    Ball valves  have increased in popularity over the last few years, offering excellent solutions to many diverse applications. Ball valves offer ease of use in both the fitting and its maintenance. It is a preferred option, adopted by many Engineers. A ball valve is classed as a quarter-turn shut-off or isolation valve that controls the flow of a liquid or gas by way of a spherical ball with a hole bored through the centre and held into the valve body by two identical seat seals.   Once fitted the valve is turned 90°, the valve opens or closes. When the valve is open the ball's, hole is in line with the flow direction and closes when it is turned 90°by either a manual handle or by actuation. When the valve is open the lever handle should align with the pipe or flow and is perpendicular to the pipe when it is closed. This makes it easy to determine the position status of the valve.   Ball valves usually have a long operating life before maintenance is required (around 50,000 oper

  Did you know that   vacuum bags   are the most important factor in quality food storage? If you find that your vacuum bags are melting when you use a vacuum sealer to evacuate them or that the machine is not removing enough air, then the problem is with the vacuum bags you are using, not with the machine as most users believe. Read the following post for the most important tips when vacuum packing food for freezing and long term storage.   What are the best vacuum bags for food? There are three important factors that determine the quality of a vacuum bag. The material Thickness of the layer Ribbing profile The material The construction of the vacuum bag is very important as the inside of the bag is in direct contact with the food. The bag manufacturer needs to guarantee that all materials used are food grade and list the temperatures at which the vacuum bags can be safely used (whether the bags are suitable for freezing and cooking by the vacuum low temperature cooking method).   Foo

  Car maintenance is essential to keep your vehicle running in top condition. And, this maintenance sometimes requires you to remove and replace faulty or old car parts.   In addition to regular inspections, replacing car parts is actually more common than most people think. These replacements are essential and are clearly listed in the owner's manual.   Here are some  car parts  that need to be inspected and replaced more often than others.   1. Brake pads This is one of the components of your car's braking system that requires regular maintenance. Brake pads are no exception. If you notice that they are not as thick as they should be, it may be time to replace them. Check them by looking at the wear points between the spokes of your wheels. If they're thinner than a quarter inch, it's time to get new ones. Brake pads wear out much faster than you think, and you need to replace them as soon as possible.   You may hear a squealing sound from your car's wheels when y

Exothermic welding   is a chemical process which enables the molecular bonding of metals in a long-lasting way. It is applied to metal joints and its use is very widespread in sector such as rail and the electrical sector, in the grounding connections.   Exothermic welding achieves molecular bonding between conductors made of copper, stainless steel, galvanised, bronze, etc. The basis of the process is an exothermic chemical reaction in which the aluminium reduces the copper oxide producing the copper that totally or partially melts the conductors to be welded, providing a superior connection to any mechanical joint (more susceptible to wear and corrosion), with respect to both mechanical and electrical properties.   In this article, we will develop the evolution of exothermic welding since its invention in 1893 to the current innovations, which have meant important improvements in the process.   Thermite Welding Powder   Exothermic welding: from invention to innovation   The  exotherm
