Omschrijving:

Galvanized steel pipe is divided into hot galvanized steel pipe and cold galvanized steel pipe

Thermisch verzinkte buis

The molten metal is reacted with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. Most of the northern processes use galvanized strips to directly coil the zinc

Koud gegalvaniseerde buis

Koudverzinken is elektrolytisch verzinken. De hoeveelheid galvanisatie is zeer klein, slechts 10-50 g/m2, en de corrosieweerstand is veel slechter dan die van thermisch verzinkte buizen. Reguliere fabrikanten van gegalvaniseerde buizen maken, om de kwaliteit te garanderen, meestal geen gebruik van elektrolytisch verzinken (koudplating). Alleen kleine bedrijven met kleine apparatuur en oude apparatuur gebruiken elektrolytisch verzinkt staal, uiteraard zijn hun prijzen relatief goedkoper. In nieuwbouwwoningen is het gebruik van koudgegalvaniseerde stalen buizen als watertoevoerleidingen verboden.

Verschil thermisch verzinken en koud verzinken

Thermisch verzinkproces:

Werkstuk ontvetten → wassen → beitsen → wassen → drogen oplosmiddeldompelen vloeien voorverwarmd thermisch verzinken → koelen → afwerken → spoelen → drogen → passivatietest

Koudgegalvaniseerd proces:

Chemisch ontvetten → wassen → warm water warm water elektrolyse ontvetten → wassen → wassen → sterk corrosieve gegalvaniseerde ijzerlegering → wassen → wassen → licht → → wassen → drogen passivatie

De voordelen van gegalvaniseerde buizen volgen hieronder:

Firstly, galvanized pipe after being hot dip galvanized surface can be protected, and inside the cavity of the pipe or any other coating the corner is difficult to enter, deepen the zinc can easily cover to the top, make whole galvanized pipe can be protected.

Second, after being galvanized pipe galvanized its impact resistance and anti-wear properties are very good, because the zinc coating hardness values larger than the hardness of steel, and therefore the impact resistance of hot-dip galvanized after and abrasion resistance is quite good. Furthermore galvanized biggest advantage is in the corner of the zinc layer will be relatively thick and good toughness and abrasion resistance, while other coatings are often in this corner of the thinnest most difficult construction, and therefore are vulnerable injury.

Beschrijving:

Galvanized welded pipe refers to a type of steel pipe that has been coated with a layer of zinc through a process called galvanization.

The galvanization process involves immersing the steel pipe in a bath of molten zinc, which forms a protective layer on the surface of the pipe.

The purpose of galvanizing welded pipes is to provide corrosion resistance and extend the lifespan of the pipe. The zinc coating acts as a barrier between the steel and the surrounding environment, protecting the pipe from rust and other forms of corrosion.

This makes galvanized welded pipes suitable for various applications, especially in industries where exposure to moisture or corrosive substances is common.

Enkele belangrijke voordelen van gegalvaniseerde gelaste buizen zijn onder meer:

1. Corrosion resistance: The zinc coating provides excellent corrosion resistance, making galvanized pipes suitable for outdoor and underground applications.

2. Durability: The combination of steel and zinc coating enhances the strength and durability of the pipe, allowing it to

bestand tegen zware omstandigheden en intensief gebruik.

3. Cost-effectiveness: Galvanized welded pipes are generally more affordable compared to other corrosion-resistant alternatives,making them a cost-effective choice for various projects.

4. Easy installation: Galvanized welded pipes are relatively easy to install due to their standardized sizes and compatibility

met veelgebruikte fittingen en connectoren.

5. Versatility: Galvanized welded pipes are available in various sizes and thicknesses, making them suitable for a wide range of applications, including plumbing, construction, agriculture, and industrial projects.

It is important to note that galvanized welded pipes have limitations. Over time, the zinc coating may degrade or wear off,

especially in highly corrosive environments. Therefore, regular inspection and maintenance are necessary to ensure the continued protection of the pipe.

Additionally, when working with galvanized welded pipes, it is important to take proper safety precautions, such as using

appropriate personal protective equipment and ensuring proper ventilation, as the galvanization process can release fumes that may be harmful if inhaled.
