Two-piece steel pipes are specialized installation components used in transmission, sewage, rehabilitation and trenchless technologies. The split construction enables quick installation on existing pipelines or in locations where a standard single-piece pipe cannot be used. Impostal supplies two-piece pipes in a wide range of diameters and wall thicknesses, meeting the needs of industrial, infrastructural and municipal projects.
Dimensional Range and Configurations
Available pipes range from 114.3 mm to 2420 mm in diameter, with wall thicknesses from 3.6 mm to 100 mm. This allows for precise selection based on load conditions, medium type and installation requirements.
Produced in standard sections:
3000 mm – DN125 to DN2400
2000 mm – DN125 to DN2400
1500 mm – DN125 to DN2400
1000 mm – DN125 to DN2400
The welded split structure is tight, stable and recommended for applications requiring high durability and pressure resistance.
The bolted variant allows for repeated assembly and disassembly. It is ideal for rehabilitation, emergency work and applications where quick installation is crucial without the need for heavy welding equipment.
Materials and Components
Two-piece steel pipes offered by Impostal are made from materials ensuring high mechanical resistance and long service life:
Carbon steel min. S235 – standard and versatile.
Fasteners: galvanized steel; optionally A2 or A4 stainless grades.
Gaskets: NBR rubber (standard), optionally SBR or EPDM.
Customization Options
Impostal offers fully customizable pipe configurations:
Lengths from 500 to 12,000 mm – adaptable to installation needs.
Material versions: galvanized steel and stainless steels 1.4307 and 1.4404.
Fasteners in A2 and A4 corrosion-resistant classes.
Seals: NBR, SBR, EPDM – selected based on medium and operating conditions.
Protective coatings: epoxy and polyurethane for enhanced corrosion resistance.
Accessories: system skids, sleeves.
Applications of Two-Piece Steel Pipes
These pipes are used in water and sewage systems, process pipelines, stormwater installations, and for replacing or protecting existing conduits. Thanks to their split design, they are also suitable for repair and protective works where installation of a full pipe would be difficult.
Why Choose Impostal Solutions?
The company ensures high manufacturing standards, production flexibility and the ability to handle non-standard orders. Two-piece steel pipes from Impostal are durable, corrosion-resistant and easy to install, helping reduce project execution time and increasing overall system reliability.
