Multilayer Composite Pipe Production

Multilayered composite pipes made from stainless steel and other alloys combined are ideal for pipes for water, hot water and sanitary sewerage applications. However, precision molding processing technology is indispensable for its production. T.H.E. Machines responds to it with their outstanding metal plastic molding technology.
In addition to TIG welding, T.H.E. Machines also has laser welding technology that does not use shielding gas, while maintaining high-speed production speed so that they can accommodate seamless thin wall thickness up to 0.08 mm.
T.H.E. Machines will provide complete lines including downstream process such as accumulator, capstan, dancer, dual coiler etc.

Product Features

Plastic pipe extrusion:

Inner and/or outer plastic, with THE own or customer bespoke extruders. Integrated polymer mixing, dosing and feeding available as well as layer thickness control.

Metal Roll forming:

In-house manufactured precision roll-forming tools engineered with finite element simulations to impart minimal stress and strain, avoid surface damage and provide process stability. High quality and use of materials assure longevity of the tools. Quick-change carrier systems benefit in low set-up times and operational excellence.

Welding:

High quality laser welding with proprietary orbital seam tracking system. Laser power source and beam quality adapted and configured to best suite the application.

Quality Control:

In-line monitor and measurement of all geometric parameters with fully integrated in-line continues non-destructive weld seam and tube quality control systems with exclusive ICO (Internal Crack Observer) and ECC eddy current measure.

Line Controls:

Centralized line control systems, with recipe management to assure process stability and operational excellent. Line controls have data logging capabilities for track and trace requirements of key required process parameters and quality checks as well as prepared for customer industry 4.0 requirements. User friendly HMI and line management systems.
