Carbon steel Y-Strainers are used mainly in the oil and petrochemical industry. They have excellent resistance to mechanical or thermal shock and these are important consideration in the event of a fire. Most oil refineries will not permit iron piping components for this reason. Carbon steel Y-Strainers are also used for higher pressure applications because of their great strength.
Stainless steel Y-Strainers are used where high corrosion resistance or where freedom from contamination is required. They are popular in the chemical, food and pharmaceutical industries.
