Full scale model HDPE reducing coupling used in pipeline system

Short Description:

The role of reducing coupling is to connect two pipes of different sizes. Due to the nature of the reducing coupling, it can be regarded as a bridge between two pipes or pipe fittings of different specifications, it cannot change the direction of the pipeline. The heat fusion reducing coupling are divided into two series, socket fusion and butt fusion, which are respectively connected to HDPE pipe by different types of hot melt welding machines. The adoption of 100% HDPE new material makes our products meet the standards of direct drinking water, so they are widely used in government water supply projects, agricultural irrigation, water supplies for fire protection systems, etc. For safety, we recommend consumers to purchase and install under the guidance of professional engineers.

Product advantages

HDPE pipes and pipe fittings can be used safely in the temperature range of -60~60℃ in the external working environment.

HDPE pipe and pipe fitting have good flexibility and impact resistance. That’s the reason why they can be suitable for many different types of complex terrain and extreme weather.

The unique connection technology ensures the safety and reliability of the interface, whose strength can even be higher than the pipe, leading to a closed water supply or drainage system inside the pipeline.

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.
