1.1 Characteristics of Jiadun Co., Ltd.'s liquid distribution tank body:

·Chemical stability of materials - no leaching. Made of non shedding and non-toxic materials. Commonly used are 304 and 316L stainless steel.

·Manufacturing and processing according to the quality assurance system for pressure vessels.

·Surface treatment - The surface in contact with the medium usually requires mechanical or electrochemical polishing treatment.

·Connection method - The container is welded with argon gas protection.

·Structure - Sterility and hygiene are the main requirements.

·Sealing - an excellent sealing system with sealing grade, working pressure, working temperature, anti cavitation effect, sterilization

·The process, cleaning process, and passivation process all need to be considered.

·There is a certain slope - allowing the liquid to be drained completely by its own gravity.

·The length to diameter ratio of pipe fittings and blind ends of pipelines - if the length to diameter ratio is too large, it can lead to material residue and the growth of microorganisms.

·Easy to connect - easy to connect with CIP and SIP systems.

（2） Manufacturing process of mixing tank

2.1 Advanced and complete processing flow ensures quality

Strict process control runs through the entire process. The entire process includes: material incoming inspection, cutting, plate forming, automatic welding (circumferential/longitudinal/special welding), assembly welding, X-ray inspection, mechanical polishing, pressure testing, sandblasting treatment, electrolytic polishing, etc.

2.2 Strictly follow the ASME BPE standard inspection process

We follow the design and manufacturing standards for pressure vessels and ASME BPE standards, and strictly implement material storage, material testing (including welding materials), weld inspection, pressure testing, smoothness testing, carbon and sulfur analysis, etc.
