Proper temperature control is the most critical factor in PE pipe welding. This article explains how temperature, heating time, and material differences affect fusion quality, and outlines common problems in butt fusion and electrofusion processes — helping ensure long-term pipeline reliability.

The quality of electrofusion welding depends on proper scraping, stable voltage and current, and strict adherence to different standards for gas and water pipelines.

PE80 and PE100 pipes should not be butt fused if their MFR difference exceeds 0.5 — electrofusion is the safe choice.

Choosing the right HDPE pipe fittings is key to building a reliable piping system. This article introduces the most common polyethylene pipe fittings—such as elbows, tees, reducers, flanges, and threaded fittings—and explains how to select between butt fusion and electrofusion connections. With high-quality high density polyethylene pipe fittings, Welping ensures durability, safety, and efficiency in every project.

Discover how Welping polyethylene pipe fittings are made — from raw material selection to precise molding and careful finishing. Learn why imported black resin and UV-resistant masterbatch ensure durability, and why avoiding recycled material is key to preventing leaks. At Welping, quality starts at the source.

In pipe engineering, there are many standards and terms used to describe pipe sizes. Here are some of the most commonly used terms:

A Comprehensive Guide to Larger Diameter Pipes: Applications, Benefits, and Industry Insights

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

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

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.

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