Bimetal Composite Pipe Fluid Transfer Solution for Pharmaceutical & Food & Beverage Industries<\/h3>\n
\n

The pharmaceutical and food & beverage industries have extremely high requirements for fluid conveyance pipelines. Traditional pipes face multiple pain points in practical applications:
Health and Safety Risks\nTraditional carbon steel pipes are prone to rust and scaling, which can contaminate media such as liquid medicines, purified water, and beverage stock solutions, affecting product purity and food safety; welds of some stainless steel pipes are prone to intergranular corrosion, breeding microorganisms and causing batch contamination.<\/p>\n\n\n\n


Insufficient Corrosion Resistance:\nAcid-base components in liquid medicines, organic acids in food and beverages, high-sugar\/high-salt media, as well as high-temperature acid-base during CIP\/SIP cleaning processes, can corrode the inner wall of pipes, leading to media contamination and pipe failure.<\/p>\n\n\n\n


Conflict Between Cost and Service Life:\nPure high-grade stainless steel or special alloy pipes have high procurement and maintenance costs, while ordinary stainless steel pipes have insufficient corrosion resistance. Frequent replacement will affect production continuity and increase operation and maintenance costs.<\/p>\n\n\n\n


Compliance Pressure:\nPipeline systems need to meet industry standards such as GMP, FDA 21 CFR, and 3-A. Traditional pipes are difficult to balance hygiene, corrosion resistance and economy, and cannot adapt to high-standard production requirements.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Our bimetallic composite pipes adopt a composite structure of \"hygienic corrosion-resistant alloy inner liner + high-strength carbon steel outer layer\", providing a fluid conveyance solution that balances safety, compliance and cost for the pharmaceutical and food & beverage industries:<\/p>\n\n\n\n


Hygienic Corrosion-Resistant Alloy Inner Liner:
<\/strong> Selected food\/pharmaceutical grade stainless steel such as 316L, 304L and duplex steel, the inner wall is polished with low roughness, not easy to scale and free of dead corners. It can resist corrosion from liquid medicines, food media and CIP\/SIP cleaning media, meeting the requirements of hygienic fluid conveyance.<\/p>\n\n\n\n


High-Strength Carbon Steel Outer Layer:<\/strong>
High-quality carbon steel is used as the base layer to provide sufficient structural strength and pressure-bearing capacity, adapting to pressure conveyance and hoisting installation conditions in the plant, while reducing the overall pipe cost.<\/p>\n\n\n\n


Reliable Composite Process:<\/strong>
The double layers are tightly combined through mechanical composite or metallurgical composite, with no gap between the inner liner and the outer layer. The inner wall is smooth and flat, and conventional hygienic welding processes can be adopted to meet the cleaning and sterility requirements of GMP for pipeline systems.<\/p>\n\n\n\n


Typical Application Scenarios<\/strong>
Pharmaceutical Industry:\nPurified water\/injection water conveyance pipelines, liquid medicine conveyance pipes, supporting pipelines for biological fermentation tanks, and CIP\/SIP cleaning system pipelines.
Food & Beverage Industry:\nBeverage stock solution conveyance pipelines, dairy\/beer\/brewing process pipelines, food additive conveyance pipes, and high-temperature sterilization system pipelines.<\/p>\n\n\n\n


Core Advantages of the Solution<\/strong>
\u2705 Hygienic and Safe, Eliminating Contamination: The food\/pharmaceutical grade inner liner alloy has a smooth and corrosion-resistant inner wall, no precipitation or dissolution, avoiding media contamination, ensuring product purity and food safety, and complying with industry standards such as GMP and FDA.
\u2705 Long-Term Corrosion Resistance, Adapting to Complex Working Conditions: The inner liner can resist corrosion from organic acids, acid-base cleaning fluids, and high-salt and high-sugar media, reducing the risk of pitting and crevice corrosion, extending the service life of pipes, and reducing replacement frequency.
\u2705 Cost Reduction and Efficiency Improvement, Balancing Economy: Compared with pure high-grade stainless steel pipes, bimetallic composite pipes can significantly reduce procurement costs, while reducing losses caused by production suspension and maintenance, and batch scrapping due to pipe corrosion, improving production continuity.
\u2705 Compliance Adaptation, Full-Scenario Coverage: Customizable inner liner materials and specifications are available to adapt to different hygiene level requirements from low to high in the pharmaceutical and food & beverage industries. It can be matched with hygienic pipe fittings and valves to achieve a system-level compliance solution.<\/p>\n\n\n\n
