Positive Material Identification (PMI) of stainless steel sheets for tube shields is critical to verifying the grade and composition of stainless steel before it goes into production.

Tubes Erosion Shields are used to reduce excess wear of boiler tubes within the extreme conditions prevalent inside a fossil fuel fired boiler, Sunny Steel is able to manufacture and supply erosion shield solutions to protect and reduce wear in all applicable boiler related situations.

The production time is short, the welding performance is good, the welding seam does not fall off, the surface is smooth and the appearance is beautiful. The arc-shaped wear-resistant tile is pressed on a press or bent on a pipe bender with a special mould.

PMI (Positive Material Identification) testing for tube shields is the analysis of materials to determine the chemical composition of a metal or alloy at particular (usually multiple) steps of alloy manufacturing or in-process alloy installation.
