The importance of base tube

In the product system of plastic-coated steel pipes, the importance of the base pipe is often overlooked. However, in fact, the base pipe is the foundation of the entire pipe material performance. If the coating is likened to a "protective suit" worn by the steel pipe, then the base pipe itself is the "framework" providing strength and pressure-bearing capacity. Without high-quality base pipes, even the best coating cannot perform its intended function.

The Importance of Coating for Plastic-Coated Pipes

Plastic-coated pipes are a type of composite pipe that has a high molecular anti-corrosion coating applied to both the inner and outer walls of the pipe. They combine the mechanical strength of steel pipes with the corrosion resistance of plastics, and are widely used in municipal water supply and drainage, fire protection, chemical industries, etc.

What Are the Uses of Galvanized Steel Pipes?

Among the family of pipe materials, galvanized steel pipes have always held an irreplaceable position. They retain the high strength of ordinary steel pipes while obtaining excellent corrosion resistance through a surface galvanized layer. So, where exactly can this material be used? Today, let's talk about the common applications of galvanized steel pipes.

How to choose the right T-junction in a project?

When choosing a tee, the first thing to consider is its type. Equal diameter tees are used when the main pipe and branch pipe have the same diameter and flow rate; reducing tees are used when the branch pipe has a smaller diameter and lower flow rate. If conveying viscous media or used in drainage systems, a 45-degree angled tee is recommended to effectively reduce flow resistance.

Blog One: Oil Pipeline Infrastructure: The "Underground Blood Vessels" of Energy Giants

If oil is the "blood" of modern industry, then oil pipelines are the "blood vessels" that transport it. These steel giants buried underground are responsible for transporting oil from oil fields to refineries and from refineries to storage facilities, serving as the backbone of energy infrastructure.
