Inox corrugated stainless steel pipes are provided with silicone O’ ring and PTFE grommet, the use of these seals allows INOX CSSP to form a dielectric waterway connection with standard Push-fit fitting.

FITTING

The following diagram illustrates the method of connecting:

MATERIAL COMPOSITION

INOX CSSPs are manufactured from 304L graded stainless steel (annealed)

Other grades of stainless steel, such as 316 are available to order.

CORROSION RESISTANCE LIMITATIONS

INOX standard CSSPs are manufactured from 304L grade stainless steel, which provides a good corrosion resistance for most application.

However, under certain conditions, such as very high chlorides levels, a different grade of stainless steel would be required.

FRICTION LOSS & PIPE SIZING

Corrugated stainless steel pipes generate a higher friction loss than that of smooth bore pipes. Pipes size selection should be done in a manner that will compensate for CSSPs friction and allow for the required supply, at the fixture, under peak conditions. The following chart provides an approximate pressure drop for each of INOX CSSP sizes; please consult the chart prior to design.

PRODUCT IDENTIFICATION

INOX CSSPs are marked at one metre intervals with the following:
