Operation and assembly of the safety valves
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 [...]

Mini-control units: the UNI-7131 standard
The UNI-7131 regulation, the last revision of which dates back to May 2014, serves to regulate the design and installation of LPG gas systems not connected to the distribution network. In addition to this, it also establishes the basic rules for replacing the cylinders connected to the [...]

Operation and description of the multilayer fittings
Speaking of fittings, it is necessary to distinguish two main categories: • Fittings to tighten (or to screw) • Press fittings (or to clamp) In addition to these, there are a series of modular manifolds that allow you to create differentiated systems that are in step with the times, [...]

Flexible water hoses: everything you need to know
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 [...]

The manifolds: choice and benefits
Why use a manifold? The choice of a manifold inside a system generally allows to obtain a series of important advantages: • Possibility of creating zone systems: it allows the distinction in more independent systems between them. As far as heating manifolds are concerned, this is [...]

Brass fittings: the choice of the alloy
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 [...]

The use of pressure regulators in oxyacetylene welding
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 [...]

The range of tubular heating elements
With which materials the tubular electric resistances are realized Tubular electric resistances are components that play a major role in heating liquids in open water heaters, pressure water heaters, pressurized and free boilers. It is fundamental, for the correct functioning of these [...]

Compensated pressure regulators for gas
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 [...]

Industrial electrical resistors combined with effective thermostats
The production of industrial electrical resistors is a know-how of our company for a long time, and allows us to produce the best materials of Italian production chain. This allows to obtain a product of excellent quality and long life. In fact, the purity of the copper used for the construction [...]
