Galvanizing is a surface treatment technique in which a layer of zinc is applied to the surface of metals, alloys, or other materials to provide aesthetic appeal and to prevent rusting. The function of galvanizing is to prevent rusting of steel, which is easily rusted in the natural atmosphere. While zinc does not change easily in dry air, it forms a dense protective film of zinc carbonate on the surface in humid environments, which protects the steel.
Zinc is stable in dry air and does not easily change color. In water and humid atmosphere, it acts with oxygen or carbon dioxide to produce oxide or alkaline zinc carbonate film, which can prevent zinc from continuing to be oxidized. Zinc is very susceptible to corrosion in acids, alkalis, and sulfides, so galvanized layers are generally passivated. In chromic acid or in chromate solution after passivation, due to the formation of the passivation film is not easy with the role of humid air, its anti-corrosion ability is greatly strengthened. Galvanized low cost, easy processing, suitable for use in atmospheric conditions and other good environment.
Galvanized pipe coupling has thicker dense pure zinc layer covering the exterior of the joints to avoid touching the substrate with any corrosive solution, maintaining the substrate from corrosion. In the general atmosphere, the appearance of the zinc layer constitutes a very thin and dense zinc oxide layer appearance, it is difficult to dissolve in water, so the joints play a certain maintenance effect. If zinc oxide and other components of the atmosphere to generate insoluble zinc salt, the anti-corrosion effect is better.
Galvanized pipe couplings have excellent mechanical properties, including strength, toughness, and wear resistance. These properties enable galvanized pipe couplings to withstand greater pressure and impact, ensuring the stability and safety of the piping system. In addition, the abrasion resistance of galvanized pipe couplings enables them to maintain good performance in harsh working environments.
Galvanized pipe couplings also offer certain advantages in terms of environmental protection and sustainability. Firstly, zinc is a recyclable material, so galvanized pipe couplings can be recycled after use, reducing environmental pollution. Secondly, the long life and low maintenance costs of galvanized pipe couplings are also in line with the concept of sustainable development, which helps to reduce the operating costs of enterprises and their impact on the environment.
As a leading name in the industry, Tiancheng has mastered the art of providing galvanised pipe connectors and couplings that transcend conventional expectations. The galvanization process ensures that each component, whether it's a galvanized press fitting or a galvanized slip coupling, is fortified against corrosion and rust, contributing to the enduring performance of piping systems.
