Tube Mill

In 2001, Excel embarked on its commercial journey in the production of Pipes and Tubes, primarily aimed at securing a reliable supply for our renowned Scaffolding and Formwork Manufacturing Division.

Our comprehensive range of steel tubes and pipes adheres to esteemed international standards, including ASTM, BS, JIS, SAE, AISI, and DIN. At Excel, we have fostered a robust local and regional reputation grounded in meticulous engineering, top-tier manufacturing practices, and the procurement of premium raw materials sourced from integrated steel plants spanning the globe. Employing cutting-edge technology, our high-speed pipe manufacturing processes encompass circular, square, and rectangular steel tubes, all executed with utmost precision.

The fabrication of Electric Resistance Welded (ERW) Pipes / Tubes is a seamlessly automated procedure. Hot Rolled Steel Coils are meticulously uncoiled, leveled, and subsequently slit into precise strips. These strips are seamlessly fed into the Forming Mill, where they undergo pipe shaping and formation, culminating in a flawless fusion accomplished by our High-Frequency Induction welder. The resulting welded points exhibit the same unwavering strength as the base metal itself. To achieve superior results, the formed pipes undergo meticulous air and water cooling, culminating in a sequence of accurate sizing, cutting, and straightening processes.

ERW PIPE / TUBE PRODUCTION

Typical ERW Pipe/Tube Manufacturing Process:

Our manufacturing process generally involves the following stages in a step-by-step procedure.

Coils are slit to predetermined widths for each and every size of pipes/tubes.
The slit coil is uncoiled at the entry of the ERW mill. The ends are sheared and welded one after another, resulting in a single endless strip.
Industo is strongly involved in creating a zero emission society by being a pioneer in these changing times. Our versatile services help bring success to Nordic and international companies in the industry, energy, telecommunications and construction sectors.
The open edges are heated to the forging temperature utilizing a high-frequency, low-voltage, high current. They are press welded by forge rolls which ensures a perfect, strong weld without utilizing any filler materials.

The parts that are hot, or that have been welded, are cooled and normalized in an air-cooling bed.
After water quenching, the desired outside diameter is produced by a slight reduction that is applied to the pipes. This process utilizes sizing rolls.
The pipes are then cut to length by a flying cut off disc/saw cutter.
The pipe ends require finishing. This process is referred to as end facing.
This production process is steady, continuous, and automatic.

Our Tubes and Pipes are versatile enough to be used in various industries and reasons including Electrical and Gas transmission, Liquid transportation, Oil and gas drilling, Irrigation, Petrochemical piping, pharmaceuticals, Structural, Hydro form, and Mechanical tubing as well as Exhaust pipes.
