Startup Strainers Piping
Some companies require full thread engagement when installing piping and the extra 1 8 can be added to the bolt size.
Startup strainers piping. It is not designed to be a permanent fixture in the piping system. Permanent strainers may be installed upstream of control valves traps and instrutments to protect them from. Delta manufactures all types of strainers inline strainers startup strainers witches hat strainers per customers specifications. Installation of a conical strainer can be done in one of two different ways cone facing upstream or cone facing downstream.
Temporary strainers are usually mounted in a pipe spool between two flanges and are ideal for situations where space restrictions are an important consideration. If the application requires a more permanent fixture a basket strainer should be installed. Temporary strainer temporary strainer is a startup strainer also known as conical strainer or basket strainer and is installed in a system to remove unwanted debris from the process stream. Inline strainers some referred to as witches hat strainers are designed to remove debris from fluids in piping systems typically during startup.
Installation of a spool piece equal or more than the length of the strainer is recommended for ease of installation or removal. They are available in carbon steel stainless steel and other alloys depending on the needs of the application. Strainers are important components of piping systems to protect equipment from potential damage due to dirt and other particles that may be carried by the process fluid. Installation of a spool piece equal or more than the length of the strainer is recommended for ease of installation or removal.
Their are three types of temporary straineres cone truncated cone and flat. The figures here below depicts typical start up strainers. There are three basic configurations of temporary strainers namely the conical type the basket type and the plate type. It is used for piping start up applications only it accomplishes straining by directing the fluid through sized openings in the strainer.
Piping engineering piping materials piping fittings piping strainers conical strainers where used. Winston royal guard s type 50 p cone strainers and type 51 p basket strainers commonly called startup strainers or temporary strainers are furnished extensively for use in new piping installations to catch such things as weld slag pipe scale and other unwanted solids. The addition of a start up strainer can add 1 8 to the length of the bolts. Strainers are typically used in temporary service.
During system start up and flushing strainers may be placed upstream of pumps to protect them from construction debris that may have been left in the pipe. They are normally used during the initial startup of a new application such as a pump. It is inserted between two flanges in the pipeline up stream of the equipment to be protected. The strainer is usually installed between a set of flanges for an initial period after a new plant has been installed.
After startup and the debris has been collected by the strainer it is usually removed. Temporary strainers are designed for protection of equipment and instrumentation during start up periods. Temporary strainers are designed for protection of equipment and instrumentation during start up periods. A standard start up strainer has 1 8 perforation with 150 length.
However many times after initial cleaning the temporary strainers are placed back in service for permanent protection of equipment.
