The use of stainless steel waterproof casing.

Stainless steel waterproof casing can be divided into: stainless steel rigid waterproof casing and stainless steel flexible waterproof casing two. Both also have the characteristics of anti-corrosion, good sealing, pressure resistance and impact resistance. The main material of stainless steel waterproof casing is steel, its own performance characteristics, including high hardness, good sealing, high pressure strength, anti-corrosion, good durability and other characteristics. Its waterproof principle is: a sealing part, formed on the inner circumference of at least one through-hole through which the wire of the connecting contact member is made to pass, in close contact with said wire; and a second sealing part, formed on the outer circumference, in close contact with the connector housing. It is characterized by the fact that one part with the above-mentioned sealing part is formed by an elastic material with lower hardness than the two parts with the above-mentioned second sealing part. The purpose of waterproofing is achieved. Function and role of waterproof casing through the wall (pool, plate, etc.). After the installation is allowed to have the amount of deformation - flexible waterproof casing; not allowed to have the amount of deformation - rigid waterproof casing. In the use of the environment is different, for internal and external sealing, high hardness, pressure resistance, high anti-corrosion needs in the general underground waterproofing project, suitable for the use of rigid stainless steel waterproof casing. In the use environment, slope, human defense wall and other special buildings, sealing, good hardness, pressure resistance, high flexibility needs, suitable for the use of flexible stainless steel waterproof casing.
