Types of Steel Pipe

Seamless Steel Pipe: A seamless pipe is formed by piercing a solid, near-molten, steel rod, called a billet, with a mandrel to produce a pipe that has no seams or joints.

Galvanized Steel Pipe: Galvanized steel pipe is a kind of pipe that has been electrochemically treated and coated with a layer of zinc on the surface of the steel pipe, which mainly increases the corrosion resistance of the pipe. Therefore, the material of the galvanized pipe is carbon steel, stainless steel and other metal materials.

Square Tube: Square tube is an extruded product that is widely used for all types of fabrication projects where lightweight and corrosion resistance is a primary concern. Square tube has square corners inside and outside, with no weld seam.

Spiral Steel Pipe: Spiral steel pipe (SSAW), is a kind of tubular steel made of low carbon steel or low alloy steel through spiral welding process. Spiral pipe has the characteristics of high strength, good bearing capacity and excellent welding performance, so it has a wide range of applications in infrastructure construction, industrial production and other fields.

Stainless Steel Pipe: Stainless steel pipe is a kind of hollow long round steel. It is mainly used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components.

Surface Treatment of Steel Pipe

In order to correctly understand surface pretreatment, we should first have a complete understanding of the factors affecting its process. The spraying method, abrasive and carrier for conveying abrasive are selected according to the characteristics, type and size of the workpiece to be sprayed, as well as the expected purpose after spraying. Because there are many influencing factors involved, it should be very cautious.

Through the cost analysis of the covering layer, the general surface treatment cost accounts for about 50%. The coating of the drag-reducing inner coating is thin, the number of coatings is small, and the amount of coating is small. Therefore, the cost of surface treatment is higher, about 70%. Therefore, in the process design and construction of the drag-reducing inner coating, special attention should be paid to the quality of surface pretreatment.

Production Process

The main production processes are: pipe billet preparation and inspection → pipe billet heating → piercing → rolling → reheating of rough pipes → sizing (reduction) → heat treatment → straightening of finished pipes → finishing → inspection (non-destructive, physical, and on-site inspection) → storage.

Applications of Steel Pipe

Automotive exhaust pipes
Steel pipes can be designed to fit automotive exhaust systems. Steel pipes are hard-wearing, meaning they're able to retain their shape and function for the car's exhaust system.

Condenser tubes
Condenser tubes are found in many HVAC systems, pressure vessels, or turbines and they're typically used for heat exchange. Since steel pipes are highly resistant to corrosion, they make another good choice as condenser tubing material.

Irrigation systems
Another popular use of steel pipes can be found in agriculture, particularly in irrigation systems. Steel pipes can easily serve as a vessel to carry the water that is consistently flowed in irrigation systems. Due to their sturdiness, they require very little maintenance. Although the initial cost of steel piping in irrigation can be expensive, this will eventually pay off and present cost-effective options.

Farm gates
Steel pipes can be fashioned and designed to become farm gates for the agricultural sector. They can come as a pre-engineered steel pipe framework, or as individual steel pipes that can be strongly welded together to form the enclosure. Ultimately, they offer a stable structure that won't easily deform in cases of high-impact caused by movement.

Residential gates
Aside from farm gates, steel pipes can also be machined into residential gates for any kind of contemporary home. Steel pipes not only have functional but also design aspects that any homeowner may want to take advantage of. Steel pipes can also be galvanized to improve upon their properties. Galvanized steel pipes can provide your gates with a shinier and more elegant finish that you otherwise wouldn't find with other types of structures.

Electrical conduits
Steel pipes used as conduits are typically referred to as rigid metal conduit. These conduits have undergone the galvanizing process to create a corrosion-resistant finish, instead of having to use stainless steel altogether. RMC can come in various lengths, depending on the length of wiring to be enclosed. Steel RMC offers great protection against electrical wires or other faulty wiring situations.

Packaging & Shipping
