A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through ...
Journeyman pipefitters deal with industrial/commercial/marine piping and heating/cooling systems. Typical industrial process pipe is under high pressure, which requires metals such as carbon steel, stainless steel, and many different alloy metals fused together through precise cutting, threading, grooving, bending, and welding.
It develops, manufactures and markets RTP, which is a flexible high pressure pipe. It is supplied in long length coils of up to 400m length and has design pressure ratings from 36 to 450 bar. This type of pipe is typically used in the oil and gas industry for oil and gas flowlines, high pressure water injection and water transportation lines.
Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper, [34] brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes [35]), or other nontoxic material.
Underground piping systems for landscaping drainage or the disposal of stormwater or groundwater also use low-pressure gravity flow, so fittings for these systems resemble larger-scale DWV fittings. With high peak-flow volumes, the design and construction of these systems may resemble those of storm sewers .
External high-pressure fuel delivery lines between the high-pressure fuel pumps and fuel injectors shall be protected with a jacketed piping system capable of containing fuel from a high-pressure line failure. A jacketed pipe incorporates an outer pipe into which the high-pressure fuel pipe is placed, forming a permanent assembly.
