Kashagan hipps surface valves

Surface Valves

We are a high reliability provider of surface valves for petrochemical, onshore, offshore and midstream applications and have designed, manufactured and maintained valves for these critical markets for over 50 years. 50,000 of our valves are installed and are operating across the globe, some still reliably in service after 35 years. We are a trusted provider delivering the right solution to meet our customers’ applications; from large volume, daily service, carbon steel ball valves to one off, high integrity HIPPS solutions, we’re your single point of contact.

Surface Split Gate Valves - onshore and offshore valves

Stringent Design standards All valve design, like any critical component, must meet stringent industry
standards including API 6A, API 6D and API 17D (ISO 10423, ISO 13628, ISO 14723). Designs for production
environments are safety critical and must deliver operational reliability, often at high pressures. Combine this with variability in pressures and temperatures, process fluid/gas composition and bore sizes across
applications, and very quickly you can see that onshore and offshore valve design takes significant
engineering expertise.

Usan Test Tree - Onshore and Offshore valves

The right product to suit the application. Valve design and manufacture varies significantly across petrochemical, onshore and offshore applications. To help our customers start with the right specification we offer a comprehensive portfolio of standard and reliable isolation solutions. Delivering the same robust, inherently safe design, our standard specifications have customisable options to suit these varied service conditions. And because we’re the experts, we guide you through this selection process – if and when needed. What-ever your application; offshore production systems; processing and compression; isolation; storage; recovery; metering or export.

What needs to be considered. The right choice of valve is crucial, whether it be trunnion mounted or floating ball valve, through conduit slab gate or double expanding gate valve each has their benefits and this depends very much on operational performance, duty and service conditions. At this crucial selection stage we must consider operational requirements and ideally this is done with an early engagement partnership with our customer. Operational specifications are clearly affected by multiple aspects such as height, weight or footprint restrictions, bi-directional sealing, high or low temperatures, sandy or dirty conditions, pigging requirements, end connections, installation restrictions, operational duty, and many more – including of course the commercial aspects of cost and availability.
