The standard proposed by China State Shipbuilding Corporation.

This standard by the National Marine Machinery Standardization Technical Committee (SAC/TC137) centralized.

1 Scope

This standard specifies the requirements for cleaning and cleanliness level of the hydraulic oil system piping. Piping and associated components of the hydraulic oil pipeline system Clean ensuring the normal work of the hydraulic system is very important.

This standard also provides a method for cleaning the hydraulic system with a special attachment parts and required equipment.

The purpose of cleaning is to remove contaminants left over during installation, check the piping and hydraulic systems to ensure adequate cleanliness.

When Reynolds Re<=3000, the cleaning process of the system is transparent wash; Re>=3000 when the Reynolds number, the cleaning process of the system is flushed.

Reynolds is laminar or turbulent fluid is an indicator.

This standard assumes that the hydraulic system piping cleaning can be part of the pickling method, partly by mechanical means. Further, assume that the supply system Supplied motion components and stationary components are sufficiently clean (see Chapter 5).

Each manufacturer has a product for cleaning and cleanliness standards, the requirements of this proposed standard is its complement, and not replace generation. Where feasible, the priority use the manufacturer's product cleanliness requirements and cleaning guidelines.
