High-Purity Stainless Steel Copy Forest Set for Sanitary Systems

Overview

The High-Purity Stainless Steel Copy Forest Set is a specialized fitting designed for creating leak-free, sanitary connections in high-purity fluid systems, typically used in pharmaceutical and biotech applications. Constructed from 316L stainless steel, this set includes a socket, ferrule, and nut, featuring a compression design that ensures aseptic conditions and particle-free performance.

Features

Aseptic Compression Design:

316L stainless steel components (socket, ferrule, nut) with electropolished surfaces (Ra ≤0.4μm), eliminating crevices and particle traps critical for sterile environments.

Compression fitting creates a gas-tight seal without welding, ideal for systems requiring frequent disassembly for cleaning or component replacement.

Precision Manufacturing:

Ferrule designed to bite into the tube surface (37° angle) for leak-proof connections, compliant with ASME B31.3 and 3-A Sanitary Standards.

Socket internal surface polished to Ra ≤0.2μm, reducing protein and residue buildup in biopharmaceutical processes.

Material & Performance:

316L stainless steel (extra low carbon) resists intergranular corrosion in welded systems, with a minimum yield strength of 205 MPa and temperature range from -40°C to 200°C.

Rated for working pressures up to 100 bar (1,450 PSI), suitable for high-pressure liquid chromatography (HPLC) and ultra-pure water systems.

Compliance & Certification:

Meet USP Class VI, EP 3.1.2, and cGMP guidelines, with material traceability and surface roughness reports available for regulatory audits.

Available in tube sizes 1/8" to 2" (6mm-50mm OD), with custom configurations for non-standard tube diameters.

Application

Perfect for high-purity fluid handling in critical industries:

Pharmaceutical Manufacturing: Connecting sterile water-for-injection (WFI) lines and bioreactor feed systems, compliant with EU GMP Annex 15 for aseptic processing.

Biotech Research: Creating leak-free connections in cell culture media lines and chromatography systems, preventing contamination in GMP-grade labs.

Semiconductor Fabrication: Ultra-pure water (UPW) and chemical mechanical planarization (CMP) fluid lines, with electropolished surfaces meeting SEMI standards for particle control.

Food & Beverage: Aseptic connections in dairy pasteurization and juice concentrate lines, ensuring no product degradation during transfer.

FAQ

Q: What is a copy forest fitting?

A: A compression fitting consisting of a socket, ferrule, and nut, used to connect tubes without welding, ideal for sanitary and high-purity systems.

Q: Can this fitting be reused?

A: Yes, the nut can be re-tightened, but replace the ferrule after disassembly to ensure a new seal, especially in high-purity applications.

Q: How to clean the fitting for CIP/SIP processes?

A: Use hot water (80°C) or chemical sanitizers (e.g., sodium hydroxide), ensuring all components are fully flushed and dried after cleaning.

Q: Is the fitting suitable for cryogenic applications?

A: Yes, 316L stainless steel maintains ductility at -196°C, making it ideal for liquid nitrogen and LNG transfer lines.
