Metinox Overseas is a supplier and trader of Alloy Steel P91 Pipes engineered to be used in high-stress and high-temperature. Alloying elements in these pipes are meant to produce solid solutions, compounds or carbides, which in their own way play a significant role in the metallurgical performance of the material. These alloying elements too influence eutectoid temperature of the Alloy Steel P91 seamless pipes. Manganese and nickel are considered as austenite stabilizers, that is, they reduce the eutectoid temperature; and when they are present in adequate concentrations, they permit the austenitic structure of Alloy Steel P91 pipes to be stable even at room temperature. In heavy and crude oil conditions, pipes of the P91 alloy steel may experience the deposition of complex organic compounds, which may cause severe problems to the functioning of the pipes such as the decreasing flow rate and the possibility of the blockage of the pipeline. Consequently, the AS P91 pipes are designed specifically to work in the energy sector like oil and gas exploration whereby the components are regularly subjected to mechanical and thermal stresses.

AS P91 smooth pipes are used on minimum and nominal wall thickness on pipes made of ferritic alloy steel that are to be used in service at high temperatures. To determine the behavior of the performance evaluation, test pipes loaded with the AS P91 pipes are chilled to the desired temperature to evaluate the behavior under a controlled condition. Overall, wear resistance of the P91 alloy steel pipes (EN 1.4903) may be improved through the hardening of the material, the use of alloys with higher carbon content without acting on the hardness, or a combination of both. AS P91 (K91560) pipes have high mechanical properties both at ambient and higher temperatures up to 930 deg F (500 deg C) and can be easily made through normal industrial processes of manufacturing.
