1.FBE

Single Layer FBE coating pipes are applied to transfer water,natural gas, etc. The working temperature is -30℃ to 100℃. They are isused all over the world.

External FBE pipes are easy operation, no no pollution themo-stability, and high mechanical strength on bending and impacting.

Internal FBE can reduce the secondary pollution of the transport medium, extend the steel pipeline's service life.

3.2LPE/3LPE

Buried steel pipes with 2PE/3PE coating are used for the transmission of water, oil, gas and other media, the working temperature is 50℃-70℃, it has good performance of anti-corrosive, low water-absorption rate, high mechanical strength.The material is as follows 3PE:

1. Epoxy coating (FBE) – chemical resistance and cathodic disbondment resistance;

2. Adhesive - to ensure the affinity between the bottom layer and the surface layer;

3. Polyethylene (PE) – for mechanical protection and anti-corrosion.

4.3LPP

The same as 3LPE, the buried steel pipe with 3LPP coating is used for the transportation of water, oil, gas and other media. Unlike 3LPE, its third layer is polypropylene. And it has more advantages than 3LPE in the following aspects, and of course the price will be higher:

1. High applicable temperature: the working temperature of the coating can reach 110℃~150℃.

2. Long service life of 3PP at high temperature: DIN30678 says that the life is 30 years at 80°C, 15 years at 90°C, and 8 years at 100°C. (3PE when the temperature is higher than 80℃, the PE layer will soften)

3. Good peel strength and indentation hardness at high temperature

4. The impact resistance is suitable for a wide range of temperatures

5.Hot dipped Galvanized

Hot dipped galvanizing is the process of coating to protect steel from rusty corrosion.

The hot-dip galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. It is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot dip coating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion, strong corrosion resistance, and long service life.

6.Painted

The main colors of spray paint are Black, Red, and Varnish and more. Customers can customize the color according to different use ranges, such as yellow for gas pipelines and red for fire pipelines.

Black Painted

There are three treatment methods for the surface of the fire pipe.

The first epoxy coating: Red (Ral3000), Reddish-brown (Ral 3009), Grey (Ral 7012);

Second spray paint: Black (Ral 9005), Red (Ral 3000), Reddish-Brown (Ral 3009), Grey (Ral 7012);

The third type of Hot Dipped Galvanizing, the thickness of the zinc layer is 50-55 microns/㎡.

7.Oiling

Oiling is designed to prevent rusting of steel products. Under the usual conditions of packaging, transportation, handling and storage, the supplier shall guarantee that the surface of the steel pipe will not rust within * months from the date of completion of manufacture. The thicker the oil film, the stronger the anti-rust ability, and the thickness is determined according to the anti-rust time.

Oil products, generally used mineral oil type anti-rust oil (solvent type), after a period of time, it will naturally become muddy and clean. The oil film can also be removed with an alkaline aqueous solution.
