stainless steel tube

Welded vs press-fit stainless steel tube: what is more cost-effective?

We often get asked if either welded stainless-steel tube or press-fit stainless-steel tube is more cost-effective, but the answer isn’t as simple as some may think. Both pipe joining methods have different cost factors which can increase or decrease the cost of a pipeline project depending on a range of factors and, simply put, some applications favour one over the other. In any piping project, the ultimate aim is to ensure it’s cost-effective, time-efficient, and long-lasting which is why we thought we’d explain the different cost factors for each system type so you can ascertain which is the best fit for your next project and unique requirements.

Carbon steel press-fit pipe

What are suitable applications for press-fit carbon steel?

Steel is an incredibly versatile and useful material for piping solutions in a variety of applications. Steel’s properties including its strength, rigidity and relatively low cost make it a very popular choice for piping solutions across the globe. But not all steel is the same. Each different type of steel has its own unique characteristics, advantages, and applications. Carbon steel is just one type of the broader category of steel and is often preferred over other kinds of steel, but why is this? In this article, we’re going to explain just that. We’ll cover in, a general sense, what exactly carbon steel is and its benefits, then dive down into what key applications carbon steel using the press-fit jointing method is best suited toward. Simply read on to discover some important considerations for carbon steel pipework.

Press-fit vs welded piping

Press-fit VS welded piping: Which should I choose?

For all pipeline trade professionals, connecting pipes efficiently and to a high standard is a vital component of every project. Traditionally, welding has been a reliable and proven jointing method, however, there have been developments such as press-fit solutions that equally have their place in the market. Both press-fit and welded piping installation methods offer various advantages which we will shed some light on in this article. We will also outline the key differences between press-fit and welded piping, key applications, and the pros and cons of either option.

Europress in compressed air systems

Is Europress suitable for compressed air piping?

Across an array of commercial and industrial applications, compressed air systems are an integral service. Compressed air systems can be very complex and intricate so it’s critical to have a full understanding of what piping system will provide you with the best long-term results, both financially and in terms of system operation efficiency and longevity. There are a range of considerations in a compressed air system, from upfront costs, operating and management costs, the efficiency of the system, to the added production value. For these reasons, it’s imperative that you make an informed decision and select the piping solution that will offer the best outcome.

Industrial PVC pipes

PVC pipes explained

As one of the most universal and versatile types of plastic piping to exist, PVC piping is employed in a multitude of different applications globally, specifically across the agricultural, industrial, commercial, and civil markets. In comparison to their metal piping counterparts, PVC pipes are lighter giving easier installation, offer greater chemical resistance, and in particular when compared to mild steel, offer greater corrosion resistance. However, they do have a risk of succumbing to thermal expansion or contraction. So while PVC will be the perfect solution for many applications, metal will suit others, and it’s important you know when one is more suited than the other. PVC pipes are offered in a variety of sizes with numerous fittings available and are safe for use in cold and warm water (operating temperatures of 4-40°C with temperature spikes up to 60°C) applications.

Benefits of Europress

What are the benefits of Europress?

In today’s dynamic world we frequently hear the statement “the only constant thing at the moment is change” and how true this is. More than ever before we are being confronted with change almost on a daily basis whether it be the way we live, our work, the way we travel, the way buy, the way we communicate, the list is endless. As with any change there are those who jump at the opportunity to try something new and embrace it. There are those who hold back without rejecting the change but would rather wait until it has been proven and learn from the positive or negative impacts of change from others. Then of course there are those who just straight out refuse change saying, “if it ain’t broke why fix it.” The unfortunate reality for the latter is in some way, shape, or form we will have to change.

PVC pipe

5 design tips to extend the life of PVC pipework

PVC first began to be manufactured in the 1940’s used for Drain-Waste-Vent piping during the reconstruction of Germany and Japan following World War Two. Having been around for 80 years PVC has proven itself to be a reliable piping system. As with any piping system, understanding the limitations of the selected piping material and following key design principles can significantly improve the life expectancy of a piping system.

Pipe bracketing NZ

The Importance of Getting Your Pipe Bracketing Right

Bracketing plays an important role in giving you the maximum or even extending the expected life of your pipework. There can be many and varied causes for pipe failure, but one common cause is poor selection and installation of bracketing. Issues such as using brackets of dissimilar metals or placing a bracket too close to a change in direction are common factors which can lead to failure. The following quick guide will give you an insight into correct bracket support, selection, placement, and anchoring.
