Galvanizing steel pipes is also known as ‘rust treating’. Ingalvanizing refers to the chemical process of turning an alloy into a hard, durable substance called ‘manganese’ by subjecting it to an electrolysis process. Manganese is actually a molybdenum metal that has many beneficial properties, including tensile strength. Therefore it was found very useful as a remedy for rusting in pipes.
A 500 mm Square Steel Pipe – Square & Rectangle Steel TubingASTM A500 structural piping is mainly welded circular & square steel tubes formed with high-carbon steels, welded together and then welded again. Welded piping is known as ‘flat steel pipes’. Longitudinal butt joints of rectangular tubing shall be welded over its thickness to insure the structural design strength of this steel tubing. During welding, the flat steel tube’s outside diameter shall be slightly greater than the inside diameter of the tube to create a mild convexity. This mild convexity provides increased rigidity at the joints allowing for much stronger connection.
Hollow Section Galvanized Steel Tube A hollow section of a steel pipe is formed by welding in the hollow section of the pipe a thin gauge steel tube. This is known as a cold-formed square or round steel tube. The purpose of using a hollow section is to decrease the weight of the pipe and the section becomes hollow, therefore increasing the length of the pipe. Since the weight of the pipe is decreased, the amount of heating required to weld the section decreases.
Galvanized Steel Tubular These are used in piping where there is a need to increase the length of the line because of a narrow spot. For this the galvanized steel tubing is formed into a long slender strip similar to the shape of a bar. It is then welded to a larger flat section of stainless steel to make a hollow section. This hollow section carries a threaded insert that forms a portion of the inner part of a hollow square pipe. These tubes are commonly used for refrigeration lines and to carry refrigerant gas.
Square Steel Pipe Prices Galvanized pipe has a low price but it has many advantages. It is less prone to corrosion, it has a higher melting point than other metals, it is more ductile and stronger than other metals which increases its strength. Moreover the price of galvanized tubing is relatively low as compared to other metal pipes such as the a500 structural pipe. It is because of these benefits that Square steel pipe manufacturers sell this product at a lower price than other pipe manufacturers.
Square steel pipe is known for its ability to resist corrosion. It is also able to carry a considerable amount of heat. These properties result in its ability to form hollow sections in the pipes. The ability to form hollow sections and the high melting point of stainless steel make it a popular pipe for use in piping applications.
