Top 10 Questions for Acid Tank Liner Interview

1. What are the different types of acid tank liners available, and what are their advantages and disadvantages?

There are three main types of acid tank liners:

• Rubber Liners: These liners are made of natural or synthetic rubber and are highly resistant to acids and other harsh chemicals. They are also flexible and easy to install.
• Plastic Liners: These liners are made of high-density polyethylene (HDPE) or polypropylene (PP) and are resistant to a wide range of chemicals, including acids, alkalis, and solvents. They are also lightweight and easy to install.
• Fiberglass Liners: These liners are made of a fiberglass-reinforced plastic (FRP) and are resistant to acids, alkalis, and other harsh chemicals. They are also strong and durable, but they can be more expensive and difficult to install than rubber or plastic liners.

2. What are the factors to consider when selecting an acid tank liner?

Factors to consider when selecting an acid tank liner include:

• The type of acid or chemical being stored
• The temperature of the acid or chemical
• The concentration of the acid or chemical
• The size and shape of the tank
• The budget for the project

Other factors that may need to be considered:

• The liner’s resistance to abrasion
• The liner’s resistance to UV radiation
• The liner’s flammability
• The liner’s compatibility with other materials in the system

3. What are the different methods of installing acid tank liners?

The most common methods of installing acid tank liners are:

• Spray-on Liners: These liners are applied using a spray gun, and they are ideal for small tanks or tanks with complex shapes.
• Sheet Liners: These liners are made of pre-fabricated sheets of material, and they are ideal for large tanks or tanks with simple shapes.
• Drop-in Liners: These liners are made of a single piece of material, and they are ideal for small tanks or tanks with complex shapes.

4. What is the expected lifespan of an acid tank liner?

The expected lifespan of an acid tank liner depends on a number of factors, including the type of liner, the type of acid or chemical being stored, the temperature of the acid or chemical, and the concentration of the acid or chemical.

• Rubber liners typically have a lifespan of 10-15 years.
• Plastic liners typically have a lifespan of 15-20 years.
• Fiberglass liners typically have a lifespan of 20-25 years or more.

5. What are the safety precautions that must be taken when working with acid tank liners?

• Wear appropriate personal protective equipment (PPE), including gloves, eye protection, and a respirator.
• Do not smoke or eat in the work area.
• Keep the work area well-ventilated.
• Handle acids and other chemicals according to the manufacturer’s instructions.
• Dispose of waste materials properly.

6. What are the industry standards and regulations that apply to the installation of acid tank liners?

• ASTM D4754 Standard Practice for Installation of Plastic Liners in Underground Storage Tanks
• NFPA 30 Flammable and Combustible Liquids Code
• OSHA 29 CFR 1910.1020 Access to Employee Exposure and Medical Records
• OSHA 29 CFR 1910.1200 Hazard Communication Standard

7. What are the common problems that can occur with acid tank liners?

• Leaks
• Cracks
• Tears
• Blisters
• Delamination

8. How can common problems with acid tank liners be prevented?

• Proper installation
• Regular inspection and maintenance
• Use of high-quality materials
• Following industry standards and regulations

9. What are the benefits of using acid tank liners?

• Protect tanks from corrosion
• Extend the life of tanks
• Reduce the risk of leaks and spills
• Improve safety
• Comply with industry standards and regulations

10. What are the latest trends in acid tank liner technology?

• The use of new materials, such as graphene and carbon fiber
• The development of new installation methods, such as robotic welding
• The use of sensors and other monitoring devices to track the condition of liners

An Acid Tank Liner is a professional responsible for installing, maintaining, and repairing acid-resistant linings in chemical storage tanks, piping, and other chemical processing equipment.
