Oil & Gas Transmission
Oil and gas transmission lines use three main ON/OFF valve service products:
- Ball valves, full or reduced bore, Side or Top entry, bolted or welded body.
- Through conduit gate valves (slab or expanding gate).
- Full opening swing check valves.
The main standard of reference for all these valves is API 6D / ISO 14313.
Subsea transmission lines foresee a wide use of Ball Valves that have to resist to hyperbaric outside pressure environment (standard API 6DSS / ISO 14723) FLUITEK ORSENIGO VALVES, facing this application is continuously upgrading its testing equipment to submit its products to various subsea installation conditions.
Gate, ball and check valves are designed to meet the so called “piggable” requirement. The use of equipment launched in pipelines to clean the line (“pigs”) or measure the integrity of the wall thickness of the line (“smart pigs”) has become a standard in the industry.
According to API 6D. Through conduit gate size 2” – 48”, Classes 150#, 300#, 600#, 900#, 1500# as applicable. Class 2500# available on request for smaller sizes. Side entry ball valves size 2” – 36”, Classes 150#, 300#, 600#, 900#, 1500# as applicable. Class 2500# available on request for smaller sizes. Full opening swing check valves size 2”- 48”, Classes 150#, 300#, 600#, 900#, 1500# as applicable. Ball valves fire test design to API 607/API 6FA/BS 6755. Secondary sealing available. Materials availability: carbon steel, low temperature carbon steel, alloy and stainless steel, duplex steel, nickel alloys. CE/PED requirements compliance available.
Single and double expanding gate valves are available on request. Stem extensions for valve underground installation are available per customer requirements. Double block and bleed dual compact ball valves allocated in a single side entry body to ensure positive shut off with leaking detection device. Fully Welded ball valves.
