The correct use of pressure piping

The reliability of a pressure pipe depends, first and foremost, on the quality of its design, manufacture and installation. In the use of pressure pipelines due to media and environmental damage, improper operation, poor maintenance, often lead to deterioration of material performance, failure and reduce its performance and cycle, or even accidents. The safety and reliability of the pressure pipeline is greatly related to the correct use. Only by strengthening the control process operation index and process discipline, insisting on the post card responsibility system and carrying out the inspection tour in earnest, can the pressure pipeline be used safely.

Process indicators include: control of operating pressure and temperature control of alternating loads and control of corrosive media content.

The post responsibility system includes: the operator is required to be familiar with the technical characteristics, system structure, technological process, process index, possible accidents and measures to be taken; the operator must pass the safety technology and post operation law study and training, After passing the examination, they can carry on the operation independently; during the operation, the operator should strictly control the process index, operate correctly, strictly prohibit overpressure, over-temperature running.

Inspection tour includes: the use of units should be based on the unit process units and the distribution of units divided by the region, clear responsibilities, to develop a strict pressure pipeline inspection system. System to clear the inspectors, check the time, check the site, should check the project, operators and maintenance personnel should be in accordance with their respective responsibilities and requirements on a regular basis to complete inspection routes to each site, each project inspection and make Tour inspection records.

Pressure pipe systems

Since the mid-1950s, various types of polyethylene have been used to manufacture pressure pipe systems, starting with relatively small diameter water pipes. Over time, modern polyethylene PE80 and PE100 grades were developed, whilst the use of polyethylene continued to grow into a range of applications that now includes:

  • Water and gas distribution networks
  • Water transmission pipelines
  • Sewage and drainage pipelines
  • Various types of outfall and intake pipelines
  • The lining of new and existing pipelines
  • A variety of industrial applications including oil and gas, mining slurry and cooling water pipelines

Developments in material and production technologies have allowed pipe manufacturers to produce ever larger diameter pipes. Today, international standards cover pipes of up to 2,000 mm OD (Outside Diameter), with a number of manufacturers being able to produce even larger pipes.
