We are delighted to announce the official release of our latest series of HDPE fittings!

Choosing the right pipes for a household water system is crucial to ensuring the safety and efficiency of water use.

HDPE and PVC are two commonly used plastic pipes, widely applied in construction, industry, and agriculture. Although both have their advantages, they also come with some drawbacks.

HDPE (High-Density Polyethylene) drainage pipes are widely used in drainage systems due to their excellent performance and long service life.

Choosing the right plumbing material is critical for ensuring the efficiency, safety, and longevity of plumbing systems.

This article explores the differences between PPR and PVC pipes to determine which one is better suited for various applications.

Electrofusion fittings are essential pipe connections, and their manufacturing process directly impacts the quality and performance of the products. In this article.

PPR pipes are widely used in hot and cold water systems, underfloor heating, and potable water supply due to their excellent thermal stability, corrosion resistance, and high pressure tolerance.

HDPE (High-Density Polyethylene) and PVC (Polyvinyl Chloride) are two commonly used plastic pipes, widely applied in construction, industry, and agriculture.

When selecting pipes for various applications, two popular materials are HDPE and PPR . Each material has its unique strengths, making them suitable for different uses.

HDPE is a thermoplastic resin with a high degree of crystallinity and non-polarity, characterized by high density and excellent chemical resistance.
