LSAW steel pipe (Longitudinally Submerged Arc Welding abbreviated as LSAW) is a professional expression term for LSAW steel pipe. It uses a single medium and thick plate as the raw material, and the steel plate is pressed (rolled) into a tube blank in a mold or a forming machine. The pipe is produced by submerged arc welding and expanded diameter.UOE 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.JCOE LSAW pipe forming process:Forming: After several steps of stamping on the JCO forming machine, first half of the steel plate is pressed into a "J" shape, then the other half of the steel plate is pressed into a "J" to form a "C" shape, and finally pressurized from the middle to form An open "O"-shaped tube blank is formed.

Steel pipes, also known as steel tubes, are hollow cylindrical constructions manufactured from steel, a strong and flexible material noted for its durability and resistance to corrosion. There are different kinds of steel pipes available, including seamless pipes and welded pipes. Seamless pipes are manufactured without any welding joints, while welded pipes are constructed by joining two pieces of steel using welding techniques.

Steel pipes come in many forms and sizes. Seamless pipes are a non-welded option produced from hollowed-out steel billets. When it comes to welded steel pipes, there are three options: ERW, LSAW and SSAW.ERW pipes are made from electric resistance welded steel plates. LSAW pipes are made from longitudinally submerged arc welded steel plates. SSAW pipes are made from spiral submerged arc welded steel plates.Steel pipes are typically used in the oil and gas industry for exploration and extraction (upstream), the transmission of fluids like oil, gas and slurries (midstream) and oil refinement into derivative products (downstream). They are also used for agricultural irrigation, urban construction and more.Let’s take a closer look at each type of pipe, comparing their differences and how to make an order with the right description.

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.

Stainless steel is a corrosion-resistant alloy of iron, chromium, and often other elements such as nickel, molybdenum, or manganese. It’s called “stainless” because it resists staining and corrosion, making it a popular choice for a wide range of applications where durability and resistance to environmental factors are important.Stainless steel resists tarnishing and rust because of the elements contained within: iron, chromium, silicon, carbon, nitrogen, and manganese. It must be composed of at least 10.5% chromium and at most 1.2% carbon to be recognised as stainless steel.

Will a magnet stick to stainless steel? It depends on what type of stainless you’re using. Some steels are only weakly magnetic, and some are not magnetic at all. Austenitic stainless steels like 304 or 316 stainless are good examples of this.A ferritic stainless like 430 stainless steel, on the other hand, is ferromagnetic. Magnets stick to it. You might see magnetic forces that are 5-20% weaker compared to low carbon steel.

Stainless steel is 100 percent recyclable and has a recovery rate close to 100 percent. It is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction.

I was wishy-washy about putting stainless steel in our kitchen, because I’m actually a fan of white appliances. Gasp! It is true. I had to be convinced to go stainless steel. One thing that made me super nervous were the greasy fingerprints, which I noticed on all the display models at the store. (Maybe I should email this post to those stores?)There are three little ones running around this house, which means there are thirty fingers actively leaving their marks all over my home and stainless steel appliances. It will be very soon when baby is adding his ten fingerprints to the mix. Children live here and I don’t mind being reminded. Still, it is nice to clean the appliances in the kitchen and give the children a clean slate for their finger smudge art. Right? And my cleaner costs me less than 25 cents for two full bottles. And it is organic, non-toxic, fume-free and completely safe for me and my kids. In fact, I use the same cleaner to wash my fruits and vegetables. Shut the front door! Yep.

As an alloy, stainless steel is made up of a combination of metals with the balance being iron but the main alloying element being Chromium. Stainless steel resists tarnishing and rust because of the elements contained within: iron, chromium, silicon, carbon, nitrogen, and manganese. It must be composed of at least 10.5% chromium and at most 1.2% carbon to be recognised as stainless steel.Chromium (combined with nickel) is the component that gives stainless steel its corrosion resistance. While stainless steel is frequently called stainless, it is not really stainless, because the chromium builds up on its surface making it able to withstand abuse much longer than regular steel without chromium. Passivation is the process of applying chromium to stainless steel to keep the shiny, silver finish.
