Pipe characteristics

The integrity of the connection

The quality of the piping depends on the connection. PEC PIPE selects various bonding methods based on the site conditions, such as electric fusing sheet, fusing, screw tightening, flange, electronic socket (E / F), and therefore, we can completely exclude the possibility of leaking

Convenient construction

PEC PIPE is equipped with a variety of joint pipes and simple welding equipment, so that even the unskilled workers can easily weld them

Flexibility

The flexibility of the material itself is excellent, so it is easy to construct the piping without being restricted by the geographical or environmental conditions. It is relatively safe not only for earthquakes or subsidence but also has excellent elasticity for recovery

Chemical resistance

Polyethylene does not corrode acid, alkali, salt, etc., and it is safe from various erosive materials because of lack of spread of seaweeds and bacteria.

Economics

PEC gas pipes are cheaper than other types of materials and cost of maintenance such as defect repair costs is low

Lightweight

PEC water pipes are only 1/7 of the weight of steel pipes, so they are easy to handle and easy to install.

Impact resistance

The PEC gas pipe is excellent in resistance to external impact due to the nature of the material. Leakage of pipes and joints does not occur even after earthquake or subsidence
