Where is Ctube’s PVC Pipe produced?
According to the customers we serve, the length of most customer requirements is as follows: 3 Meters (9.84 ft) 6 Meters (19.69 ft) 12 Meters (39.37 ft, only for special project) Reasonable length is convenient for long-distance transportation and installation. Normally, electrical pipes are loaded in containers when they are shipped abroad, and then delivered by sea. Even short-distance transportation requires the use of trucks. If it is too long, it is not easy to load and accidents are prone to occur. In addition, shorter pipes are also easy to install, because we also need multiple pipes in most cases during installation.
