Material of Construction : Valve design II ASTM Std
What you'll learn
- Material of Construction (MOC) II Valve Design II ASTM Stds
- •Carbon steel •High temperature steel •Low temperature Steel •Stainless steel
- Piping, Oil & Gas awareness
Valves are important part of piping systems. They have to be handled very delicately. Material has its own role while finalizing the piping design. Various codes and standards have to be referred. While referring to the ASTM standards, many clauses have to be referred.
1.Division of Materials in four categories
2.Based on forging and casting, the selection of 8 ASTM standards and 20 associated grades
3.Discussion on selected grades & ASTM in details :
•High temperature steel
•Low temperature Steel
Frequently Asked Questions:
How do you choose valve material?
The control valve user normally specifies the body material, which is often the same material as the pipe.
What is valve size?
The first step in finding the size of a valve is to determine the flow. coefficient (Cv) that is required for the system.
What is Cv in Valves?
Cv factor is defined as. “the number of US, gallons per minute of 60F water that will flow through. a fully open valve with a 1 psi drop across it”.
What is valve in piping?
Valves are mechanical devices that controls the flow and pressure within a system or process.
Why is carbon steel used in valves?
Carbon steel has high and low temperature strength, is very tough and has excellent fatigue strength. Mainly used in gate, globe, and check valves for applications up to 454ºC, and in one-, two-, and three-piece ball valves.
What are PVC valves?
A PVC or polyvinyl chloride ball valve is a plastic on and off valve that has a rotary ball with a bore where turning the ball a quarter turn can stop the flow of a fluid.
What is API standard for valves?
API 6D is the primary standard for valves used in pipeline service, including gate, plug, ball and check valves.
Which are the most commonly used material grades for body and trim of valve?
Monel – Is a nickel-copper alloy used primarily as interior trim on all types of valves.
What is WCB body material?
WCB is a grade of Carbon steel used for valve body . It is a type of ASTM A216 cast steel. WCB is suitable for large diameter valves.
What is the best valve guide material?
Silicone-brass content bronze is probably the most popular now - often with a high aluminium or manganese content - is very yellow/gold in colour
