Process Flow Chart
Manufacturing Process of ERW Pipes
Experience the transformation of HR coils into ERW pipes and tubes, where advanced technology and expert craftsmanship come together to produce high-quality products. The manufacturing process for our ERW pipes and tubes begins with unrolling steel coils, followed by leveling, cutting, forming, welding, cooling, sizing, and precise cutting to the desired length. This process concludes with a thorough inspection to ensure that each pipe and tube meets our stringent quality and performance standards.
Various forms of ERW Pipes
RHS (Rectangular Hollow Sections)
Rectangular hollow sections (RHS) are a popular choice for mechanical, structural, and construction applications. This is due to the flat surface resulting in a structural solution that is more economical for joining and various other types of fabrication work.
SHS (Square Hollow Sections)
Square hollow sections (SHS) are a popular structural steel tube. They combine the attributes and structural behaviour of RHS and CHS. SHS features a flat surface that’s also economical for joining and welding, with clean lines and minimal edge preparation required.
CHS (Circular Hollow Sections)
Circular hollow sections (CHS) were the first form of hollow section and are commonly used in a wide range of structural, mechanical, and construction areas. CHS are favoured for their uniform strength, smooth appearance, and versatility.

Universal testing machine
Universal Testing Machine
A Universal Testing Machine (UTM) is used to assess the tensile and compressive strength of materials. The term "universal" indicates its ability to perform a broad range of standard tensile and compression tests on different materials, components, and structures; showcasing its versatility.
Hardness testing machine
Hardness Testing Machine
A hardness tester is a device used to measure the hardness of a material by evaluating how deeply a standardized indenter penetrates its surface. This indenter can be either rounded or pointed and is commonly made from materials such as diamond, carbide, or hard steel. One popular type of hardness tester is the Rockwell hardness tester, which employs either a steel ball or a conical diamond known as a "brave." This tester measures hardness by assessing the depth of the indenter's penetration under a specific load, compared to its position under a smaller initial load. The resulting hardness value is then displayed on a dial.
Tube Bending Machine
Tube Bending Machine
Pipe bending machines are used to bend pipes and tubes, allowing for the creation of curved sections. These machines have various applications including pipe sealing, bending, assembly, and breaking.
Chemical Spectrometer
Chemical Spectrometer
A spectrometer is an analytical instrument used in spectroscopy to produce and measure spectral lines, including their wavelengths and intensities. It effectively separates particles, atoms, and molecules based on their mass, momentum, or energy. Spectrometers play a crucial role in both chemical analysis and particle physics.
Hydro Testing Machine
Hydro Testing Machine
Hydrostatic testing is a method used to pressure test equipment and pipelines with water, ensuring their integrity and identifying potential leaks.

FAQs
Frequently Asked Questions (FAQs)
-
Q1. What are MS-ERW Pipes?
-
Q2. What are the different types of MS-ERW Pipes?
MS-ERW pipes are available in three different types: CHS (Circular Hollow Sections), SHS (Square Hollow Sections), and RHS (Rectangular Hollow Sections).
-
Q3. What is the difference between GI & MS Pipes?
GI Pipes: These are mild steel pipes that are coated with a layer of zinc (galvanization) to protect them from rust and corrosion. This makes them ideal for outdoor use or applications where the pipes are exposed to moisture, such as water supply or irrigation systems. The zinc coating extends their lifespan in wet conditions but they are generally more expensive than MS pipes.
MS Pipes: These are made from plain mild steel without any protective coating. While they are cheaper, they are prone to rust if exposed to moisture or harsh weather. MS pipes are often used in indoor applications or where extra coating (like paint or anti-rust treatments) can be applied to protect them.
-
Q4. What is the manufacturing process of MS-ERW Pipes?
The manufacturing process of MS ERW (Mild Steel Electric Resistance Welded) pipes involves forming a steel sheet into a tube shape and then welding the edges together using electric resistance heat to create a continuous seam.
-
Q5. What are the different types of square pipes and what are their uses?
The choice of square pipe depends on the specific material (mild steel, stainless steel, aluminum, etc.), the coating (galvanized or uncoated), and the application (construction, industrial, or decorative). Each type offers its unique advantages depending on factors like strength, weight, corrosion resistance, and cost.
-
Q6. What is the role of MS pipes in scaffolding structures?
MS pipes (Mild Steel pipes) play a crucial role in scaffolding structures due to their strength, durability, and cost-effectiveness. Scaffolding is temporary support used in construction and maintenance work, and MS pipes are commonly used as the main structural components.
-
Q7. What are the common applications of IS 1239 certified ERW Pipes?
IS 1239 Certified ERW (Electric Resistance Welded) pipes are widely used across various industries due to their strength, versatility, and compliance with Indian standards for mild steel pipes. These pipes are commonly used for both low-pressure and medium-pressure applications and are especially recognized for their use in plumbing, construction, and industrial systems.
