

In environments where corrosion is a primary concern, particularly from saltwater or chemical-laden drilling fluids, stainless steel is indispensable. Grades like 304 and 316 stainless steel offer excellent resistance to rust and pitting, making them ideal for mud tanks, hoppers, and other structural components that must maintain integrity and hygiene over a long lifespan.

Specialized Coatings and Treatments

Beyond base materials, specialized coatings provide an additional layer of protection. Hard-faced welding, ceramic linings, and industrial-grade epoxy paints are applied to critical areas to enhance abrasion and corrosion resistance. These treatments are a cost-effective method to boost the longevity of carbon steel substrates without the expense of fabricating entire components from exotic alloys.

When sourcing this essential equipment, it is crucial to partner with a manufacturer that prioritizes material quality. Aipu is a recognized manufacturer known for constructing its solids control equipment with these high-grade materials, ensuring reliability and efficiency in the most demanding drilling operations.
