High-Pressure Shell and tube heat exchangers for oil processing and much more.

Our Engineering Department is capable of performing Mechanical Design and Thermal Design using the most qualified Software Programs (HTRI or HTFS) in compliance with all International Codes of practice, as ASME BPVC Section VIII Div.1 and Div.2, ASME BPVC Section I, BS PD 5500, AD 2000 MERKBLATT, etc. and in accordance with all International Standards, as TEMA, API, ANSI, DIN, UNI EN, etc.

We purchase semi-finished products such as plates, forgings and tubes only from selected and qualified Sub-Suppliers.

We use cutting and rolling machines to prepare plates for subsequent manufacturing sequences, while Computerized Machining Centres are operated to turn forgings and drill tubesheets.

The entire production cycle is performed in our own premises by our highly experienced personnel.

Villa & Bonaldi’s welding equipment, procedures and staff are extensively qualified and skilled to handle all normally-treated materials, such as carbon steel, killed carbon steel for low temperatures, low-alloy steel, medium-alloy steel, austenitic and ferritic and duplex stainless steel, cladded steel, copper alloys, nickel alloys and titanium.

Villa & Bonaldi has the most advanced equipment for manual and automatic welding, as well as for pre-heating and post-heating operations.

We have developed and perfected the ability of making faultless weld deposits starting from wire under gas and strip under flux.

The construction of tube bundles is closely examined and surveyed at each step. Tubesheets and baffles are always in compliance with strictly defined and stringently controlled tolerances.

“U” hairpins are produced in a special workshop equipped with a tube bending system capable of complying with standards even for small radii. Tubes are fixed to tubesheets by means of two methods: expanding and/or welding. In expanding, the force is controlled electronically and the calibration continuously monitored. Welding, instead, is performed either manually or by computerized guns.
