WP316L steel with optimal welding and working characteristics
WP316L is part of the austenitic stainless steel family, and it is one of those contemplated by the ASTM A403 standard for the production of connections, even if only a part of this standard is related to material such as WP316L. It also relates to semi-finished products such as plates, bars, [...]

Globe valves take their name from their shape, even though today they are no longer round 30/12/2016
Globe valves take their name from their shape, even though today they are no longer round
We deal in particular with two types of globe valve, Y pattern and T pattern, which differ according to how they are configured internally. The Y pattern valve is used  when fluid does not have to be deviated much, and the plug is sloped at an acute angle in relation to the flow. The Intertubi [...]

WP304L is a family of steel with a low carbon content
The symbol WP304L can indicate austenitic stainless steel, often used in the food industry, excluding some exceptions for example white wine or specific types of fruit juice. It can also be used in the civil sphere, but cautiously in environments where chlorides may be present, for example sea [...]
