What is PTC 6?

Table of Contents

ASME PTC 6, 2004 Edition, 2004 – Steam Turbines. This Code may be used for testing of steam turbines operating either with a significant amount of superheat in the initial steam (typically fossil-fueled units) or predominantly within the moisture region (typically nuclear-fueled units).

What is asme PTC?

ASME Performance Test Codes (PTCs) provide uniform rules and procedures for the planning, preparation, execution, and reporting of performance test results. They provide protocols for establishing testing parameters and methods of measurement.

What is the performance test code for steam turbine performance testing?

ASME PTC 6: Steam turbine performance test code. IEC 953: Rules for steam turbine thermal acceptance tests.

What is enthalpy drop test?

Enthalpy Drop Test. The Enthalpy Drop Test is used frequently for monitoring steam turbines. This test involves a minimum number of instruments, but estab- lishes the efficiency of those turbine sections most susceptible to deterioration.

What is the full form of ASME?

The American Society Of Mechanical Engineers.

What are performance test codes?

Performance test codes, otherwise known as PTCs, are standard documents, written and published by the American Society of Mechanical Engineers (ASME), that provide uniform rules and procedures for the planning, preparation, execution, and reporting of performance test results for different instruments, equipment, and …

What are steam turbines made of?

The nickel-based blades are alloyed with aluminum and titanium to improve strength and creep resistance. The microstructure of these alloys is composed of different regions of composition.

What is Curtis turbine?

The Curtis turbine is a compound impulse turbine, the com- pounding being both for pressure and velocity. In an impulse turbine, the internal energy of the steam is first changed into velocity, by expansion in a suitable nozzle, and the jet of steam directed against the moving blades.

How many ASME standards are there?

ASME’s standards portfolio includes over 500 standards and associated products. These products cover a breadth of topics, including pressure technology, nuclear plants, elevators / escalators, construction, engineering design, standardization, and performance testing.

Where are ASME standards used?

ASME is one of the oldest standards-developing organizations in America. It produces approximately 600 codes and standards covering many technical areas, such as fasteners, plumbing fixtures, elevators, pipelines, and power plant systems and components.

How many types of hydro tests are there?

There are three common hydrostatic testing techniques that are used to test small pressure vessels and cylinders: the water jacket method, the direct expansion method, and the proof testing method.

What should be considered when developing an ASME PTC?

Precision and reliability of test results must also underlie all considerations in the development of an ASME PTC, consistent with economic considerations as judged appropriate by each technical committee under the jurisdiction of the ASME Board on Standardization and Testing. Order any of the PTCs below:

What is the PTC 6 code?

The Code includes the methodology for determining the uncertainty of both the test and corrected results. PTC 6, on Steam Turbines, is the international standard for steam turbine acceptance testing. It was created and recently revised by a consensus group of vendors, owners, and users.

What are the ASME performance test codes?

Why choose ASME for power plant testing?

For over 100 years, ASME has been providing industry with a comprehensive collection of the best technical documents to conduct tests of power plant equipment and systems.
