Spiral steel pipe is a spiral seam steel pipe, which is made of strip coil plate as raw material, often formed by warm extrusion, and welded by automatic double-wire and double-side submerged arc welding process. Adopting advanced double-sided submerged arc welding technology, the welding can be achieved in the best position, not easy to appear the wrong edge, welding deviation and penetration defects, easy to control the welding quality.
According to the American Iron and Steel Institute (AISI), ferrous material is designated as carbon steel when its core makeup is specified to include no more than 1.65 percent manganese, 0.60 percent silicon and 0.60 percent copper and when no minimum content is specified for other alloying elements. Carbon steel pipe enjoys wide use across many industries due to its strength and ease of workability. Because it contains relatively few alloying elements and in low concentrations, carbon steel pipe is relatively inexpensive.

Alloy steels are what they sound like: Steels that include specified amounts of alloying elements. Generally, alloying elements make steels stronger and more resistant to impact or stress. While the most common alloying elements include nickel, chromium, molybdenum, manganese, silicon and copper, many others are used in the production of steel. High-alloy types of steel are favored in the piping industry for service in extreme conditions, whether it be in hot or cold conditions or subject to rough use. Thatâ??s because the combination of chemistry and proper heat treating can yield strong yet ductile pipe that can take a beating. The oil & gas and power generation industries often favor alloy pipe due to its toughness.

ASTM A120 black steel pipe is uncoated steel, also known as black steel. The industry uses black pipe as a term to distinguish plain mild steel pipe from galvanized steel pipe. Therefore, black pipe generally refers to any ungalvanized steel pipe.The dark color comes from iron oxide that forms on its surface during manufacturing. When the steel pipe is forged, a black oxide skin is formed on its surface, giving it the finish seen on this type of pipe. Black steel pipe is sometimes called black pipe, black iron pipe, industrial pipe. As mentioned earlier, welding is possible because the product is made of mild steel. But because of the various names used, some people mistook the black pipe for iron, mistakenly believing that welding was difficult.

Galvanized steel pipe mainly used in transmission of coal gas, steam. It was used as water pipe, but after several years past, there were many rust in the pipe, and water get yellow color for carrying iron oxide. The water not only polluted dishes or other sanitary ware, but also carrying bacteria produced in the internal surface which not smooth . As a result of the corrosion, the water contains heavy metal element is too much and is harmful to peopleâ??s health. For this reason, developed countries gradually� banned it using as water pipe since 1960s.

Cold galvanized is electric galvanized, galvanized amount is very little, only 10-50g/m2, its own corrosion resistance is much different than hot galvanized steel pipe. Regular galvanized steel pipe manufacturers, in order to ensure quality, most do not use galvanized (cold plating).

The molten metal reacts with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanized steel pipe is first pickling, in order to remove iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing steel pipe has the advantages of uniform coating, strong adhesion and long service life. Most of the processes in north China are zinc plating with direct coil pipe.

It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. Cold drawing, welding, extrusion and hot rolling are the methods of producing special-shaped tubes. Compared with the circular tube, the special-shaped tube generally has larger moment of inertia and section modulus, and has greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.
Line pipe is a type of pipe that is manufactured from high strength carbon steel. It is typically made according to metallurgical specifications that were developed by the American Petroleum Institute (API). Line pipe can be used to build pipelines that transport a variety of resources including natural gas, oil, petroleum, and water. This pipe is available in a variety of diameters ranging from 2 inches to 48 inches. Line pipe can include either seamless or welded carbon steel or stainless steel piping. Because line pipe needs to withstand high pressures, there are important tests done on line pipe to ensure it meets all of the requirements of steel chemistry, strength, toughness, and dimensional characteristics. Using line pipe that meets the set criteria will ensure safe and reliable pipeline service.

The square pipe is a hollow square section light thin-walled steel pipe. It is a section steel with a square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then welded by high-frequency welding. It has good comprehensive mechanical properties, weldability, cold and hot work ability and corrosion resistance, and has good low temperature toughness. Square pipe and rectangular pipe is equal and unequal length of the steel pipe. Is made of steel after the process of rolling. Generally the strip is unpacked, flattened, curled, welded to form a round pipe, and then rolled into a square pipe and then cut into the required length.
