At the coming moment, Tube China will be held in Shanghai China from 14th -16th June 2023, This is the first large-scale pipe fair after 3 years of COVID-19, and it will be a good business gathering.  

The 10th China International Tube Exhibition (Tube China) was successfully concluded in Shanghai New International Expo Center on June 16 with the care and support of all walks of people.

Steel tube (and Steel Pipe) has evolved over history. Specifically, metal tube has been around since around 3000 BC. In fact, Egyptians made the first metal pipe from copper.As Early as 2500 BC Chinese used bamboo pipe as a way to transport gasAs early as 2500 BC, Chinese used bamboo pipe as a way to transport natural gas to light Peking, their capital. Rome and Persia created aqueducts to bring water to city centers for bathing, washing and drinking.Furthermore, pipe (or tubing) is made with many different materials and methods. Hollowed stone, fired clay, bamboo, palm, redwood, lead, bronze, copper, and rubber are just some of the materials that makeup tubing.In the mid-1800’s the modern steel industry was bolstered with the Bessemer process. The Bessemer process represented the first inexpensive method for mass production of steel pipe. Subsequently, seamless tube was born in 1895. Quickly followed by manufacturing of auto, bicycle, and machinery for oil production which began in full force.

Four different welding processes are typically used for making tube. Since there is no filler metal in these welds, the welds are at least as strong as the parent metals.High Frequency (HF) Welding. Today, most mild steel and aluminum tube is welded with HF welders, which are also suitable for 400 series stainless and even 300 series if the tubing is for decorative use.Nearly 95 percent of the HF welders sold are solid-state, using transistors to generate the alternating frequency current. Research has been undertaken to weld products less than 1/4 inch in diameter and to extend the ability of the welder to produce a pressure-quality weld on 300 stainless steel at high line speeds.

Abbreviated ERW, this is a format that signals a specific welding process – actually two processes, spot and seam welding. This process involves several specific steps where the steel is unwound and trimmed, then passed through rollers to cold-form the steel into the proper shape (circular, square or rectangular).From here, the edges are forced together into a butt joint, then welded at a very high temperature to form a flash weld. Once the weld is tested, the tube passes through various sizing rolls to achieve the proper size, and then the length is cut. The materials used here will generally be available in both hot-rolled and cold-rolled formats.

Floating/Drawing process of pulling a metal bar, rod, or wire through the whole of a die to alter its finish, shape, size, and/or mechanical properties. The tube drawing technique reduces the outer diameter, inner diameter, and wall thickness of the tube. The integrity of the surface of the tube is maintained, ideal for stainless steel tubes. 

In the nineteenth century, rolling mill technology was the only technique used to manufacture stainless tubes and pipes for industrial purpose. This rolling technique involved long procedures.  The rolled strips of sheet were formed into a circular cross section with the help of funnel rolls. The lap welding was then done on these rolled strips through the forge welding process.Thankfully with the advent of development and technology, various processes came into existence for the manufacturing of stainless tubes and pipes in India. Now-a-days, stainless steel pipes and tubes are manufactured with continuous tube mill using multitorch tungsten Inert gas. The filler metal or forge welding process is not used in this technique.

Carbon steel tube is an economic steel, the product of steel and its variety of specifications are extremely wide, and its performance requirements are also varied.

Since I recently learned how to weld, I’ve been experimenting with different methods of cutting metal. I typically use an angle grinder, but with so many different tools on the market I thought I would start experimenting with other options. Today I’m going to show you how I cut tube steel using my new Makita Portable Compact Band Saw.

Stainless steel is one of the most popular materials used for custom tube bending due to its excellent strength and superior resistance to corrosion. It is the ideal choice for a variety tube and pipe components, including OEM instruments and machinery, manifolds and hydraulic fluid supply lines, cooling coils, water nozzles, and more.

Aluminum Tube bending is a common forming process that we as metal manufacturers practice. Additionally, it happens to be the main operation when it comes to tubing and piping. There are, however, a few factors to consider before carrying out tube bending. Here is an outline of what we are going to cover.

ERW, or Electric Resistance Welded steel, refers to the manufacturing method whereby Round E.R.W Steel Tube, or Electric Resistance Welded Steel Pipe has its steel edges melted and welded to form a consistent cylindrical shape. Heat and pressure are combined to join the steel sheet to give you a very lightweight and easy to work with tubing for an array of engineering and construction requirements from fencing to scaffolding. It can even be used in domestic or commercial settings for a vast array of possibilities.The end product exists between welded steel pipes and seamless materials and is therefore smooth and more consistent in surface texture without an obvious weld seam. You'll get a really consistent edge that's easily formed, durable and easy to work, weld, cut to size and drill.

Oil casing is a non-circulating steel pipe component used to stabilize the wellbore structure of oil and gas wells. Its core role is to ensure the stability of the wellbore during drilling operations and the long-term effective operation of the entire wellbore after completion.

OCTG casing is an essential product for petroleum production. It connects two casing pipes with threaded couplings to form a casing string of several thousand meters. For casing couplings, thread processing is one of the key points. Therefore, the quality of the coupling is related to whether the entire casing is safe and reliable. Therefore, proper control of deformation and roundness during the processing of oil and casing couplings can make threads more reliable and fundamentally solve thread quality problems.

Hollow seaction refer to metal materials with a hollow cross-section. Compared with solid profiles, hollow sections are lighter, but have better performance in terms of load-bearing capacity and high strength. Rec-tube and square tube are common HSS. According to the raw materials, it has two different types: carbon and stainless steel.

Cold-drawn seamless tube is a kind of seamless pipe. Seamless pipe is a long steel material with a hollow cross-section and no seams around it. Compared with welded steel pipes, cold-drawn seamless pipes are a type of steel processed through a series of cold drawing, cold bending and other technologies in a normal temperature environment.

Octg casing strength refers to the ability of the octg casing material to resist damage by external forces. In petroleum engineering, octg casing is used to withstand underground pressure, prevent wellbore collapse, isolate formations and other important functions. Its strength is crucial to the stability and safe operation of the wellbore.

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.
