Process & Manufacturing: How to Be Successful

Hello, welcome to my blog. My name is Nigel. I live in Perth with my two children and a pet dog. At weekends when I am not at work, I like to paint and play the piano. Five days a week, I run a processing and manufacturing plant on the outskirts of town. For many years, while the plant was doing all right, it wasn't the massive success I once dreamed it could be. At a trade conference, I got talking to a consultant who visited my plant and recommended that I make some changes. Since then, my business has really taken off. I decided to start this blog to offer guidance to others.


Comparing Suitable Plastic Materials for Pressure Pipe Systems

If you are planning on installing a new pressure pipe system in your commercial or industrial property, you should consider selecting plastic pipes. While there are numerous materials which are ideal for conveying fluids, plastic has some unique advantages. This choice is normally less expensive compared to alternatives like steel and prestressed concrete. In addition, plastic can be used to handle diverse materials, including water, oil and even corrosive chemicals. If you are interested in obtaining plastic pressure pipes, consider this short comparison of the most suitable options in the market.

PVC Pressure Pipes

Polyvinyl chloride pipes are fabricated using PVC resin. This substance is compounded with stabilisers and lubricants for ideal structural performance and durability. Unlike regular PVC, the pressure pipe material, commonly known as unplasticised PVC, does not contain plasticisers. Plasticisers are added to increase the flexibility and softness of PVC resin. The absence of this component translates into a high strength-to-weight ratio, impact resistance and excellent flow characteristics. In addition, uPVC has high corrosion resistance, making this an ideal choice for agricultural, industrial and general commercial applications.

PE Pressure Pipes

The cost of purchase and installation of polyethylene makes this material a suitable choice for numerous pressure piping operations. The application of this product ranges from irrigation to gas reticulation due to its general strength and stability. Also, PE pressure pipes are more flexible than PVC. This property means that you can install the piping system through trenchless technology. This minimises the cost of excavating the ground and performing repairs. Also, the PE can withstand unstable ground, so it is the right choice for installation in areas where the ground experiences disturbances.

PEX Pressure Pipe

Cross-linked polyethylene is a variant of polyethylene which is manufactured by cross-linking high density polyethylene. This material is more expensive than the basic PE, but its properties are exceptional for different applications. Unlike the above mentioned plastic pipes, PEX pressure piping can withstand relatively high temperatures. It does not develop scale or react with chlorine like metal materials when installed as part of a water conveyance system. Also, PEX is very flexible, which means that installation is easy and minimal connectors are required.

PB Pressure Pipes

Polybutylene has gained popularity in its heating and plumbing applications in commercial and industrial setup. This material is distinguishable because it can resist stress and damage for prolonged periods at high internal temperatures. As a result, this option is favourable for heat-related pressure applications. Like PE and PEX, PB pipes are flexible and easy to install.
