Located in the industrial area of Thisvi, in Greece’s Viotia prefecture, the Thisvi plant is considered one of the most modern steel pipe manufacturing mills in the world. The plant commenced full operation in 2001/2002, has a total area of 497,000 m2 (103,000 m2 of which are covered), and exclusive use of port facilities just 1.5km away. The plant’s personnel are highly skilled and valuable contributors to our successful business performance and sustainable growth.
The Thisvi plant’s state-of-the-art production equipment is used to manufacture steel pipes to the highest standards for the Oil and Gas industry and hollow sections for the construction sector. Its in-house external and internal coating facilities, as well as its other downstream operations and services, have established Corinth Pipeworks (CPW) as a one-stop-shop supplier of the world’s market.
CPW operates four pipe mills (one 7” ERW/HFI mill, one 26” ERW/HFI mill, one 100” SAWH mill and one 56” LSAW mill) with a combined annual production capacity of 925,000Tn. CPW also operates two external and one internal coating mills.
26"ERW/HFI pipe mill
The raw material used in high frequency induction welding (ERW/HFI) is a hot rolled steel coil. The edges to be welded are mechanically pressed together and the heat required to generate the weld is created by the resistance of the edges to the electrical current flowing through them.
The ERW/HFI pipe mill manufactures pipes with diameters ranging from 8 5/8” to 26”, steel grades of up to X80, wall thicknesses ranging from 4.78 to 25.4 mm and pipe lengths of up to 23.2 m. The ERW/HFI pipe mill also manufactures large hollow structural sections (ranging from 180x180 to 500x500 and 600x400 mm) widely used in the metal construction sector. The mill was built by the German firm, SMS-Meer.
7 5/8” ERW/HFI pipe mill
This ERW/HFI pipe mill manufactures pipes with diameters ranging from 2” to 7 5/8”, steel grades of up to S355J2H and wall thicknesses ranging from 3 to 10 mm. The ERW/HFI 7 5/8” steel pipes are widely used in the construction sectors, for networks and drilling. The mill was built by the German firm SMS-Meer.
100” SAWH mill
The Submerged Arc-Welded Helical (SAWH) mill manufactures large diameter steel pipes from high quality hot rolled steel coils. Welding is achieved by joining the ends of the metal together using submerged arc welding (SAW) techniques. The SAWH mill manufactures pipes with diameters ranging from 24” to 100”, with steel grades of up to X80 and wall thicknesses ranging from 6.00 to 25.4 mm. The mill was manufactured by the German firm MEG / SMS-Meer.
56’’ LSAW pipe mill
In 2015 we completed our investment in the LSAW-JCOE pipe mill. LSAW large diameter and high wall thickness pipes are manufactured using longitudinal submerged arc welding technology, and are used primarily for offshore pipelines. The raw materials used are hot rolled steel plates of a specific width and length depending on the specifications of the project. The new mill is able to manufacture pipes with external diameters ranging from 16” to 56”, wall thickness of up to 40 mm, pipe lengths of up to 18.3 m, and steel grades of up to X100.
Weld-on connectors’ facility
This facility offers weld-on connectors’ solutions for casing pipes, offering customers a comprehensive end-product. The weld-on connectors’ facility is run in partnership with MITE and OSI, and offers services to the Mediterranean market. The facility is able to handle pipes with a diameter from 6 5/8” to 42”, steel grades of up to X100 and wall thicknesses of up to 25.4 mm. The facility was built by Corinth Pipeworks and OSI.
External coating mills
TCP 48 mill: This mill applies external coatings such as triple layer of polyethylene (3LPE), polypropylene (3LPP) and single or dual layers (FBE) of fusion bonded epoxy. The TCP 48 mill is able to coat pipes with an external diameter of up to 48”.
TCP 100 mill: This mill provides similar external coatings for pipes with an external diameter of up to 100”.
TCP 100 mill recently underwent an upgrade to enable coatings to be applied to pipes up to 23.2 m long.
Internal lining mill TLP 56 mill:
The TLP 56 mill provides internal coating for steel pipes with epoxy lining materials. It is able to process pipes with an external diameter of up to 56”. This mill recently underwent an upgrade to enable coatings to be applied to pipes up to 23.2m long.
