Stainless steel High pressure Corrosion resistant PTFE flange tee

Aflange tee is a T‑shaped pipe fitting with flanged ends, used to form a branch connection in a pipeline. It is typically installed PTFE tee at intersections or diversion points of pipelines, allowing flow to split or combine between the main line and the branch. It is widely used in industrial, chemical, and fluid pipelines for reliable connection and easy maintenance. Common types include equal flange tee,reducing flange tee,stainless steel flange tee,andPTFE‑lined flange tee for corrosive service.

Flange tee is a type of tee fitting with integral flanged ends, while ordinary tees may use welded, threaded or quick-fit connections. The core difference lies in flange connection: stronger, leakproof and easy to install/dismantle. Our flange tee features premium stainless steel material, strict dimensional standard, full-pressure testing and durable sealing. We offer stable wall thickness, smooth lining, precise flange face and long service life, with better corrosion resistance and reliability than ordinary products, suitable for high-demand industrial pipelines.

F (Feature): Adopts integral flange structure (no separate flange welding); inner wall has optional PTFE lining and smooth polishing treatment (Ra ≤ 0.8μm for sanitary grade).

A (Advantage): Enhances connection firmness, avoids flange detachment, facilitates installation and dismantling; smooth lining and polishing prevent medium deposition, reduce fluid resistance, and are easy to clean.

B (Benefit): Suitable for high-demand scenarios such as chemical and food industries, ensures pipeline cleanliness, extends product service life, and reduces your equipment replacement cost.

F (Feature): Multiple structure designs available (equal/reducing flange tee, jacketed type); undergoes strict pressure testing (1.5 times working pressure); temperature resistance range is -20°C to 150°C.

A (Advantage): Diversified structures meet different pipeline branching and diverting needs; strict pressure and temperature resistance ensure stable operation under harsh working conditions.

B (Benefit): Reduces equipment failure rate, improves production efficiency, and avoids losses caused by equipment shutdown for your enterprise.

F (Feature): Flange face adopts RF/FF/MFM standard design; conforms to ASME B16.5, DIN, GB and other international standards; main body has uniform wall thickness and strong load-bearing capacity.

A (Advantage): Standardized flange design ensures perfect matching with existing pipeline systems; uniform wall thickness and strong load-bearing capacity improve product durability and corrosion resistance.

B (Benefit): Eliminates the need for custom adapters, reduces installation difficulty and cost; resists impact and corrosion, reduces replacement frequency, and saves your long-term procurement cost.

F (Feature): Customizable size (DN15-DN600), lining material and pressure rating; provides OEM/ODM service and sample customization; sealing ring adopts detachable design.

A (Advantage): Customizable solutions fully fit specific project needs; detachable sealing rings facilitate replacement; sample support helps verify product suitability in advance.

B (Benefit): Avoids the trouble of mismatched specifications, saves your trial cost and replacement time, improves project progress, and brings flexibility to your procurement and use.
