SSAW (Spiral Submerged Arc Welding) and LSAW (Longitudinal Submerged Arc Welding) are two different methods used for manufacturing welded steel pipes. Here's a comparison of the main differences between SSAW and LSAW pipes:Formation process:SSAW Pipe: The spiral welding process involves forming the steel strip into a spiral shape and then welding the edges using the submerged arc welding method.LSAW Pipe: The longitudinal welding process involves forming a straight, cylindrical pipe from a single steel plate or coil and then welding along the length of the pipe using the submerged arc welding technique.

We deal with a broad range of new projects for diverse application. One of the common misconceptions we encounter is the belief that all metals can be attracted by magnets or that all metals are magnetic. It is common knowledge that magnets don’t attract materials like wood, plastic, glass but, when it comes to metals, things are often less straightforward.Any material can be classified in terms of its magnetic behaviour when exposed to an external magnetic field. Although many think materials are either magnetic or non-magnetic, there are, in fact, five (5) categories of magnetic behaviour. But, for most of the elements of the periodic table, diamagnetism and paramagnetism are two of the most common types of magnetism (at room temperature). To properly define how a material responds to an applied magnetic field, we introduce a term called Magnetic Susceptibility, which is a value that indicates the degree of magnetization of a material in response to the applied magnetic field (i.e. it indicates to what extent the material gets magnetised by the applied field). Every material will have a Magnetic Susceptibility value. Relative magnetic permeability is another value that is used.

Stainless steel sinks continue to be a popular choice for the kitchen, despite the extra work required to keep the finish clean. Well, with this pantry-based routine, cleanup just got a little easier. Follow these simple steps to remove scratches, spots, and stains, and restore your sink’s original shine.

A handheld steel pipe cutter is a convenient solution for cutting steel pipes on any work site because it readily performs without electricity. A common steel pipe cutter can be seen in Figure 1. Although power tools, such as a circular saw, cut much faster, the need for electricity adds complexity to the task making a handheld pipe cutter suitable for applications away from a workshop or electricity.

Longitudinally Submerged Arc Welded Process FlowLSAW (Longitudinally Submerged Arc Welded Steel pipes) in leaflets plate as raw material, the steel plate in the mold or molding machine pressure (volume) into using double-sided submerged arc welding and flaring from production.The LSAW process of welded tube includes UOE and JCOEUOE LSAW pipe forming process:The three main forming processes of UOE LSAW steel pipe forming process include: steel plate pre-bending, U forming and O forming. Each process adopts a dedicated forming press to complete the three processes of pre-bending the edge of the steel plate, U forming and O forming in sequence to deform the steel plate into a circular tube.

Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. The first methods for producing steel pipe were introduced in the early 1800s, and they have steadily evolved into the modern processes we use today. Each year, millions of tons of steel pipe are produced. Its versatility makes it the most often used product produced by the steel industry. Steel pipes are found in a variety of places. Since they are strong, they are used underground for transporting water and gas throughout cities and towns. They are also employed in construction to protect electrical wires. While steel pipes are strong, they can also be lightweight. This makes them perfect for use in bicycle frame manufacture. Other places they find utility is in automobiles, refrigeration units, heating and plumbing systems, flagpoles, street lamps, and medicine to name a few. People have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists that diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. (Francis, 2009)Development of the modern day welded steel pipe can be traced back to the early 1800s.

Square pipe is a welded structural grade pipe available in Type A513 or A500 Grade B depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, fabrication and repair. Square tubes are widely used in industrial maintenance, farm implements, transportation equipment, truck beds, trailers, frames, etc.

Black welded steel tube refers to a welded pipe with a black surface. The "welded steel tube" indicates a steel pipe welded by steel plates or strips after being curled and formed, usually with a fixed length of 6 meters. The "black steel tube" is steel that is not galvanized and its color is caused by iron oxide on the surface.
