Spiral Mill
SAWH
The factory is the largest spiral pipe manufacturing plant in the south of the country
and has the highest production capacity in this area. With its advanced technology, it
has the capability to manufacture steel tubes used in oil, gas and water transmission
lines in accordance with international standards and standards of the National Iranian
Gas Company and the National Iranian Oil Company.
Factory 2 with advanced equipment and up-to-date control systems, such as SAWH
automatic welding equipment,
On-Line, Off-Line, Plasma Cutting, Automatic Welding, Ultrasonic Testing Machine
(On-Line, Off-Line), Double-Threading Machine, Hydraulic Pressure Test Device (HID),
Capable of producing all kinds of pipes Steel has a capacity of 180,000 m / ton to 250,000 m
/ ton per year.
The manufacturing method in this factory is that the clay sheet, after opening, leveling and
preparing its edges, is subjected to a shaped and shaped set at a given angle based on the
diameter and thickness of the pipe. After the forming step, the seam of the pipe is in the
off-line production mode by the GMAW method (protective gas welding) and in the form of
Tack-Welding and in-line (welding) method Powder) is fully welded. After that, the tube is cut
to the required length (typically 12 meters) by the plasma cutting system with very high
precision and then sent to the next steps.
At this stage, the off-line produced pipes are used for welding purposes to be submerged by
welding machines from the inside and outside of the welding.
All of the pipes manufactured by this factory are tested and tested in accordance with the
standards of the day to ensure its proper conditions. These tests, which take place at various
plant stations, include MT, VT, UT as well as water pressure test. In order to ensure the
quality of production process according to the requirements of the standard and customer's
requirements, different samples from the factory are sent to the quality control laboratory to
conduct malware testing.
It notes that all welding machines and other equipment in this factory are equipped with
advanced PLC control system, which guarantees the quality of the product.
