Working Conditions

Specific gravity was 1.510-1.550 kg/l, pressure 2 Bar (maximum 3-4 Bar), temperature of 99°C. Chemical composition: Na2O, AI2O3, F32O3, SiO2, CaO. Flow rate: 180M3/H.

Pexgol Pipes

160 mm class 15 (SDR 11).

Application

Industrial.

Lenght

15 meters with flared ends

The Challenge

The main challenges were corrosion and scaling formation on the inner surface of existing steel pipes, causing a decrease of inner diameter of the pipes and consequent decrease of their throughput ability.

Pexgol Solution

Replacement of the existing 159 mm steel pipe with a 160 mm class 15 (SDR 11) Pexgol pipe.

The test line consists of three parts: One section is a white G-Pex pipe manufactured in Moscow, approximately 12 m long. Two more sections are 0.5 m long, each of black Pexgol pipe with flared ends, manufactured in Golan Plastic Products, Israel. These sections were connected by Plasson’s

Electro-fusion Pex-2-Pex couplers. During the entire operation the pipe was under continuous vibration because of a grinder operation.

The pipe was installed by the field team of Polimerteplo Group Llc accompanied by the field installation engineer of Gloan Plastic Products Ltd.
