Ströman . HDPE Pipe Production Technology

It can be said that the current technology being applied to produce HDPE Ströman branded products is the most integrated of the plastic industry in the world. Let's find out the details right here!

What is HDPE?

HDPE (High-density polyethylene) also known as PEHD (polyethylene high-density) is a high-density thermoplastic material. HDPE is known for its great strength-to-density ratio. The density of HDPE can be in the range of 0.93-0.97 g/cm3 or 970 kg/m3.

Although the density of HDPE is only higher than that of low density thermoplastic (LDPE) polyethylene, because HDPE has less branching, it has strong intermolecular forces and therefore higher tensile strength. LDPE.

     c. Energy industry

  • Making electrical conduit, electric cable
  • Making hot steam pipes (heating pipes)
  • Make a drainage pipe
  • Making cold water supply pipes (pressure 4-10kg/cm2)
  • Making pipes for the postal industry, fiber optic cables where the temperature is low (ice and snow)​

HDPE pipe production technology

Transferred by machinery, technology, operation and control from German experts, Ströman HDPE pipes integrate the highest values of the plastic industry in the world into its products.

With the standard Smart factory 4.0 format, the Ströman HDPE pipe factory is invested in a synchronous and modern manner from the infrastructure to the system of machinery, equipment, technology and control processes in strict accordance with the standards. European standards.

Modern machinery system of Krauss Maffei Group (Germany)

Ströman HDPE pipes are manufactured on a technological line provided by Krauss Maffei (Germany) to help control all processing parameters and control all closed equipment with high precision. The automatic feeding system imported from AZO supplier, Zeppelin (Italy), helps control the whole process of weighing and mixing automatically with an accuracy of up to 99.9%, ensuring high optimization.

The whole system of saws and expanders are imported from supplier SICA (Germany), applying infrared heating technology, helping the socket coupling achieve 100% uniform profile when connecting pipes, solving thoroughly so that leakage problems often occur for common products. The line system is fully automated, minimizing human involvement from the dosing and mixing stages of materials to packaging finished products, creating accurate, uniform and multi-dimensional products. size format.

In addition, in order to ensure uniform quality, Ströman has also built and maintained a strict and rigorous quality management system, ensuring that all manufactured products meet German standards: according to German standards. German standards such as DIN 8077:2008-09, DIN 8075:2011-12… The standard clearly stipulates the elements of food safety and hygiene, the size of the standard designation, the permissible working pressure and the designation of materials. material that makes up the pipe, as the affirmation of the durability and safety of HDPE Ströman pipes.

Operated and controlled strictly by German experts, applying German technology lines, ensuring German standards, Ströman HDPE pipes and fittings have completely convinced the fastidious customers. best.
