Today, Pearlite Steel will discuss about the key difference between Seamless and ERW Stainless Steel Pipe

What is the Raw material required for manufacturing Seamless & ERW Stainless steel Pipes?

Seamless Steel Pipe is made from a solid round steel &#;billet&#; which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Billets are procured both from indigenous suppliers and from abroad. Major Indigenous suppliers are JSPL, JSW & Kalyani and steel round billets are imported from renowned mills from Europe, Far East countries, Canada, China.

To Manufacture ERW Stainless Steel Pipes HR Coils are required. Major Indigenous suppliers of these HR Coils are SAIL, Essar, JSW, Lloyds etc.

What is the Difference Between Seamless and ERW Stainless Steel Pipes?

Electric Resistance Welding (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; therefore ERW pipe have a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.

In Seamless pipe, there are no welding or joints and is manufactured from solid round billets. The seamless pipe is finished to dimensional and wall thickness specifications in sizes from 1/8 inch to 26 inch OD. Applicable in for High-pressure applications such as Hydrocarbon Industries & Refineries, Oil & Gas Exploration & Drilling, Oil & Gas Transportation and Air and Hydraulic cylinders, Bearings, Boilers, Automobiles
etc.

ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured upto 24&#; OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through a electric charge. It is mainly used for low/ medium pressure applications such as transportation of water / oil. Pearlites steel is one of the leading ERW Stainless Steel Pipes Manufacturer and exporter from India. Contact us for product details.

Common sizes for ERW Steel Pipe range from 2 3/8 inch OD to 24 inch OD in a variety of lengths to over 100 feet. Surface finishes are available in bare and coated formats and processing can be handled on site to customer specifications.

 

What Technologies are used to manufacture Seamless & ERW Pipes?

Technologies for Production of Seamless & ERW Pipes &#;CPE&#; Technology&#; used for Seamless Pipes & Tubes Production up to 7-inches OD is the world renowned Technology. &#;Plug Mill&#; Technology used for Higher Dia. Seamless Pipes & Tubes Production from 7-inches to 14-inches,is the most reliable technology,in higher dia. Segment. High frequency Induction Welding Technology is used for ERW Pipes &Tubes upto 21-inchesOD.

 

How to Identify Seamless or ERW Stainless Steel pipes?

To identify that a pipe supplied is seamless or ERW, Simply read the stencil on the side of the pipe

If it is ASTM A53, Type S means seamless.
Type F is furnace but welded,
Type E is Electrical resist welded.
Thats how. It is the easiest way to identify wether pipe is seamless or ERW.

In short, Seamless is marketed on an outdated myth that it does not have flaws but that welded has an inherent flaw throughout the length of each tube, as stated above. Intuitively this concept is easily accepted by purchasers and designers with limited experience with the various products. Each product form and manufacturing method has its own inherent problems and potential defects.

Consumers must become familiar with what those problems and defects are, and how they might affect particular applications. Then they can make an informed decision based on facts, rather than myth.

Where are ERW Pipes Used?

What is an ERW pipe?

is a type of steel pipe made by welding steel coils lengthwise. ERW steel pipes are made from steel strips formed into a cylindrical shape and then welded together. Welds are formed by applying pressure and electric current to the steel to melt the edges of the steel and fuse them together. ERW pipe is available in various sizes and thicknesses to meet the requirements of different applications. ERW pipe is widely used in a variety of applications due to its strength, durability and cost-effectiveness.

Advantages and disadvantages of ERW pipe:

One of the main advantages of ERW steel pipe is its cost-effectiveness. Compared to other types of pipe, such as seamless or spiral-welded pipe, ERW pipe is less expensive to manufacture and easier to produce in large quantities. This makes them a popular choice for applications requiring large amounts of pipes.

Another advantage of ERW pipe is its strength and durability. ERW pipes are made from high-quality steel and are resistant to corrosion, rust, and other forms of degradation. This makes them suitable for applications requiring high strength and durability, such as the construction, oil and gas, and automotive industries.

However, ERW pipes also have some disadvantages. One of the major disadvantages of ERW pipes is that they are not suitable for applications requiring high pressure or temperature. They also have less dimensional accuracy than seamless pipes, which can cause problems with fittings and connections.
