Our products

Product category: Extrusion lines for pipes and profiles

KR production line - The high performance plastic pipe production technology by Krah Made in Germany

The KR Series is the single screw high performance helical extrusion line of Krah, which is a complete plastic pipe production plant, to produce structures wall (acc. DIN16961, etc.) or solid wall pipes (acc. ISO 4427 etc.) on internal diameters from DN 300 mm up to DN 5000 mm made out high density polyethylene or polypropylene. Even fittings, manholes and tanks can be produced with only one single KR Line, to cover more market segments.

Pipes can be produced in lengths from 1m up to 6m and on special request even longer, on any required wall design according the international standards. The main applications for the structured wall pipe products are low, non -pressure applications like for sewer, drainage, storm water, sea outfall/intake, irrigation systems and or even storage tanks. The possibility to determine the most efficient pipe wall design with Krah Software Mickey, assures the customer to produce pipes, fittings and manholes according the standards and as an add value according the project requirements.

The newest Krah Line is KR800-max with approximately 1.500 kg/hr output for a pipe DN/ID1000, PE100, with SN8 (according to ISO9969). The great advantage of the development is that a profiled pipe has lower weight in comparison with solid wall pipes and at the same time can be used very cost efficient for environments with high loads. Significant cost saving and continuous production assures the customer, excellent production and sales result. Furthermore, every pipe can be produced with an integrated socket and spigot for the most cost efficient and sustainable jointing solution electro fusion.

KDR production line - The high performance plastic pipe production technology by Krah Made in Germany

The KDR Series is a twin screw helical extrusion line of Krah, which is a complete plastic pipe production plant, to produce structured wall (acc. DIN16961 etc.) or solid wall pipes by using fillers like CaCo3/Glassfibre etc., on internal diameters from DN 300 mm up to DN 5000 mm made out high density polyethylene/polypropylene, reinforced/mixed with glassfibre or CaCo3.

  • Glassfibre reinforced polyethylene (PE-GF)
  • Polyethylene/polypropylene with filler material
  • Virgin polyethylene or polypropylene
In a huge market of competition, cost savings by using filler materials becomes more and more important for pipe manufacturers. The production technology with the twin screw extruder is compounding filler material with the polyethylene or polypropylene to assure the same stiffness or pressure rate compared to traditional produced pipes.  The glassfibre reinforced polyethylene pipes (PE-GF) are mainly used for pressure pipe application and pipe jacking. The compound with filler material are used to increase the stiffness significantly for buried pipe application. Production line can be equipped for solid wall production only as also for profiled wall structure pipes.

Krah Pipes - The high-performance plastic pipe production technology by Krah Made in Germany

Leak free, sustainable, homogenous and flexible Krah Pipe System

Since generations the mankind is busy by transporting water/sewer or any other liquids from one point to another point. The challenge was always to assure a conveyance system without fails and leakage. Most pipe failures were occurring on the joints through corrosion or cracks on the rigid inflexible pipe material.

Over the last decades, the inherent weaknesses of concrete, clay, ductile, PVC and steel caused tremendous problems in existing water supply, sewer pipes systems, as they tend to be brittle or are too sensitive for aggressive chemicals and soil conditions. Leakages have become a common occurrence worldwide in water, sewer and other large diameter pipe applications. In addition, they have an unprofitable relationship between cost and benefit due to short life time and high maintenance costs.

Krah Pipes are made out different grades of pure Polyethylene or Polypropylene who are providing superior properties against corrosion, leakage, pipe displacement and ex-infiltration. In addition to the permanent solution that lasts through generations, the Krah piping system is able to provide a sustainable, environment friendly and economical solution with its wide-ranging fields of applications, f.e. water supply, sewer systems, drainage, storm water management, sea outfalls/intake, manholes and reservoirs.

In order to meet the demand of the at least 100 years leak free, sustainable and flexible pipe system, Krah Pipes are produced with an integrated electro fusion joint system, which assures a melting of the pipes to a homogenous and monolithic pipe system.

Krah Pipes can be produced from the following thermoplastic materials: 
  • High density polyethylene (PE80 and PE100))
  • Polypropylene – random (PP-R, PP-B)
  • Polypropylene – homo (PP-H)
  • Flame retardant polypropylene (PP-S)
Other materials can be used after prior acceptance of the producer and a third party for quality control.

About us

Company details

As a family-owned company with an almost 50-year history we possess the essential base for being successful on the global market.

Our company is rooted in a small engineering company specialized on the design of small machines and tools founded by Karl-Heinz Krah in the year 1968. During the past years the company has developed from a small workshop and „one man show“ to a worldwide successful machine manufacturer specialized in plastic pipe production plants in big diameters for non - as well as pressure pipes. Today the machines are developed, built and put into operation by the “Krah Advanced Technology GmbH” – shortly “KAT GmbH”. The sales is carried out structurally by the “Krah Handels – und Beteiligungs GmbH” – shortly “KHB GmbH”. Big steel constructions are produced on the same site (Schutzbach – Germany) in the company “KHB Maschinenbau GmbH & Co. KG” (

All the pipe know-how was outsourced into the “Krah Pipes GmbH & Co. KG – Germany” ( – here you will find everything about application technology for pipes. So if you want to know what can be produced with our machines you will find all the information you need on this website.

About 75 employers work in the Krah group in Germany.
