Product Description
The astm a335 P91 pipe is a seamless Pipe meant for high temperature applications. These pipes are made from ferritic Alloy-Steel.Chemically the a335 P91 welded pipe contains elements like Molybdenum (Mo) and Chromium added to the alloy. When Molybdenum and chromium are added to the alloy, there is an increase in the tensile strength of the sa335 grade P91 pipe. The tensile strength of the a335 grade P91 pipe is 415 Mpa, while its yield strength is 205 Mpa. The elongation percentage of the pipe ranges between 20% to 30%. Alloy Steel P91 Seamless Pipes is often referred to as excellent steel due to its increased resistance to chloride corrosion making it a very suitable material for use in salt water environments.

Packing and delivery
Steel having a hollow section whose length is much greater than its diameter or circumference.According to the section shape is divided into round, square, rectangular and special-shaped steel pipe; According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to its use, it is divided into pipe transportation,engineeringstructure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, steel pipe with high pressure equipment, etc. According to the production process, it is divided into seamless steel pipe and welded steel pipe. The seamless steel pipe is divided into hot rolled and cold rolled (drawing) two kinds, and the welded steel pipe is divided into straight welded steel pipe and spiral welded steel pipe.
