Firm black HDPE stub end for fire protection systems

Short Description:

HDPE stub end, also known as HDPE flange adapter, is a flange seat with a short tube used for connecting pipes to each other. To form a flanging structure, stub end needs to be welded together with the pipe in advance, which is not removable. Then, it is assembled with flange, rubber ring and screws to form a detachable flanging jointing. The welding process requires the hot melt machine, but the installation and removal of screws only require manual operation. HDPE stud end has the characteristics of non-toxicity, corrosion resistance and easy installation. For safety, we recommend consumers to purchase and install under the guidance of professional engineers.

Product advantages

HDPE stub ends are designed to be quickly and easily installed onto the end of HDPE pipes using standard tools. This simplicity of installation can result in faster and less expensive installation costs.

The HDPE stub end's sealing system is designed to create a tight seal between the pipe and the fitting, preventing any leakage of liquids or gases.

HDPE stub ends are suitable for a wide range of applications, including water supply systems, pressure piping and more. Their popularity is due to their ability to withstand pressure, their leak-free sealing capabilities, and their durability in various environments.

The pipes and pipe fittings produced by Jiangyin Huada do not contain heavy metal additives, do not scale and do not breed bacteria, complying with the health and safety regulations of many countries and international organizations.

Jiangyin Huada supports color customization, size customization, OEM, ODM and other additional services with the aim of striving to provide the best service and meet customer procurement expectations.
