Introduction

When dealing with more advanced piping projects, there might come a time where more sophisticated processes are applied. Some of the piping materials have to be welded and joined together and one of the ways to achieve this is by electrofusion. This method is used to join various types of pipes such as MDPE, HDPE as well as other types of plastic grade material pipes. For those who are new to electrofusion, this process uses a special fitting that have a specialised built-in electric heating components used to join pipes together.Overall, it is perhaps one of the most idealistic ways to join two ends of a pipe together in a simple, fast, cheap, and reliable way.

Gas fittings & jointing

How this process works is relatively simple as the pipes are cleaned thoroughly first before they are joined. They are then placed into the electrofusion fitting with a clamp and an electrical voltage of around 40V is used for a short time. The coils inside the fitting will heat up and melt the inside of the fitting and the outside of the pipe wall which then creates the welding process. The pipe is then left to cool which creates a very strong and uniformed joint. It is basically a heating process which melts plastic and wields it together again to form one uniformly strong and perfect joint.

When applying electrofusion gas fittings, it is imperative that the ability of the individual who is applying this method is skilled enough. The person needs to have prior training as this type of welding process needs to be done correctly especially if it is later to be used for applications such as gas. As with many installations, there are probable risks that can and will occur if safety precautions are not taken beforehand. Leaks may occur in the electrofusion gas fittings and can prove catastrophic.However by using robust quality tools and utilities, this factor can be safely eliminated. Those without proper training should not at all attempt to install electrofusion gas fittings without prior practice, especially if the utilisation during that point in time is permanent.

Applications

A lot of industries that deal with water and wastewater treatment will most likely use PE pipes and electrofusion gas fittings as a means to weld the pipes together. The utilisation of water, gas and sewage pipes are ideal for electrofusion use. A company who might be in the gas industry might prefer to use this application as a quick and flexible way to install or repair old and damaged parts. In addition, the simplicity of this method enables companies to save a lot of money in maintenance and installation costs. This then further enables companies to rely solely on PE formed pipes over the metal graded materials which are heavy and more expensive to maintain.

The important thing about using this method is that the process has to be carried out correctly. This means that the pipe surfaces and electrofusion fitting has to be cleaned thoroughly before use. In addition, the pipes have to be aligned correctly (straight) and the human welder has to have the experience in operating the fitting tool which all greatly impacts towards the risk of leaking. If installed correctly by competent hands, the fittings can last for up to a minimum 50 years.

Conclusion

Without a doubt, there are many great advantages that can be had by utilising electrofusion. A strong and uniformed joint can be achieved and can last a very long time. However, achieving this result requires the skilful operation of a handler as well as using the quality equipment for it. If done right, this practical method of welding pipes will be beneficial in terms of cost effectiveness, as well as time saving measures when it comes to its application. This method is an ideal and practical solution for those who are in the water and gas industry, or those who utilise these elements.

robots-construction

The future of construction sites is changing thanks to a dizzying array of new technologies. Coming soon to a job site near you could be construction robots, drones and pre-assembled materials manufactured via 3D printing. This is no longer technology in the making, it is here and ready to be applied.

Interested in how this technology will affect the construction business as you know it? Here is an overview of some of the potential impacts of drones, robots and 3D printing technology on the construction industry in the coming years.

Drones for Surveying and Inspections

According to Construction Business, drones allow builders and investors to record progress on a job site quickly and accurately. Drones make site analysis less complicated and time consuming.

A camera is attached to the drone, which can fly and hover over a construction site, capturing aerial photos. This seemingly basic functionality is extremely beneficial with jobsites located in areas that are dangerous or difficult to reach.

One spot where drones have been utilized for inspections are on dams, where they are used to check for leaks, cracks ad deterioration. Drones can be used to map changes at regular intervals in troublesome areas, making it far easier for engineers to pinpoint worsening conditions.

Robots Clocking In

One of the most advanced robots designed for construction applications, developed by a group of Swiss researchers, has demonstrated an ability to independently lay bricks in custom designs, adapting the work to local conditions.

This pioneering construction robot uses an articulated arm and caterpillar tracks, guided by two computers. The first computer gives instructions to the arm and the second navigates it around the site. Both computers make use of a laser guidance system that is able to create a 3D map in of the terrain.

Scientists foresee a range of future applications for construction robots. Rather than replacing human workers, the visions is that the robots will work together with humans on the job site, each bringing a set of skills that complements the other.

Combining the Capabilities of Robots, Drones and 3D Printing

Experts in construction are working to use combination of several different emerging technologies for greater efficiency, automation and speed. One example is an aerial 3D-printing drone featured at the SXSW Robot Petting Zoo that extrudes concrete. It comes equipped with six rotors, a laser finder and GPS sensors, all hooked up to a spiral material conveyor. Theoretically, this type of 3D printing drone could eliminate the need for scaffolding on a project.

Robots are also collaborating with 3D printers at the California College of the Arts, in the form of Swarmscapers. These robots, which are also 3D printers, were tested by having them extrude glue that bound together layers of sawdust, creating a high-tech version of termite mounds. The idea is that they can make use of native materials on any site, an ongoing ambition of NASA.

On future construction sites, architects as might function as master programmers instead of simply as designers.
