Название: Ductile-Iron and Gray-Iron Fittings ISBN: 1647170788 ISBN-13(EAN): 9781647170783 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 21483.00 р. Наличие на складе: Нет в наличии.
Описание: This standard covers 76 to 1,219-mm gray-iron and/or ductile-iron fittings to be used with ductile-iron pipe for water. Requirements for fittings with mechanical joints and flanged joints are listed in Tables 1 t o20 at the end of this standard. This standard may also be used for fittings with push-on joints.
Описание: The effects of air and vacuum pockets present in a liquid piping system can negatively impact not only pump, meter, and control valve operation but can also be responsible for pipeline breaks and collapses. Choosing and installing the correct air valve is critical to all liquid piping systems. This manual of practice provides essential information for selecting, sizing, locating, and installing air valves in water, wastewater and reclaimed water pipeline systems. This revised second edition includes information pertaining to wastewater applications including scouring velocities for larger piping systems, and information on an inflow preventer device installed to protect from malicious tampering, freeze and flood, and to prevent the entry of contaminated water into the potable water distribution system. Operators, technicians, and engineers will use this manual to understand the design, use, application and maintenance of air valves. The air valve types listed in both ANSI/AWWA Standard C512, Air Release Valves, Air/Vacuum, and Combination Air Valves for Water and Wastewater Service and ANSI/AWWA C514, Air Valve and Vent Inflow Preventer Assemblies for Potable Water Distribution System and Storage Facilities are covered. Chapter topics include: locating air valves along a pipeline; design of valve orifice size; water hammer effects; and installation, operation, maintenance, and safety.
Описание: Describes electric motor actuators for valves and slide gates in water, wastewater, and reclaimed water utility systems. Electric motor actuators are designed to produce a multiturn rotary motion output to actuate a multiturn valve or gate or to actuate an external gearhead for quarter-turn valves.
Описание: Describes hydraulic and pneumatic linear and quarter-turn actuators for operation of valves and slide gates in utility systems. The standard defines the minimum requirements for hydraulic and pneumatic actuators, such as sizing considerations, general design, materials, applications, painting and coatings, and data to be furnished by manufacturer.
Описание: Describes resilient-seated cast-iron eccentric plug valves, 3 in. (75 mm) through 72 in. (1,800 mm) in diameter, with flanged, grooved, or mechanical-joint ends, for water, wastewater, and reclaimed water systems having a pH range from 6 to 12 and a temperature range from 33F to 125F.
Описание: The purpose of this standard is to provide the minimum requirements for fusion-bonded epoxy coatings and linings for steel water pipelines and fittings, including materials, application, and testing. This standard can be referenced in documents for fusion-bonded epoxy coatings and linings for steel water pipelines and fittings.
Описание: Provides information on valve selection and installation as well as the importance of location, condition, and frequency of operation. Also includes the latest methodologies and technologies for handling, inspecting, shipping, and storing valves and their associated parts.
