What Is Welded Pipe And What Are They Used For (SS 310 Welded Pipe)

What Is Welded Pipe And What Are They Used For (SS 310 Welded Pipe)

The welded pipe is made by forming flat products (strip, sheet, or plate) to the desired shape, in this case normally round. Once the desired shape is achieved, a high energy source is used to melt the metal locally at the weld joint. It is squeezed together and allowed to solidify, forming a weld bead. The high energy source can be an electric arc, a plasma arc, a laser beam, or even an electron beam.  The welded weld bead is usually a bit thicker than the adjacent base metal and needs to be changed to match the base metal thickness and to correct unwanted physical, chemical, and corrosion resistance attributes of the weld.

Welded pipe manufacturing

  • At the beginning of the ASTM A312 SS TP 310 Welded Pipes manufacturing process also known as slabs or billets are cast in a steel mill. Dependent on the external dimensions and wall thickness there are different methods of producing welded pipes: Electric Resistance Welding (ERW), Fusion Welding (EFW), and Double Submerged Arc Welding (DSAW). In the ERW and EFW manufacturing process welded pipes are formed by hot or cold rolling plate and welding the seam.
  • To keep the outside (O.D.) surface of a welded pipe smooth and uniform a cutting tool called scaring blade is used to remove the weld flash. Scaring from the inside (I.D.) welded flash is also possible. With heat-treating at the end of the manufacturing process, the weld zone of the steel pipe can be made less visible.
  •  Due to the weld seam, lower operating pressures are stated by ASME compared to seamless pipes. In generally welded pipes possess tighter dimensional tolerances than seamless pipes and are less costly if produced in the same quantities.

Application and Benefits of TITANIUM GR 2 Seamless Tubes

Titanium has a high tensile strength, and is very strong. Titanium is lighter in weight due to the presence of aluminum and is also very resistant to corrosion. An alloy obtained by combining iron and some other chemicals. The alloy is named as Titanium. The chemical elements that are present in the alloy are 6% of Aluminium, 4% of Vanadium, 0.25% of Iron, and 0.2% of Oxygen. All these chemicals and metals present in the alloy give it some of the best properties. Titanium can withstand extreme temperatures and conditions.

The thing with titanium is that it is expensive so this application is limited to military and medical and many other applications. This mixture has a solid solubility that changes dramatically with temperature, allowing it to undergo precipitation strengthening. This heat treatment process is carried out after the alloy has worked to its final shape, but allows for much easier fabrication of a high-strength product before it can be used. Alloys Titanium has four categories i.e. alpha alloys, near-alpha alloys, alpha and beta alloys, beta alloys and near-beta alloys. These are just categories and not grades, though the grades are different.

Titanium Grade 2 Tubes is suitable for many applications similar to Grade 1, but is very strong which allows it to be a metal for many applications. Grade 2 has good weldability, strength, ductility, and is used mostly in bar and sheet sizes.

A seamless tube is a type of tube that is commonly used by the world. Seamless tubes are relatively stronger than others and are much stronger. The process of manufacturing a seamless tube is long and complicated, but it all leads to the production of excellent tubes. The seamless Tubes is made using one piece of metal so it is much stronger and highly prevents and leakage and corrosion depends on the type of material used to manufacture the Tubes. The seamless Tubes comes in several size right from 50mm to 500mm or even 1 meter in diameter. The Tubes thickness plays a significant role as it avoids leakage.


The grades mentioned above are used for the following applications- Architecture, Power generation, Medical industry, Hydro-carbon processing, Marine industry, Exhaust pipe shrouds, Airframe skin, Desalination, Chemical processing, Chlorate manufacturing, Aerospace structures, Chemical processing, Medical industry, Marine industry, Airframe components, Cryogenic vessels Heat exchangers, CPI equipment, Condensor tubing, Surgical hardware, Pickling baskets, Chemical processing, Chlorate manufacturing, Desalination, Marine applications, Aircraft turbines, Engine components, Aircraft structural components, Aerospace fasteners, High-performance automatic parts, Marine applications, Sports equipments, Orthopedic pins and screws, Orthopedic cables, Ligature clips, Surgical staples, Springs, Orthodontic appliances, In joint replacements, Cryogenic vessels, Bone fixation devices, Shell and heat exchangers, Hydrometallurgical applications, Elevated temperature chemical manufacturing, Marine and airfare components

Carbon Steel Pipes Are Widely Used in Industries Due to Its Multifarious Specifications

You will always find the black steel pipe in the multifarious industrial department for they are prominently used there. They are available in a wide range of specifications for carbon steel pipes with each of them designed to have high strength and integrity. The carbon steel pipes are made up of carbon and iron as basal materials.

However, since they are built into structures that have no seams, the pipes can also be known as seamless steel pipes. For the incredibly high strength of these steel pipes, the absence of the seams is responsible.

The absence of the seam also explains why, when used to transport flammable gases, the pipes would not release gases. This is the concept that seamless carbon steel pipe manufacturers have adopted. Providing that the component elements are regulated in a planned and acceptable range, the steel will be referred to as carbon steel with respect to the proportion of carbon and iron.

In comparison to this, however, if the proportions of these components are surpassed, the steel will be said to be alloy steel or some other type. Copper at a proportion not exceeding 0.4 percent and manganese at a proportion not exceeding 1.65 are the main elements needed in the formation of carbon steel.

Carbon is introduced as an additive during the manufacturing process to increase the reliability of the steel permits. Based on the carbon content, carbon steel is divided into various groups.

This explains why it’s easy to get on the market with carbon steel. There is a generic identity number allocated to it, regardless of the large variety of carbon steel seamless pipe producers on the world market today. This helps to distinguish from others a trustworthy supplier of seamless steel pipes.

The Carbon steel fittings are significant for the various types of pipe systems. However, depending on the dimensions of the steel pipes, there are various designs of the fittings used to match them. The part of the fittings is important to remember as it should also be made from steel.

With the same component components, just as the basal pipes, it is simpler to ensure that the fittings withstand the same strength. It is crucial to ensure that it fits the diameter of the pipes you are using when considering your choice of fittings. Say that the pipe diameter you’re using is 4 inches, using the available lap joins, you are sure to satisfy your requirements.

It is important to consider this when choosing your seamless carbon steel pipe manufacturer. The bottom line here is that specially crafted fittings are needed for your specialty pipes. For instance, different industries go to meet their different industrial applications for customized multiple black steel pipe specifications.

As they are constructed according to the different applications, it is necessary to understand how to choose a proper steel flange.

These are the Important Three Benefits of Commercial Seamless Steel Pipe

The manufacturing process of commercial seamless steel pipe starts with a solid, round steel billet. This billet is then heated to high temperatures and stretched until it takes the shape of a hollow tube and is pulled over a form.

The Seamless Steel pipes transport fluids such as natural gas, water, waste, and air. There are three manufacturing methods to manufacture seamless steel pipes that exist. A strong, round steel billet begins with the seamless steel pipe manufacturing process. This billet is then heated to high temperatures and stretched until it takes the shape of a hollow tube and is pulled over a form.

What are the benefits of Commercial Seamless Steel Pipe?

There are three important benefits of commercial seamless steel pipes.

Increased Pressure Ratings

The greatest benefit of seamless steel pipes is their improved pressure-resistant capacity. In a welded steel pipe, the weakest point is the welded seam. Unlike welded, Seamless pipe does not have a seam making it similarly solid across the entire diameter of the pipe. It is also much simpler to calculate pressure measurements without being needed to take weld quality into account.

While seamless pipes can often be more costly than welded pipes, this improved pressure-resistant capacity allows you to use thinner and lighter pipes, which can help reduce costs.

Strength under Loads

Seamless steel pipe may often be more costly than other steel pipe types, but it’s also more efficient. This is because, under loading, it has greater intensity. The empty pipe must still support its own weight, but it also needs to support the weight when a pipe is loaded with material or under load. Pipe failures and leaks typically occur in a welded seam. But it is not subject to such failures since the seamless pipe does not have a seam.

In a range of industrial pipe applications, such advantages make seamless steel pipes the preferred material, including shipbuilding, pipelines, oil rigs, oil field equipment, pressure vessels, machinery parts, and offshore rigs. An additional advantage of seamless pipes is that in harsh conditions they perform well, which means they can be used in extremely cold or hot environments.

Uniformity in the Shape of the material

By continuous extrusion of the alloy, the seamless ones are prepared, creating a circular cross-section that anyone can count on.

The shape of the pipe is bent, adds tension & extraneous variable to the pipe during the production process, which never results in a round pipe or hollow rods such as seamless ones, unlike the welded ones, which are prepared by wrapping & welding the sheet on each other. The seamless uniform pipes allow the installation & fittings process to be simple.
