Difference Between Stainless and ERW Stainless Steel Pipe

Image
  In this article, we will have a brief look at some of the differences between seamless and ERW that can have a significant effect on your application and the economics of the system. The manufacturing process for Electric Resistance Welding (ERW) pipe involves rolling metal and then welding it longitudinally across its entire length, resulting in an ERW pipe. The seamless pipe is manufactured by extruding the metal to the desired length, as compared to the ERW pipe, which is welded at the cross-section the entire length of its length, while the seamless pipe does not have any joints at the cross-section at all throughout its length.   The seamless pipe is manufactured from solid round billets, has no joints or welding and no welding process is involved in its manufacturing. In sizes from 1/8 inch to 26 inch outside diameter, the seamless pipes are finished according to the specifications of dimension and wall thickness. High-pressure applications such as hydrocarbon industries

What’s the Difference Between Steel Pipe and Steel Tube

  A hollow section of steel with a round cross-section has been manufactured in the United States since the early 1800s. It is made for the transportation of a wide variety of products, including fluids, gas, pellets, powders, and more. There are many uses for steel pipes, including underground transportation of water and gas, construction to protect electrical wires, and even the transport of liquids and gases. Steel pipes are not only strong, but they also can be lightweight. In addition to this, they are also used for making parts for automobiles, refrigeration units, heating and plumbing systems, flagpoles, and street lamps, just to name a few. This makes them ideal for bicycle frames and other products. The most important dimension for a pipe is the outer diameter (OD) along with the wall thickness (WT). By subtracting the outer diameter from the wall thickness (WT), the inside diameter (ID) of a pipe is determined, and the amount of liquid it can hold. When we talk about pipe i

Difference Between 316 and 302 Pipes

What is stainless steel? As with all steels, stainless steel contains the same basic iron and carbon composition as other steels, but stainless steel also contains a healthy dose of chromium that gives this alloy its salt corrosion resistance fame. The term stainless steel describes a group of materials with a slightly different alloy composition, which is responsible for the slightly different physical characteristics of each of these materials. Chromium must be at least 10.5 percent in stainless steel. It may also contain other alloying elements that can be much higher in concentration, such as molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous, or selenium, depending on the grade. Common stainless steels Most stainless steels are made from 302 and 316 grade stainless steel. The main difference between the two grades is the addition of molybdenum, which enhances corrosion resistance very significantly in salt- and chloride-exposed environments. 302 Stai

Difference Between 316L and 304L Pipes

  What is Stainless Steel? Iron is one of the softest elements in the universe. Adding up to 2% of carbon to steel, which is now known as steel, gives it incredible strength, hardness, and mechanical properties, all of which are a result of its carbon content. A lot of people use steel due to the abundance of iron and its easy and cheap availability, as well as the fact that steel is also very flexible. However, steel also has a weak spot, which is found in the iron that is used in steel products. Oxidation, or rusting, is a natural process that occurs to metal over time. As a result of oxidation, rust forms.   A chemical reaction occurs when an element is combined with oxygen, resulting in oxidation and corrosion, which takes place on the surface of the metal when oxygen is combined with all elements innature. The corrosion process forms a very thin layer on the surface of the element, which, once this layer has formed, acts as a protective layer, preventing the material from c

304 Seamless vs Welded pipes

  There are many methods of making seamless steel pipe. One of them is the use of billet steel. As the steel is heated and pushed or pulled over a form, it is molded into a hollow tube. Seamless pipes can come in many different sizes and schedules. Nevertheless, there is no manufacturing of large diameter seamless pipes. However, seamless pipes are commonly used as pipe fittings, such as bends, elbows, and tees. Since a seamless stainless steel tubing has no seams, it is able to withstand high temperatures equally, whereas a pipe with seams is generally weak at the spot of welding. As a result, the seamless steel tube can withstand high pressures equally at its entire diameter. There are two types of seamless steel pipe, namely, the solid steel pipe and the hollow tube. The seamless steel pipe is an integral tube with one end attached to another, without any welding joints. The seamless pipe has threads at either end of it, but they can also be threaded to both ends of a hollow tube

Seamless Vs Welded Stainless Steel tubing

  What Is Seamless Stainless Steel Tubing and What Are the Advantages? It is necessary to have a mechanism in order to force a hole into a billet in order to make seamless tubing. Seamless tubing does not have a longitudinal weld seam. The seamless meaning pipe is manufactured without welding at any stage. When welding pipe, no filler is added during the welding process. As a result, rotary piercing and rolling are considered to be the most popular method today for manufacturing seamless tubing. It is the process of heating, piercing, and working a steel round bar that has been conditioned. As the tube is forced to flow around a piercer point, it creates a hollow billet which is supported by a mandrel or plug, while the billet roller is extended. Additional rolling on the outside diameter of the steel tube is required to size it.    In addition to this, seamless tubing can withstand a pressure up to 20% higher than welded tubing of the same material and size due to the absence o

What is Welded Steel Pipe

  A welded steel pipe is constructed from a flat steel plate or a flat steel strip, and the manufacturing process results in a seam on the pipe’s surface. For welded steel pipes, the steel plate or strip must be bent and then welded into either a circular, traditional pipe shape or a square shape as part of the manufacturing process. There are three types of welded steel pipes: LSAW pipe, SSAW pipe, and ERW pipe. Each type is categorized based on the way in which the pipe is welded. There are two types of welding techniques used in pipes, LSAW and SSAW. LSAW pipes are longitudinally welded, while SSAW pipes are spirally welded. ERW pipes are electric resistance welded, which results in a seam that runs parallel to the pipe body.   There are many types of welded steel pipe, but all of them are quick and easy to produce. Moreover, they tend to be cheaper than their alternatives, such as seamless steel pipe, which occupies more space and costs you more money. Overall, welded stainless s

316 Stainless Steel Pipe vs 316L Seamless Pipe

  What is 316 Stainless Steel Pipe? It is a steel tube made of molybdenum, chromium, and nickel alloy with molybdenum added to it. The material is highly wear-resistant and corrosion-resistant compared to the ordinary 304 steel material, due to its high wear-and-tear resistance, strength, and corrosion resistance. A stainless steel tube of the gra 316, which is high-quality stainless steel, is ideal for applications requiring high strength and corrosion resistance. Stainless steel 316 is the world’s second most widely used grade in the world. Because of its resistance to corrosion and stress cracking caused by chloride ions in chloride ion networks, stainless steel 316 tubings are employed in a wide range of applications in some of the most important industries such as food processing, marine industry, seawater processing, nuclear power plants, heat exchangers, and boilers. Because of this, this material can survive in environments with a high concentration of chloride ions. Benefi
