Straight Shields are available with angles of wrap between 90º to 240º and can be manufactured with straight ends, belled ends and flared legs. Complete coverage is available by overlapping shields.
Curved Shields can be manufactured to cover both outside and inside curves of tubing. Angle of wrap and degree of bend is always 180º. Complete coverage is available by overlapping shields.
Special design provides effective protection for finned tubes. Economizer Shields can be manufactured to accommodate tube OD, angle of wrap and fin height. Angle of wrap is available between 60º and 240º with fin heights ranging from 1.50" to 2.25".
For "new" shop applications, the 370º Tube Shield allows for complete coverage of tube surface without the need for overlapping two shields. Available in straight lengths only.
Clips are the recommended method for tube shield attachment. Choose from Bull Style, Wrap Style or Overlap Style.
