HDPE Butt Fusion Flange

Polyethylene butt fusion flanges are manufactured from high-density polyethylene HDPE – PE100 and are typically produced in pressure ratings of PN10 and PN16. These fittings are available in nominal diameters ranging from 63 mm to 800 mm and comply with international standards such as ISO 4427 and DIN 16963. Their operating temperature ranges from 0 to 60 degrees Celsius, and when UV-stabilized materials are used, their resistance to sunlight exposure is significantly enhanced. The weight of each flange varies based on nominal size and pressure class, typically ranging from 0.4 to 12 kilograms.

The connection process involves butt fusion welding, which provides a fully secure, leak-proof, and permanent joint between the flange and the polyethylene pipe. The weld length is generally considered to be 1.5 to 2 times the pipe diameter to ensure mechanical stability. The wall thickness of the flange is designed according to the PN rating and can reach up to 45 millimeters for PN16 pressure class. These flanges are ideal for pressurized systems, corrosive fluid transport, industrial wastewater, and potable water applications.

Long base polyethylene flange

Long base polyethylene flanges are typically made from high-density polyethylene HDPE with a density ranging from 0.94 to 0.96 grams per cubic centimeter. These flanges can withstand nominal pressures between 6 to 16 bar PN6 to PN16 and operate within a temperature range of -20 to +60 degrees Celsius. Their manufacturing standards generally comply with international norms such as ISO 4437 and ASTM F1055. The nominal diameter of these flanges usually varies from 20 millimeters up to 1200 millimeters, depending on project requirements.

The dimensions of the long base flange include a base height between 20 to 50 millimeters, designed to facilitate connection and enhance strength. The flange surface is produced either flat or grooved to ensure reliable sealing in piping systems. Due to the lightweight polyethylene material, these flanges are easy to install and transport. The long base flange can connect to polyethylene pipes and metal flanges via bolts or thermal fusion welding, making them widely used in water, wastewater, gas, and agricultural industries.

Threaded Polyethylene Flange

The threaded polyethylene flange is made from PE100 material and is designed to withstand working pressures of up to 16 bar. Its common sizes range from 20 to 315 millimeters, featuring standard BSP or NPT threads. With an operating temperature range of 0 to 60 degrees Celsius and high corrosion resistance, this flange is an ideal choice for polyethylene piping systems used in water supply and agricultural applications. If you are looking to buy a threaded polyethylene flange or a polyethylene threaded flange for high-pressure pipes, this product meets your needs.

This welded polyethylene flange is manufactured according to DIN 16963 and ISO 4437 standards, with mechanical strength of the threaded connection exceeding 5 megapascals. The flange body is designed to prevent leakage in water and industrial fluid pipelines. It is highly suitable for agricultural projects, drip irrigation, and urban water transmission systems. Additionally, its quick connection and easy disassembly features simplify installation and maintenance.

Short Base Flat Polyethylene Flange

The technical specifications of the flat polyethylene flange short base include high-density HDPE material, offering excellent mechanical and chemical resistance. The flange diameter ranges from 20 to 1200 millimeters and is selected according to the pipe size. It can withstand a working pressure of up to 16 bar PN16, making it widely used in water and gas transmission systems. The flange thickness is designed to uniformly withstand internal pressures and resist thermal and mechanical stresses. Its operating temperature range is defined between -40 to +60 degrees Celsius.

The flat polyethylene flange short base features a bolted connection that ensures reliable sealing. It is lightweight, allowing for quick and easy installation. High resistance to corrosion, acids, and alkalis, a service life exceeding 25 years, and full compliance with international ASTM and DIN standards are among its key features. The short base design enhances mechanical strength while reducing the overall weight of the piping system.
