Benefits of PE 80 / PE 100 pipe systems

Weltplastgas® PE100/PE80 piping systems for the distribution of natural gas have many advantages compared to conventional systems:
high resistance to environmental stress cracking
long-term stability of crack growth
high fexibility, toughness as well as low weight and impact resistance
high flexibility at low temperatures (-50 ° C)
high resistance to external abrasion
excellent flexibility and resistance to movement of soil due to earthquake
high smoothness of the interior walls with very small flow losses
high chemical resistance to aggressive media

Weltplastgas® PE100/PE80 tubes have a number of very important features:
have a high inertia on the chemical composition of natural gas
high hardness materials reduces the risk of external damage to the pipe wall
resistant to the growth of fungi and mold
may be connected by welding, electricfusis, mechanical joints
welding places have the same mechanical strength and toughness as the pipes itself

Weltplastgas® PE100/PE80 piping systems for gas distribution - competitive price and high reliability of investment:
small mass of tubes suitable for low cost transportation
the simple manipulation of the tubes on the ground during installation without the necessity for heavy equipment
connecting by electrofusion welding and fasteners ensures high reliability of weld with low cost and highly competitive long-term maintenance
flexibility of taking on uneven grounds lowers maintenance costs, and excavation
easy and quick replacement of possibly damaged parts of the pipeline
very low flow losses reduce distribution costs of natural gas pipeline system

PE100/PE80 – life in service
Weltplastgas® PE100/PE80 piping systems are designed for a lifetime of at least 50 years. Previous experience in the use of HDPE for pressure piping gas from the sixties have shown excellent durability.

Weltplastgas® PE100/PE80 – quality control:
Weltplastgas® PE100/PE80 pipes fully meet the standards series EN ISO 1555 and 4437, due to requirements specification and control of individual properties as well as because of the input of raw materials, production processes and final control. Control procedures are implemented in accordance with established quality management system ISO 9001:2000.


download-weltplastgas_engFor production of Weltplastgas® PE100/PE80 tubes, raw world's top producers of high-density polyethylene are used. Pipe extrusion production process is fully automated, without the possibility of human error.

During the extrusion of the tube ultrasonic thickness control is carried out with minimal outstandings. Weltplastgas® PE100/PE80 pipe control is carried out in our own control laboratory starting from incoming raw materials PE100/PE80 with process control and final control of finished products - pipes. Continuous laboratory control of short and long-term hydrostatic strenght, size and rheological properties provides a high reliability of the quality of pipe in the distribution of natural gas

Quality Control Weltplastgas® PE100 / PE80 tube was controlled by an external certified laboratories and certified institutions, OFI, Austria.

Weltplastgas® PE100/PE80 – ecological facts:
Weltplastgas® PE100/PE80 piping systems are environmentally friendly, totally inert from the standpoint of waste disposal, materially recycled. Weltplastgas® PE100/PE80  piping systems are not biologically degraded, do not support the growth of mold and fungi. From the standpoint of toxicity no knowledge about any aspect of traces of toxicity in the application of  Weltplastgas® PE100/PE80 pipe systems for transportation of natural gas.

Connection mode

Weltplastgas® tubes are connected by the electro-fusion welding fittings made by the world famous manufacturer which provides complete installation of piping gas pipeline system.
