• Pipe-joining methods

  Steel pipe should be welded, except for joints which need to be taken apart for service, which will be flanged. It is essential that welding is carried out by competent craftsmen and is subject to stringent inspection.Flanges for ammonia (and preferably, also, for other refrigerants) must be of the

• What is Hot Dipped Galv.Seamless Steel Pipes

  Hot dipped galv.seamless steel pipe is a steel pipe coated with a layer of zinc on the surface. The molten metal reacts with the substrate to form an alloy layer, so that the coating and the substrate are firmly bonded, and the thickness of the coating is uniform. It also has good corrosion resistance due to its galvanized coating.

• Advantages of Pre-galvanized Steel Pipe

  Pre-galvanized steel pipe is one of the most common and popular types of pipe today, made of solid steel with an additional zinc coating. The role of the zinc coating is to prevent the steel pipe from rusting and corroding. Since the pre-galvanized steel pipe does not rust or corrode, the pipe will

• HEAT TREATMENT OF PIPES III

  If a weld is allowed to cool prior to the postweld heat treatment, the rate of uniform cooling must be controlled to prevent a detrimental effect in the piping.Partial heat treatment of a piping assembly that cannot be fitted completely into a furnace is acceptable if there is at least a 300 mm (1 f
