What Types of Plastic are Used in Water Storage Tanks?

The most common types of plastics used in water storage tanks are polyethene and polypropylene. These materials are known for their durability, resistance to chemicals, and suitability for storing potable water. High-density polyethene (HDPE) tanks, in particular, are popular for their strength and UV resistance, making them suitable for outdoor use.

Are Plastic Water Tanks Safe for Drinking Water?

Yes, plastic water tanks made from food-grade materials like HDPE or polypropylene are safe for storing drinking water. These tanks are designed to meet strict quality standards and regulations to ensure that the water remains clean and uncontaminated. Always check for certifications or compliance with local health and safety guidelines when purchasing a water storage tank. Hence, it is better to buy certified water tanks.

How Long Do Plastic Water Storage Tanks Last?

The lifespan of a plastic water storage tank depends on various factors, including the quality of the material, UV exposure, and maintenance. High-quality plastic tanks can last for decades, especially if they are installed and maintained properly. Regular inspections and cleaning can extend the tank’s lifespan and ensure the water’s quality.

What is Electrofusion?

Electrofusion is a way to join two plastic pipes together with a permanent bond. The pipes to be joined are cleaned. They're then fitted into a special electrofusion machine and electrically heated until the two pipes - and the fitting around them - melt and fuse. The welding process differs slightly depending on what kind of pipes you're joining together, but the core process remains the same overall.

Should You Choose Electrofusion or Butt Welding?

The type of joining you choose should be situational. The project's size, location, and overall type will factor into your decision. When deciding between these two welding strategies, consider the following:

Does the job require precise piping meant for tighter spaces? Electrofusion is often better for these jobs.

How large is the pipe you need to install? Electrofusion will only work on lines from 20mm in diameter to 710mm in diameter. Butt welding will work on pipes up to 2000mm in diameter.

What's the experience level of your contractors? Electrofusion is a complicated process, but it's easier to automate. Effective butt welding often requires more experience than electrofusion welding.

What are the causes of electrofusion joint failures?

The electrofusion procedure should be done by a skilled person. There are so many reasons for joint failure like Improper scraping of the pipes, improper holding & alignment of pipe, machine calibration – fusion machine gives lesser voltage, excessive scraping of pipe- too much loose pipe.
