Ürün Detayı
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, dozaj sistemleri, and light-duty process piping.
SASA FLANGE supplies PTFE threaded flanges in standard and customized dimensions with options in virgin PTFE, filled PTFE, and PTFE-lined metallic backing constructions. Every order can be supported by chemical analysis of metallic components, mekanik test, boyutsal muayene, PMI testing for stainless or alloy backing flanges, EN 10204 3.1 sertifika, and full heat number traceability to meet international project requirements.

SSS
Q: What is a PTFE threaded flange?
A: A PTFE threaded flange is a screwed flange designed with an internal thread so it can be connected to threaded pipe without welding. It is made from pure PTFE, filled PTFE, or PTFE-lined metal-backed construction. This type is mainly used in corrosive service, light to medium pressure piping, and systems where quick installation or maintenance is required.
Q: What materials are available for PTFE threaded flanges?
A: SASA FLANGE can supply PTFE threaded flanges in virgin PTFE, glass-filled PTFE, carbon-filled PTFE, and PTFE-lined carbon steel or stainless steel construction. For reinforced designs, common metallic backing materials include ASTM A105, ASTM A182 F304, Ve ASTM A182 F316. Material selection depends on chemical media, servis sıcaklığı, basınç, and mechanical load.
Q: Hangi basınç sınıfı destekleniyor?
A: PTFE threaded flanges are commonly supplied in ASME Class 150 ve Sınıf 300, or EN/DIN pressure ratings such as PN10, PN16, PN25, and PN40 depending on size and design. Because PTFE is softer than forged steel, the final pressure capability must consider temperature, medya, construction type, and whether the flange is solid PTFE or PTFE-lined with metal backing.
Q: Olabilmek SASA FLANGE özel boyutlar sağlayın?
A: Evet. SASA FLANGE can produce PTFE threaded flanges in custom dimensions, delme desenleri, flange thicknesses, sealing faces, and thread forms including NPT, BSPT, and BSPP.
