The safety valves are components that are able to increase the safety level of a thermo-hydraulic system to prevent that there is an extremely dangerous pressure in the system. In Italy and in Europe the use and installation are defined by the "pressure equipment directive" which specifies that it [...]

Installation of flexible water hoses Flexible hoses are components that have numerous applications and can involve very different fluids and materials. Although the correct mounting instructions are always provided, many failures and malfunctions derive precisely from an incorrect [...]

What is brass? Brass is a metal alloy whose main components are Copper (Cu) and Zinc (Zn). Inside the family it is possible to distinguish binary brasses, composed only of copper and zinc, and ternary brasses, which have another alloy element besides the two main ones. The percentage of zinc [...]

What is oxyacetylene welding? Oxyacetylene welding represents the welding technique in which the energy is produced by combustion in equal parts of acetylene and oxygen. This methodology, discovered in 1895, was the most used during the first decades of the twentieth century, before being [...]

A range of articles that has an added value, even if not well known, is that of balanced pressure regulators suitable for large flow rates for use in high, medium or low pressure systems. Their use is particularly useful in civil and industrial environments to reduce the pressure of methane gas [...]

In the construction of the gas taps, the locking system used most frequently is the pin system or in some cases with a conical seal. This is because the safety of the tapered metal-on-metal seal is still the best available. The opening and closing control is entrusted to a micrometric screw [...]

The connection of several tanks to a system can be carried out by means of a control unit or a mini-control unit. Both have from 2 to 4 leads and are equipped on each derivation with a shut-off valve. This valve allows to replace one of the empty tanks without stopping the flow of gas to the [...]

The production of technical articles for gas requires the use of selected and certified materials coming from trusted supply chains. The brass used comes from leading Italian companies specialized in the production of bars and semi-finished products. This combined with cutting-edge processing [...]

When we talk about safety valves we must distinguish between two large families, the one destined to the safety of gas burners and the one for the prevention of overpressure in the systems in which they are present or a boiler or an electric boiler. These are products that have been developed [...]

In the plumbing and heating systems the brass fittings are one of the primary elements together with the tube that can be metallic, and in this case it is screwed directly to the fitting or composite, such as multilayer. And then there is the need to use special brass fittings with an ogive that [...]
