Main technical parameters:

Standard Type: P ≤ 2.5 MPa, T ≤ 350℃

High-temperature, medium-pressure: P ≤ 5 MPa, T ≤ 500℃

Specification range: DN50–DN1400

Swing angle: ±15°

Implementation Standard: QNYDJ006-2015

Model: FH.WXB (Nominal Diameter) – (Pressure) – (Temperature) – ± (Angle)

Scope of Application:

1. High‑temperature hot water, steam overhead lines, and pipe rack pipelines

2. Pipeline Networks in Cities and Mountainous Areas with Complex Topography

3. Pipelines with long lengths and low pressure drop requirements.

4. Pipeline networks that traverse special operating environments such as roads, bridges, and rivers.

5. Pipe networks with various deformations and complex operating conditions

Product Features:

1. Large compensation capacity, small footprint, low fluid resistance, and self‑balancing blind flange forces.

2. It adopts a pouring-type structure with excellent sealing performance.

3. It uses high‑purity flexible graphite, which boasts excellent sealing performance, high temperature resistance, anti‑aging properties, corrosion resistance, superior self‑lubricating characteristics, and a low coefficient of friction, with a service life exceeding 30 years.
