What are the piping requirements for purified water equipment systems subject to GMP certification?

The following content is from Shenzhen Kerui and is for reference only (1) The treatment pipeline should be installed through the ceiling and into the water point (not through the floor) to avoid retention of process water in the pipeline; the circulation loop should not be If the installation is too low, the water inlet pipeline should not be installed too low, which may result in a risk of two-way contamination; pipeline design and installation should avoid dead corners and blind pipes installed horizontally; pipes must be adjusted at an angle of inclination; there must be some inclination on the pipes, to facilitate the drainage and storage of water; the length of the dead angle at the point of use of the valve should not be more than 3 times the inner diameter; of the branch pipe; terminal water outlet uses genusually a circulation pipe. (2) Select reliable quality diaphragm valves and pipes with polished interior surfaces and passivate them. Ensure that the flow speed in the water storage pipeline should be greater than 2 m/s; (3) Process water storage tanks, fittings, and piping shall be constructed of nontoxic, corrosion-resistant materials, and shall not be polyvinyl. chloride; use sanitary pipes and connection methods; Pipelines and storage tanks must be passivated before first use. Storage tanks and pipelines must be made of 304L and 316L stainless steel. In the pre-treatment stage, pipes should be made of ABS engineering plastics and other materials resistant to pressure and corrosion. After high pressure reverse osmosis pump, stainless steelmust be used. The valves of the main pipe and branch pipes of the pipeline shall be made of stainless steel diaphragm materials. (4) The pipes are connected by hot welding or argon arc welding, or by sections filled with domestic water. The installation of pipes must ensure that the water in all pipes can be discharged; the slope is usually stipulated as 1% of the pipe length, which applies to both water for injection and purified water pipelines in case of water accumulation in the pipes, drainage; points or valves must be installed; the number of drainage points should be Try to keep it to a minimum

Two purified water storage tanks can be connected to each other, but they must comply with GMP requirements. GMP refers to good manufacturing practices for pharmaceutical products, which aim to ensure the quality and safety of pharmaceutical products.ceuticals. In the pharmaceutical production process, purified water constitutes a very important link, which is why GMP requirements must be strictly respected.

First of all, the connection between the two purified water storage tanks must meet the hygienic requirements of GMP. Connecting parts must be flat, without dead corners and must not contain any contaminants or foreign object residue. Connections must use hygienic grade pipes and joints meeting GMP requirements to ensure water purity.

Secondly, the pipeline connecting the two purified water storage tanks must comply with GMP requirements. Pipes should be made of materials meeting GMP requirements, such as stainless steel, etc., to ensure corrosion resistance and high temperature resistance of pipelines. The design and installation of pipes must bealso comply with GMP requirements to guarantee the hygiene and reliability of the pipes.

Finally, the operation of connecting two purified water storage tanks must comply with GMP requirements. Operators must receive professional training and understand GMP requirements and operational procedures. During the operation, GMP requirements must be strictly followed, such as wearing sanitary clothing, masks, gloves, etc., to ensure the hygiene and safety of the operation.

In short, two purified water storage tanks can be connected to each other, but they must meet GMP requirements. Only by strictly complying with GMP requirements can the quality and safety of purified water and the quality and safety of pharmaceutical production be guaranteed.Safety.
