1665 results about "Pipe support" patented technology

A pipe support or pipe hanger is a designed element that transfer the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation. The four main functions of a pipe support are to anchor, guide, absorb shock, and support a specified load. Pipe supports used in high or low temperature applications may contain insulation materials. The overall design configuration of a pipe support assembly is dependent on the loading and operating conditions.

Non-stand construction method for large bridge arch rib

The invention relates to a large-scale bridge (steel pipe concrete arch bridge) arch rib non-support construction method, which is characterized in that: the fastening tower process and hanging tower process are combined; the fastening anchor process and hanging anchor process are combined; rubber support is applied in the tower articulation (steel structure); steel twisted wire is used as the fastening-hanging tower -anti-wind rope (tower pressing cable); centralized working surfaces and steel twisted wires are adopted in the fastening-hanging process; steel pipe support are used in tower; and less fastening cables are used in the fastening-hanging process.
