Allied flo-coat pipes

This type of galvanized steel pipes is cold formed, welded with high frequency and hot-dipped galvanization. It can be produced in accordance with ASTM A/AM and A/AM standards with a minimum productivity strength of 30,000 psi. Based on the pipes&#; diameter and size, their mechanical characteristics may have a minimum productivity strength of 50,000 psi and a minimum ductile strength of 55,000 psi.

The surface of the pipes can be composed of three corresponding coatings which are a lead-free zinc coating, a conversion coating protecting the pipes from white rust, and a plain organic polymer coating serving as a final protective layer for the pipes. After welding a zinc rich organic coating, the pipes&#; surface may be 100% covered with this kind of coating.

Pre-galvanized pipes

Pre-galvanized pipes are cold formed and welded with radio frequency pre-galvanized steel strip. The pre-galvanized steel has to be in correspondence with ASTM A446 standard. The zinc covering on the surface of the pipes should match the ASTM A525 Grade G90 and G120 requirements, and its weight ranges from 0.90 oz/sq ft (or 0.45 oz/sq ft each side) to 1.20 oz/sq ft (or 0.60 oz/sq ft each side).

Schedule 40 hot-dipped galvanized pipes

Schedule 40 hot-dipped galvanized pipes&#; outside diameter is determined by other specifications as for non-galvanized pipes. It is often hot formed and butt welded, or cold formed and radio frequency welded. The chemical qualities of these pipes are variable depending on the producing process. Their average productivity strength is approximately 30,000 psi.

Advantages and disadvantages of galvanized steel pipe

Advantages of galvanized steel pipe

Galvanized steel pipes have numerous advantages thanks to the protective zinc coating which makes the steel more advanced, strong and desirable in different situations.

Highly durable

The biggest advantage of galvanized steel pipe is its average long life expectancy which is up to 40 or 50 years in the countryside and remote areas. In severe conditions, damaged places or in urban areas, their lifespan can be more than 25 years. Moreover, the internal zinc-iron alloys are harder than the base steel, so the galvanized steel will have high resistance to erosion and shock. Also, the manufacturing of steel that is galvanized does not usually require any maintenance or preservation throughout their whole life.

Less expensive

The galvanization process does not usually cost as much as other popular methods of protecting pipes since galvanization is not so labor intensive while the other methods often require more blue-collar work. Therefore, galvanized steel pipes have quite lower initial costs. Additionally, as stated above, as they have a long lifespan, they need little or even no maintenance which helps to save a lot of time and money.

Easy to inspect and assemble

This is another big benefit of galvanized steel pipes. Leading galvanized steel pipes manufacturers and providers often provide customers with precise information on the products. The inspection process of galvanized coatings are easy and undemanding, you can totally examine them with the naked eye and test their thickness with straightforward and non-destructive methods.

Disadvantages of galvanized steel pipe

Interior corrosion

Although the protective zinc layer on the surface of the galvanized pipe can prevent oxidation for a certain amount of time, these pipes still unavoidably corrode because of continual exposure to moisture. The zinc erosion often occurs from the inside to the outside of the pipes, which will certainly limit the flow of water, thus lower the water pressure, and can ultimately lead to a leak or even broken pipe. Furthermore, the deterioration usually takes place unevenly leading to the uneven distribution of water in homes and buildings.

Water discoloration

Galvanized steel pipes corroding can release materials and lead which will leak into the water supply. This can ultimately result in water discoloration and contamination. You can detect this issue by looking at the color of the pipes.

Then an electric current joins the edges of the circular plates to create the end product.

This type of steel pipe is popularly applied in both domestic and commercial uses. These pipes can also be divided into sub-categories such as general pipes, galvanized pipes, metric pipes, roller pipes, automobile pipes.

Electric fusion welded (EFW) steel pipe

Electric fusion welded steel pipes can also be called continuous welded steel pipes. Their manufacturing process starts when coiled steel with proper thickness, width, and weight is made. A number of coils are then welded together to form a continuous steel strip. After that, the steel strip is heated to a certain temperature and given an oval shape. Finally, the edges of the steel strip are gathered into rolls which will then convert the welded pipes into particular dimensions.

Double submerged arc welded (DSAW) steel pipe

DSAW steel pipes are available in straight and spiral welded formats and utilized in a wide range of applications. The producing process of these pipes starts with the formation of steel plates into circular shapes which will be forged to create notches on the inside and outside of the seam. Afterward, the seam is welded by an arc welder submerged under fluctuation.

Besides these three types, there are also some other types of welded steel pipes as follows:

&#; High frequency Induction (HFI) welded pipes;

&#; Long submerged arc welded (LSAW) pipes;

&#; U-ing and O-ing (UOE) forming pipes;

&#; J-ing, C-ing, and O-ing (JCOE) pipes;

&#; Spiral submerged-arc welded (SSAW) pipes;

&#; Submerged arc welded (SAW) pipes;
