Spiral Welded pipe production line
GEIT Pipe welding equipment factory is located at Hebei, China, it has a combined capacity of 0.6 MTPA of Spiral submerged arc welded (SSAW) and longitudinal submerged arc welded (LSAW) steel pipes along with internal and external coating facilities of up to 2mn square meters annually.
Automated systems and processes help in real time tracking of pipes until dispatches.
Minimal human interference ensures a high degree of precision and consistency.
High production to manpower ratio due to automation of processes.
Spiral Submerged Arc Welded Pipes Line:
Spiral submerged arc welded (SSAW) pipes are made from HR coil, where the coil is welded spirally to give a shape of pipe with the capacity to produce 270,000 tonnes of HSAW pipes. It manufactures high quality HSAW pipes conforming to international quality standards. One of the unique features of the two-mirror image HSAW mill is that it can manufacture pipes of same size or two different sizes simultaneously at a very high speed, thereby drastically reducing the delivery time.
The manufacturing process used for SSAW pipes consists of two steps:
Pipe forming combined with continuous tack welding
The two step technology offers both quality and economic Benefits such as:
High pipe forming speed by continuous Tack Welding
Emphasis on pipe geometry on pipe forming machine without hindrance by SAW process, resulting in tightest tolerance even without cold expansion with respect to:
Straightness
Roundness
Accuracy of diameter
High quality due to implementation of process automation technology
HSAW forming mill has main drive feed motor with 500,000 Nm torque enable to form pipe of 1 inch wall thickness comfortably.
Plant Configuration: S-SAW
Diameter 16" to 100"
Grade API X80
Thickness 6.0mm to 25.4mm
Pipe Length (max) 12 meter
Current Capacity 275,000 TPA
Technology Support Byard; Phamitech
The SAW pipes manufactured from plates are called longitudinal submerged arc welded (LSAW) with an installed capacity of 330,000 TPA. The manufacturing facilities incorporate the hybrid JCO&E technology, which provides flexibility in terms of thickness & grade. The facility also possesses latest inspection and testing equipments to meet specific requirements on execution, strength, tolerance, length etc. The Mill also has valid licenses to use API Monogram.
Salient features of LSAW:Capacity to produce pipes with very close Diameter Thickness ratio
Ultrasonic Testing to ensure internal soundness of steel plates used for producing pipes
LSAW Mill is equipped with 6000 MT JCO press, having capacity to form pipes of 60 mm WT.
Cold Expander (13m) to ensure tight and uniform control on pipe dimensions
Plant Configuration: L-SAW
Diameter 16" to 64"
Grade API X80

Coating is an effective method to prevent corrosion, resist erosion and enhance operational life of line pipes. Pipe mill has imported technical know-how from Italy-based Socotherm, pioneers of coating. The facility deploys external coating like Fusion Bonded Epoxy (FBE), Dual layer FBE, 3 LPE, 3 LPP and Polyurethane, which are latest methods to prevent corrosion and internal coating like Cement Gunniting, Liquid Paint and Corrosion Resistance techniques to prevent corrosion and improve product flow.
Salient features of coating :
Deploys buggy system, which facilitates pipe specification and eliminates air entrapment.
Pipe curing system enables higher productivity
The coating facility is designed to maintain dust-free atmosphere by separating shot blasting and coating.
Cold Expander (13m) to ensure tight and uniform control on pipe dimensions
Coating Unit Configuration:
Diameter- external 4" to 60"
Diameter- internal 8" to 60"
Pipe weight 15 MT (max)
3 LPE 2 Mn sq mt
Liquid Epoxy 1 Mn sq mt
Quality
To cater to the wide range of pipe products manufactured through various routes, Pipe mill has full-fledged facilities for inspection and testing to ensure production of high quality.
