  What Is Steam? Saturation, Enthalpy, Dryness and Flash Steam

  Posted in: Engineering guides

  Steam is the vapour phase of water, and its behaviour is closely connected to pressure, temperature and the energy state of the water from which it is produced. For industrial steam engineering, it is not enough to state that water boils and becomes steam. It is necessary to understand saturation, the energy required for evaporation, the effect of pressure on specific volume, the meaning of dryness fraction and the mechanism that produces flash steam when hot condensate is reduced to a lower...

  SI Units and Core Thermodynamic Quantities in Steam Engineering

  Posted in: Engineering guides

  Steam engineering calculations depend on a consistent system of units. Pressure, temperature, energy, power, density, specific volume and enthalpy are closely related, and an incorrect unit or pressure reference can change the meaning of an otherwise correct calculation. The International System of Units, SI, provides a common basis for expressing mechanical and thermal properties. In steam engineering, the most frequently used base quantities include length, mass, time and temperature,...

  Industrial steam systems: from the boiler house to condensate return

  Posted in: Engineering guides

  In an industrial plant, steam is more than a hot fluid. It is an energy carrier generated centrally, distributed through pipework and used to deliver controlled heat at the point of demand. The system depends on the pressure-temperature relationship of saturated steam and on the energy released when steam condenses. From an engineering perspective, steam should be assessed as a complete loop: generation, distribution, pressure and flow control, heat transfer, condensate drainage, condensate...

  ISO 9001 Quality Management Systems (QMS)

  Posted in: Technical Standards Library, ISO Standards

  ISO 9001 is the internationally recognized standard for Quality Management Systems (QMS). It specifies the requirements for organizations to consistently provide products and services that meet customer expectations, applicable regulations and continual improvement objectives. The standard is applicable across all industries and is widely adopted by manufacturers of industrial valves, pressure equipment, piping systems, automation products and other engineered industrial solutions.

  ISO 9606 Welder Qualification Testing

  Posted in: Technical Standards Library, ISO Standards

  ISO 9606 is the international standard specifying the qualification testing requirements for welders performing fusion welding on metallic materials. It demonstrates that a welder has the practical skills required to produce sound welds that meet defined quality and safety requirements. The standard is widely applied in the manufacture of industrial valves, pressure vessels, piping systems, boilers, heat exchangers, structural steelwork, shipbuilding and power generation equipment.

  ISO 10497 Fire Type Testing for Industrial Valves

  Posted in: Technical Standards Library, ISO Standards

  ISO 10497 is the international standard that specifies fire type testing requirements for industrial valves. The standard verifies that a valve can maintain acceptable pressure integrity, external leakage control and seat tightness after exposure to fire conditions. Fire-safe certification according to ISO 10497 is widely specified in oil and gas facilities, refineries, petrochemical plants, LNG terminals, hydrogen systems and other high-risk industrial applications where valve performance...
