Aker Solutions wins Heidrun platform equipment frame agreement

Aker Solutions has won a frame agreement from Statoil to supply, refurbish and store compensation equipment used to stabilise and control production risers on the Heidrun platform in the North Sea. The contract value is undisclosed.

Production risers are vertical pipelines between the seabed and a floating production facility. They are used to transport produced hydrocarbons, as well as production materials, such as injection fluids, control fluids and gas lift.

Valve Price Doesn’t Mean Everything

Usually many Distributor/Importer or Wholesaler of industrial valve, especially from third world country, they eveluate valve by several factor.1. price is most important  2. quality 3. after sales 4.delivery time  5. service 6. payment method… Other factors might change their rank, but price is most important for them.

Howover, we’d like to say Valve price doesn’t mean everything.  See below pic, we see this surprising pic in one factory when we visit their neighbour local recently.

IP code – Ingress Protection Ratings(valve actuator)

IP – Ingress Protection Ratings, also named as International Protection Rating, is used to specify the environmental protection – electrical enclosure – of electrical equipment. like valve electric actuator.

Ingress Protection (IP) ratings are developed by the European Committee for Electro Technical Standardization (CENELEC) (NEMA IEC 60529 Degrees of Protection Provided by Enclosures – IP Code), specifying the environmental protection the enclosure provides.
The IP rating normally has two (or three) numbers:
1. Protection from solid objects or materials
2. Protection from liquids (water)
3. Protection against mechanical impacts (commonly omitted, the third number is not a part of IEC 60529) Continue reading “IP code – Ingress Protection Ratings(valve actuator)”

Thermoplastic materials as valve seat

A large number of thermoplastic materials are offered in valves, mainly as soft-seat  options for ball valve applications. Also lined valves like, lined butterlfy valve, lined globe valve, lined check valve. For this reason, the following section outlines some of the fundamental aspects of the properties, capabilities and application of these materials.

Application of advanced technology in the domestic large pipeline valve:all welded ball valve

Application of advanced technology in the domestic large pipeline valve

Overview
All rely on imports in the year 2000 China’s large-scale all-welded pipeline ball valves. Localization process of digestion, absorption and innovation through the use of modern advanced design techniques, such as reverse engineering, screening engineering, numerical analysis of finite element method, anti-breaking design, the design of anti-corrosion, low torque design and advanced manufacturing technology and technology and equipment, was a success.
Reverse engineering technology and its applications

The key technology of all-welded body pipeline ball valves (Figure 1) is the body welding, welding ball valve assembly is the last step, not heat-treated. Therefore, the development of free weld heat treatment after welding technology research, anti-Sum learn the foreign pipeline valve welding process with technology product localization shortcut.
