PB Pipe

Junxing has been manufacturing heating and sanitary pipes from polybutylene for more than 10 years. Our wealth of practical experience in processing and using these pipes shows that polybutylene is one of the best materials for heating and sanitary applications. A high degree of flexibility, excellent thermal stability, low creep and high long-time rupture stress are typical properties of these materials.
