Name: Durable Galvanized Round Pipes for Industrial & Infrastructure Projects
Brand: Zhongtong Dingxing

Description

Material and Common Specifications
Main material: Q235B carbon structural steel, with stable properties, excellent welding performance, high toughness and excellent cost-effectiveness. It is suitable for most water and air passage, and support structures.
Common specifications: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100, DN125, DN150 and other conventional engineering diameters. Wall thickness is divided into normal thickness and thickened thickness, and it can adapt to different low-pressure and medium-pressure working conditions.
Standard lengths: 6 meters per piece. It supports processing such as cutting, threading, beveling, head sealing, bending, and drilling. Customization for deep processing is available.
Core product advantages
Both internal and external anti-corrosion, resistant to rusting: The overall hot-dip galvanizing layer is dense and thick, effectively isolating air and moisture. The pipe wall is less prone to oxidation and rusting, eliminating problems such as pipe corrosion and blockage, yellowish water quality, and pipe perforation and leakage.
Good fluidity and low resistance: The inner wall is smooth and the galvanized layer is flat. The resistance of fluid transportation is small, and it is not prone to scaling. The water and air flow efficiency is high, and the pipes will not get clogged even after long-term use.
High strength and good toughness: The cylindrical structure distributes force evenly, has strong resistance to compression, bending and impact, and is not prone to deformation. It can be used as a conveying pipeline or as a structural support pipe material.
Convenient construction and strong adaptability: It can be threaded, sleeved, welded, or connected by flange. It is compatible with traditional plumbing installation methods. No additional painting for anti-corrosion is required on-site, significantly shortening the construction period.
Long service life and low maintenance cost: It can be used for several decades in indoor dry environments. In outdoor humid environments, its weather resistance is much better than that of black pipes. There is basically no need for rust removal or painting maintenance in the later stage.
