제품 세부정보
PTFE threaded flanges are non-welded flange components designed with female threaded bores for direct connection to threaded pipe or fittings. They combine the chemical resistance and low friction of PTFE with practical assembly in systems where welding is not preferred. These flanges are commonly used for corrosive media handling, low to medium pressure chemical lines, water treatment skids, dosing systems, and light-duty process piping.
SASA FLANGE supplies PTFE threaded flanges in standard and customized dimensions with options in virgin PTFE, 채워진 PTFE, and PTFE-lined metallic backing constructions. Every order can be supported by chemical analysis of metallic components, 기계적 테스트, 치수검사, PMI testing for stainless or alloy backing flanges, EN 10204 3.1 자격증, and full heat number traceability to meet international project requirements.

기계적 성질
Mechanical properties vary according to flange construction, selected metallic backing grade, processing method, and service temperature. PTFE itself is a soft corrosion-resistant material with lower strength than forged steel, so pressure capability is determined by design and reinforcement. The values below are typical reference data for common PTFE and backing flange materials used in threaded flange assemblies.

제품검사
1. 화학성분 검사
For PTFE-lined and metallic backed threaded flanges, chemical analysis is performed on the steel or stainless backing materials to confirm compliance with the specified grade such as ASTM A105 or A182 F316. PTFE raw materials are verified against internal quality requirements for purity and filler ratio to ensure suitable corrosion resistance and processing consistency.
2. 기계적 성질 테스트
Mechanical testing is carried out on the metallic backing flange material according to the applicable standard and project requirement. Typical tests include tensile strength, 항복강도, 연장, and hardness. For PTFE components, density and visual integrity are checked to support dimensional stability and service performance in threaded assembly applications.
3. 치수검사
Each PTFE threaded flange is inspected for outside diameter, 두께, 볼트 서클, 볼트 구멍 크기, flange face flatness, and thread accuracy. Sealing face finish and concentricity are also checked to ensure proper mating with valves, 피팅, and threaded pipe ends. Inspection records can be provided to support project QA documentation.
