The selection, design, and location of piping supports is an essential part in the study of any industrial process installation. Typically, piping is supported at regular intervals on steel supports embedded in concrete foundations or directly on steel structures. The distance between supports is the span. The allowable spans between supports of horizontal lines are […]
Most industrial plants have some underground piping systems, in other words located below the standard elevation of the ground defined in the plant. In most cases, these piping systems are installed during the construction of the new plant, and are rarely thought about until a problem arises. An underground pipe is not the same as […]
Vibration is one of the major causes of failure in piping systems connected to turbomachinery equipment. Piping systems are subjected to excessive vibration levels whenever the mechanical natural frequency of the system is excited by a pulsation or by a mechanical source. If the frequency of the load excitation is the same or in the […]
Within the family of non-metallic pipes there are different types used in the industry: GRP (Reinforced Fiberglass), PVC, PP (Polypropylene), HDPE (High Density Polyethylene) among others. This type of systems are usually used in industrial plants in general, petrochemical plants, water treatment plants, sea water desalination plants and in power generation plants. One of the […]
When a change is identified during construction, a lot of effort is put into identifying the impact of the change for cost, schedule, engineering/design and materials, and then having the change order approved. Change is always disruptive during construction. The crew has to stop what they are working on, make the existing area safe, and […]
The word “cryogenics” comes from two Greek words, “kryos” meaning icy cold, and “genes” meaning to form. The term cryogenics was first used in 1875 and has come into general usage since 1955. Cryogenic temperatures are normally considered as below (-)100ºC. One of the major benefits of handling gases in liquefied form is the enormous […]
