Equipment for smooth pressure pipes of PEHD
Smooth pressure PEHD pipes from d 16 up to d 630 mm with the trade-mark Plastec are produced by the most up-to-date extrusion lines from the European leaders “Krauss Maffei” and “Cincinnati Extrusion”. All steps of the production process are continuously monitored and controlled.
Precise devices for feeding and dosing the raw materials ensure a constantly stream of granulate to the extruders depending on the size and the parameters of the pipe in production.
Marking the pipes by using the "hot stamp" method guarantees durability of the inscription as long as the life expectancy of the pipe.
Modern roll up devices allow the delivery of the pipes in rolls of 100 m for diameters from d 20 up to d 110 mm, as well as on drums for bigger pipe lengths.
The constant maintaining of the production parameters combined with the inner-built quality control system enables us:
- to correct even the smallest departure from the norm before reaching its allowable level.
- to guarantee perfect quality of the production
- to offer longer exploitation period of our pipes in compliance with the requirements of European and world standards.
Equipment for corrugated double wall pipes
Double-wall corrugated pipes with the trade mark GOFRI made of polyethylene (PE) or polypropylene (PP) are produced on a last generation blow moulding corrugator line from the European leader “Fraenkische Rohrwerke”,Germany.
The unique structure of the pipe as a combination of outer corrugated and inner smooth surfaces unifies the advantages of an extremely high static resistance of the corrugated surface with the very high hydraulic ability of the inner smooth surface.
The specific technology of this kind of equipment allows the production of corrugated double-wall pipes with diameters from DN 110 mm up to DN 800 mm to inside diameters DN/ID 150, 200, 250, 300, 400, 500 and 600 mm, as well as to outside diameeters DN/OD 110, 125, 160, 200, 315 mm. The pipes are produced with a pipe length of 6 m, and diameters DN/OD 110, 125, 160 and 200 mm as cable-protective pipes can be produced also on rolls of 25 or 50 m.
Another special development is the production of IN-LINE coupling, that means belling of the pipe directly during the production process. The integrated coupling presents a final product of a pipe with a connecting element – coupling, and offers a guarantee for a more effective, economical and reliable installation.
The new products are specially developed to fulfill the needs for:
- Sewage pipes (
and 
system) - Drainage pipes (
system) - Cable–protective pipes (
system)
The product was awarded with a Golden medal and diploma on the International Technical Fair in Plovdiv 2005.
Equipment for irrigation pipes of PEHD
The production of drip irrigation PE pipes with built–in drippers is the newest investment of the company.
is a pipe with built–in PE drippers used to distribute water in drop form at a given rate.
It is manufactured under the licence of DRTS through extrusion of polyethylene low density (LDPE) and linear polyethylene low density (LLDPE).
The dripper is enclosed and in separable welded to the inside wall of the tubing as it is extruded in the manufacturing process. This result in a one-piece, joint-less dripper-enclosed drip lines which can be laid out in the field, rolled up, stored and re-used again and again. The drippers can't be removed or separated from the joint less tubing due to water pressure or handling.
This kind of pipe is lighter, stronger and more flexible. It offers guarantees of a long working life and requires no special maintenance.
eliminates the disadvantages of similar products as it offers a really economical method for irrigation of all types of vegetable or flower crops.
The product was awarded with a Golden medal and diploma on the International Technical Fair in Plovdiv 2006.
Equipment for sewage pipes up to 1200 mm
The innovative technology for the production of PЕ pipes bigger diameters up to DN 1200 mm is presented by the method of profile extrusion and its spiral winding and welding into a pipe. The production line consists of an extrusion line and a special square installed to the extrusion line machine for spiral winding and forming the final pipe.
The special technique allows the production of pipes with the trade mark 
with dimensions from DN 500 up to DN 1200 mm on inside and outside diameter, and the ring stiffness classes SN 4 and SN 8.
pipe has smooth inner and outer surfaces in black color.
The main fields of application of pipe are as sewage pipe for industrial and domestic areas, as well as for the leading of rain water.
