Valves, Fittings & Manifolds

Spina Group offers a wide range of measuring instruments. The company manufactures and supplies instrumentation valves and manifold, pots and siphons, fittings and adapters and industrial tubings.

The processes of chemical and petrochemical plants both onshore and offshore require the regulation of the values of physical and / or chemical parameters in order to maintain a correct efficiency of the plants themselves. Furthermore, the demands on instrumentation systems designed for offshore applications continue to grow.

Since the oil and gas sector seeks to exploit ever deeper and less accessible reservoirs, instrumentation systems must be able to operate at significantly higher pressures, particularly in subsea equipment used for projects with long life cycles. A wide range of accessories is available too.

Our Offer

Manifolds and Valves

Spina Group offers different types of pressure measuring instruments, including manifolds and valves suitable for static pressures, applications with liquids or for differential pressures, available for different types of installation and with different styles and designed to provide a safe and reliable method of measurement pressure and versatile towards installation within the process.

Compression Fittings

Spina Group offers a wide range of fittings, caps and reductions which ensure the absence of leaks (even in the presence of gas), good resistance to high tightening, easy assembly with the possibility of repeated assembly and disassembly.

Pots and Siphons

Spina Group offers a wide range of condensate separation barrels, air distribution and siphons, which are used for the treatment and distribution of the process fluid before it reaches the instrument.

The siphons are used on the steam measurement lines to prevent it from directly investing the instrument and also to guarantee good heat dissipation avoiding overheating of the pressure gauge.

Tubing

Spina Group offers various types of cable holders for explosion-proof electrical systems and UL type and flexible pipes necessary for the construction of suitable “electrical conduits” inside walls and floors so that the electrical cables are protected from impact, humidity and compressions.

Latest successful projects

Bioenergy

Sannazzaro Revamping

The Sannazzaro Revamping is a project for the partial conversion of Eni’s Sannazzaro de’ Burgondi refinery, in the province of Pavia. Developed by Eni, the project involves the conversion of the Hydrocracker HDC2 unit, the construction of a pretreatment plant for waste and residues, and the upgrade of logistics and auxiliary infrastructure. The new biorefinery will have a capacity of approximately 550,000 tonnes/year and will produce HVO diesel and SAF-biojet, contributing to the decarbonization of transport and to the expansion of Eni’s biorefining capacity.

Oil&Gas

Luanda Refinery

The expansion and modernization initiative aims to significantly increase the refinery’s petrol production capacity, quadrupling it to 450 thousand tonnes per year. As a part of this project, the Combined Cycle has been revamped to utilize hydrogen generated by the new Platforming unit. Additionally, energy production has been optimized by recycling gas, resulting in a notable reduction in polluting emissions.

Petrochemical

Beaumont 3000 MTPD Synloop Ammonia Plant

The Beaumont New Ammonia Project, located in Beaumont, Texas, USA, is a major lower-carbon ammonia facility with a production capacity of 3,000 metric tonnes per day (1.1 million tonnes per year). Owned and operated by Woodside, the project is designed to expand the supply of lower-carbon ammonia for applications including power generation, marine fuels, and industrial feedstock. A key milestone was achieved in December 2025 with the successful production of first ammonia during commissioning.
