HDPE Pipe Joining Welding
TETCON is a company that specializes in the supply and Installation of HDPE pipes, fittings, and pipe joining welding. Our customers choose us because we are trained in all forms of heat fusion techniques & work in all types of field conditions.
Many companies claim to be industry leaders and will provide aggressive pricing to win your business, however when their HDPE pipe joining welding installation fails and your project is suddenly at risk (and costs are increasing due to downtime) companies, without fail, call on TETCON to fix the problem. We provide experienced, reliable, professional, and safe field installation services. We believe in doing it right… the first time!
Our professional fusion technicians have been fully trained and certified to operate all thermal fusion equipment (butt, socket, sidewall & electro-fusion), cutting equipment, mobile transfer equipment and are well versed in all aspects of handling polyethylene. They are always up to date on the latest safety procedures and are equipped to work in extreme cold, wet, outside, inside and come prepared for the job.
We offer our customers a full range of products and services providing fusion machines, a technician, pipe & fittings, and all the equipment that goes along with completing a professional fusion job at your job site. Our technicians arrive prepared and equipped to stay on the job until it is done right. With a fleet of polyethylene pipe fusion machines in stock and relationships with fusion machine vendors, we can provide butt-fusion, socket fusion, sidewall fusion or electro-fusion joints. We are well equipped to handle the most demanding fusion needs of our customers and we document every weld.
Butt Fusion
HDPE fusion welding is the process of bonding High Density Polyethylene piping together. By heating a section of each pipe beyond its melting point effectively changing its molecular structure and carefully joining them together using a precise amount of force. This is the actual “fusion”. It’s critical that the force stays in place until the joint cools and the pipes return to their original, durable state. The result is a new standardized pipe that will be equal in strength (if not stronger than) the segments alone. It takes a thorough understanding of this procedure and the equipment used to properly accomplish this process. From manipulating the heat source to the angle and even speed at which the pipes are joined, it’s critical to have properly trained personnel with the right equipment to ensure safety and quality. HDPE is one of the many commercial plumbing services we offer at Tetcon.
Electro Fusion
Electrofusion is a simple method of joining PE pipes in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. Prefabricated fittings are used, incorporating an electrical heating coil which melts the plastic of both the fitting and the pipe, causing them to fuse together. The characteristics of the fitting to be welded, such as the fusion time, are registered via a barcode on the fitting. An electrofusion control unit (ECU) supplies the electrical energy necessary to heat the coil. When the coil is energised, the material adjacent to it melts and forms an expanding pool which comes into contact with the surface of the pipe. The continued introduction of heat energy causes the pipe surface to melt and a mixing of pipe melt and fitting melt takes place; this is vital to produce a good weld. Following the termination of the heat cycle, the fitting and the pipe are left to cool and the melted material solidifies to form a sound joint.
Pressure Testing
TETCON provides hydro-static pressure testing and certification for its extensive range of piping systems to prove the integrity of the welded joints. The test ensures the installed piping system is capable of withstanding the design pressure and the fitness of the system.
