Buyers can use the page to check whether the product, grade, size range, inspection requirements and delivery details match their inquiry.
Referred to as pressure and boiler vessel material, steel grade P235GH is well suited for use in elevated temperature applications. Pipes produced under standard EN10216-1 are a part of pressure systems. Hence, these components are able to perform well in both high pressure as well as high temperature applications. Industries such as the oil & gas, chemical and petrochemical industry prefer the use of EN10216-2 pipe dimesions as these sectors have highly demanding operations.
Usually, the conveyance of media across distilleries or refineries calls for high quality produced EN10216-2 P265GH equivalent because they undergo several stresses including viscosity of the media being passed or even the speed of the flow. The EN10216-2 P235GH is a grade that has several designations like the letters P, G and H, all of which provide the characteristic description of the pipe. While the letter P means the pipe is meant for pressure purposes, the letter H indicates it is a hollow section or hollow profile and lastly the letter G suggests general characteristics. The number 235 simply states the minimum yield strength of the EN10216-2 P265GH in N/mm2. These steel grades are available in two qualities TR 1& TR 2. Steel tubes intended for use in ambient temperature settings are referred to as EN10216-2 P235GH TC1 quality. Generally steel pipes belonging to quality TR 1 are a part of systems that are useful to ferry across media.
