What is ERW Pipe?
Pipe and profile products used in the industrial, construction, energy, and infrastructure sectors offer different performance levels depending on production technologies. ERW pipe, which constitutes the majority of these products, has become one of the basic products of the modern steel industry due to its high production precision, durability, and wide range of applications.
What is ERW (Electric Resistance Welded) Pipe?
ERW pipe is a type of pipe produced by welding two steel edges together using high-frequency electric current. This production method ensures a strong bond at the seam of the pipe and provides an extremely reliable structure in terms of strength.
User Advantages of ERW Pipes
- ERW pipes generally have a more affordable cost structure compared to seamless and spiral-welded pipes. This provides an economical solution, especially for applications requiring low and medium pressure.
- ERW pipes, which are mass-produced, offer fast supply and easy planning for projects thanks to their wide range of size options.
- ERW pipes are commonly preferred in systems that require small to medium diameters. This feature expands their scope of use for lightweight construction systems and general industrial applications.
- Their consistent structure in terms of diameter and wall thickness ensures compatibility and ease of application during installation processes.
- Thanks to these technical advantages, ERW pipes are heavily preferred in the water, gas, construction, automotive, furniture, and energy sectors.
Box Profiles and Profile Types
Box profile products used in industrial structures and architectural systems are among the most preferred structural elements in modern engineering solutions. Profile types offer different features depending on the production method and application areas.
Most Common Profile Types:
- Square profile
- Rectangular profile
- Special section profiles
These profiles play an important role in steel construction, particularly because they provide both static strength and aesthetic integrity.
Areas of Application for Square and Rectangular Profiles
Square and rectangular profiles are used in many areas, including construction, steel construction, furniture production, automotive parts, and machine manufacturing.
What Are the Applications of Square Profiles?
- Steel construction systems
- Machine chassis
- Railings and architectural applications
- Lightweight carrier systems
What Are the Applications of Rectangular Profiles?
- Structures requiring high load-bearing capacity
- Roof and facade frames
- Industrial shelving systems
- Load-bearing projects where pipe form is not required
One of the most important factors in the production of these profiles is wall thickness, offering a wide range of applications from lightweight construction solutions to aesthetic design projects.
How Are Pipe & Profile Manufactured?
Pipe and profile manufacturing involves shaping and welding steel sheet. High-frequency welding (HF-ERW) technology is used in production. This method ensures that pipes and profiles are of the highest level in terms of both strength and dimensional accuracy.
Pipe & Profile Production Stages
- The production process begins with the procurement of hot or cold rolled steel sheets of appropriate quality and standards.
- The procured steel sheets are converted into strips on the production line and prepared for shaping.
- The strip sheets are transformed into the desired pipe or profile geometry using forming mills.
- The shaped products are joined using the electric resistance welding (ERW) method to create a continuous and homogeneous weld line.
- Post-welding burrs are removed, and the product surface is corrected in terms of dimensions and surface quality.
- Final products undergo testing and quality control processes to ensure compliance with mechanical, dimensional, and surface quality criteria.
