What is a hdpe stub flange?

September 10, 2024

Stub end flange is a pipe connector, mainly used for pressure transmission and sealing at pipe joints. It consists of a flange and a short pipe. By connecting two pipes together, the pressure in the pipe can be transmitted and balanced, so that the fluid in the pipe can flow smoothly. Flange short pipes are widely used and can be applied to various industrial fields, such as chemical, petroleum, natural gas, electricity, pharmaceuticals, etc.

HDPE stub flanges are used in piping as part of a fitting for the purpose of redirecting or changing pipes diameter. They are usually produced during the process of casting machinery components and molding.
HDPE stub flanges are butt welded to the ends of pipes and fittings and used in conjunction with metal backing plates, and rubber sealing gaskets provide a demountable joint. Sealing gaskets are made from various materials to suit the liquid being carried.

Flanges are available from 63mm to 1400mm(ASTM: 2-54 inch) and Common pressure  SDR11-PN16 Bar, SDR13.6-PN12.5 Bar, SDR17-PN10 Bar, SDR21-PN6 Bar, SDR26-PN6 Bar to suit the pipe and fittings.

Advantages and characteristics

1. Connection method: Stub end flange connects two pipes or equipment together through bolts and nuts to form a tight seal to prevent fluid leakage.

2. Sealing performance: It has good sealing performance and can ensure efficient fluid flow in the system to prevent leakage.

3. Scope of application: It is widely used in various industries, such as oil and gas, petrochemical, manufacturing, etc., for connecting pipes to valves or equipment, or connecting with another pipeline shaft.

4. Diverse types: Stub end flange has many types, each with its unique functions and advantages

Stub end flange is an indispensable part of the pipeline system, and its correct selection and use are essential to ensure the safe operation and efficiency of the system. Different types of stub end flanges are suitable for different application scenarios. When choosing, you need to consider factors such as pipe pressure, temperature, and medium properties.‌‌‌
