Description
Making Materials:
The selection of materials for boiler tube shields is generally based on the initial design of the boiler. Different materials are resistant to temperature and mechanical strength.
Stainless steel material: 1Cr18Ni9Ti (321), Cr23Ni13 (3095), 1Cr20Ni14Si2, Cr25Ni20 (3105), 1Cr25Ni20Si2, also some low temperature areas (such as low temperature superheater, low temperature reheater) using 1Cr13, 1Cr6Si2Mo and other materials.
Appearance:
Shape of boiler tube shields mostly are semi-circular (180 degrees or 120~160 degrees), divided into straight shields, inner shields, external curved shields, side curved shields, S-shaped curved shields and so on.
Straight boiler tube shields are commonly used in lengths of 20mm-3000mm and 1000-2000mm;
Curved boiler tube shields are processed based on drawings. Following parameters needs to be provided: pipe outer diameter, pipe bending radius R (to the center of the pipe), bending angle and length of both sides of arc.
