Who is ZAIN Industrial?

ZAIN Industrial is a leading expert in industrial mixing solutions. We specialize in providing consulting services, Mixing tanks and reactors as well as Field Services.

What does glass lining inspection involve?

We perform visual inspections to identify cracks or chips, spark (holiday) testing to detect micro-defects, and thickness measurements to check for wear or erosion. We compile all results in a maintenance log for long-term tracking and compliance.

How often should inspections be conducted?

We recommend annual inspections as part of your preventive maintenance program. Some high-use or corrosive-process systems may require check-ins every 6 months to avoid unexpected failures.

What repair methods do you offer?

Minor defects can often be fixed with on-site patch plugs, sleeves, or PTFE repairs. For severe wear or damage, we offer full reglassing services that restore vessels to like-new quality while often reducing cost compared to full replacement.

Can seals and agitator components be checked during inspection?

Yes. Our inspections cover agitator shafts, drive seals, baffles, nozzle connections, and gaskets. We'll identify worn or corroded elements and recommend replacements or adjustments to avoid further liner damage .

Is your inspection service compliant with safety regulations?

All services comply with OSHA confined-space entry, lockout/tagout, and process safety protocols. We document every step to support regulatory requirements such as FDA or cGMP audits.

What is the timeline for inspection and repair?

Standard on-site inspections with minor on-site repairs can be completed within a day or two. If reglassing is needed, total turnaround is typically several weeks, significantly faster than sourcing new equipment .

Can a vessel be refurbished rather than replaced?

Yes—if the steel substrate is in sound condition, reglassing is often the most cost-effective solution. It restores full functionality at around 60‑70% of the cost of new equipment and preserves existing infrastructure .

When is a reactor not a candidate for repair?

If the steel shell has advanced corrosion, structural damage, or if capacity needs changes, replacement may be preferable. Our inspection report includes a technical recommendation to guide decision-making.

There are different methods utilized for selecting and sizing agitators.

The SV, superficial velocity, method.
Power per unit volume and torque per unit volume.

Most of this data is compiled from laboratory testing and experience.

If your corporation has been using mixing equipment for many years and has been through a few upgrades and changes to your mixing equipment, you will have gained some of your own in-house expertise as well. At ZAIN, we can assist you to classify and categorize your mixing equipment.

Mixing impellers are characterized by Flow (pumping number) and Energy dissipation (power number).
