ASTM A335 P11 pipe

How cold drawn ASTM A335 P11 Pipe are manufactured

Cold drawn pipes are manufactured through a precise & specialized process. High quality P11 alloy steel is selected and heated to a suitable temperature. The heated billet is then subjected to a series of drawing processes to achieve the desired dimensions.

This cold drawing process improves the mechanical properties of the ASTM A335 P11 Pipe, like strength & dimensional accuracy. The UNS K11597 Welded Pipe exhibits an excellent surface finish, tight tolerances and improved resistance to corrosion & high temp environments. This manufacturing technique ensures the pipe meets stringent quality standards and performs reliably in various applications.

Can we do fabrication and machining on P11 Steel Pipe?

Fabrication & machining can be performed on P11 pipes. This steel grade has higher strength and hardness compared to carbon steels making it more challenging to work with. Proper tools, equipment & techniques should be employed to ensure successful fabrication and machining of the P11 Steel Pipe.

Avoid excessive heat input during welding to prevent microstructural changes and maintain the desired mechanical properties. Also, post-weld heat treatment may be necessary to restore the SA 335 gr P11 Seamless Pipe material’s properties after fabrication.

What are various ends available for ASTM A335 P11 Pipe and their uses

The commonly available ends for SA 335 Grade P11 pipes are plain ends, beveled ends, and threaded ends. Plain ends are typically used for butt welding or socket welding connections. Beveled ends are useful for welding applications, providing a smooth transition for proper joint alignment. Threaded ends allow for easy installation using threaded fittings.

Which surface treatment should be done Chrome Moly P11 Pipes

Chrome Moly P11 Pipes can benefit from surface treatments to enhance their performance and longevity. One common surface treatment on pipes made of ASTM A335 Gr P11 material is pickling. It removes oxide scales and impurities from the pipe’s surface, improving corrosion resistance.

Passivation is another treatment that forms a protective oxide layer on the surface, further enhancing corrosion resistance. Additionally, a coating such as painting or galvanizing can provide an extra layer of protection against corrosion and external damage.

How to perform flattening and hardness test on A335 P11 Boiler Pipe?

To perform the flattening test on an A335 P11 Boiler pipes, a section of the pipe is flattened with the help of a hydraulic press. The pipe is examined for any signs of cracks/ other deformities. This test ensures the pipe’s ability to withstand deformation without failure.

A small sample is taken from the pipes for hardness test. It is then subjected to an indentation test using a hardness tester. The indentation depth is measured & the hardness value is determined using a hardness scale. This test provides information about the pipe’s hardness properties, like its mechanical strength & suitability for specific applications.
