Piping The ASME B31.3 standards specifies the minimum requirements for materials, design, fabrication, testing, and inspection of process piping systems. The code covers a wide range of topics, including design pressure and temperature, pipe sizing, wall thickness, materials, flanges, fittings, valves, expansion joints, supports, testing, and inspection. ASME B31.3 Piping standards The code specifies the design … Read more
Check valve are installed in pipelines to allow flow in one direction only. Check valve are also called non return valve. It is operated entirely by reaction to the line fluid and therefore do not require any external actuation. Types including lift, disc, swing and wafer check valves. What is function A check valve is allows fluid … Read more
ASME standard ASME stands for the American Society of Mechanical Engineers. It’s a professional organization that develops consensus technical standards—practical, detailed rules engineers and manufacturers use to design, build, inspect, and operate mechanical equipment safely and reliably. An ASME standard (often called a code) tells you things like: how thick a pressure vessel wall must … Read more
Intrusive Pig Signaller:- Once a pig has been inserted into a pipe system, its position cannot be visually confirmed directly. A system is therefore required to indicate a pig’s position continuously or intermittently at pre-determined points in the pipeline. Continuous detection is called pig tracking, while intermittent detection is called pig signalling. Each method involves … Read more
A stuffing box used for shaft sealing may be one employing gland packing or using mechanical seals. Easily replaceable without opening the whole pump, gland packing give stiff competition to mechanical seals, but the packings have to be carefully selected to be successful. Gland Packing Gland packing is used extensively for the sealing and restriction … Read more
Documents required for equipment layout:-The primary consideration in arrangement of equipment’s shall be to provide an economical Facility with good weight distribution, minimum lift weight, safe and easy to operate and maintain. 1. All piping components requiring operation or maintenance where practical, shall be Located where they can be operated, serviced conveniently. Access shall be … Read more
A swing spool is a removable section of piping that is used to connect two different pipes or to change the direction of flow in a piping system. Swing spools are typically made of steel or stainless steel, and they can be flanged or welded to the pipes. Swing spool is used to change the … Read more
HIPPS valves are used as the final part of an instrumented system intended to prevent an unacceptably high pressure occurring in downstream equipment. They are always arranged to fail closed and spring/hydraulic actuators are usually the only practical alternative for operation. HIPPS valves are called High Integrity Pressure Protection System (HIPPS) valves In general, closure … Read more
A deluge system is normally the main firefighting system on any offshore installation, used to protect process-areas, drilling-areas and other high-risk areas. A Deluge system is normally an automatic system, which is triggered by a fire detector in the protected area, and which is using water as the extinguishing agent. How piping of deluge system … Read more
Insulating gasket are designed to prevent galvanic corrosion between flanges of dissimilar metals, for example a carbon steel flange bolted to a stainless steel flange. A conducting liquid such as water must be present between the two flanges for galvanic corrosion to occur. On oil and dry gas duties, insulating gaskets are not required. Because … Read more
