Y-Strainers - Rolls-Royce Holdings

1 PRODUCT OFFERING. Y-Strainers MECHANICAL SYSTEMS AND COMPONENT ENGINEERING. In specific types of nuclear power stations, Advantages to using Y-Strainers Y-Strainers are located in nuclear and waste compact: fits easily in-line process systems. They are used in relatively well suited to nuclear and waste process systems where other system components require protection from active clean process streams to remove particulate contamination matter from process fluid. This is necessary filter basket can be tailored to alter system pressure drop or to in almost all process streams to protect change acceptable screen size change of filter basket can be completed without costly delay other components (pumps, filters, valves, direction of flow is radially outward from the basket interior to etc) from damage or contamination that the basket exterior, resulting in the entrapment of particulate could result in expensive replacement costs on the inside wall of the basket.

2 And downtime. Rolls-Royce Y-Strainers The process fluid enters the Y-Strainer and passes into the interior of a cylindrical screen (basket). The fluid passes through the screen and all can be produced in a variety of materials and pressure ratings to particulate larger than the screen mesh is trapped in the screen. This meet strict leak-tightness requirements is particularly beneficial immediately after start-up, when assembly of are available in a variety of screen mesh sizes the system may have created a large quantity of particulate (weld burrs, are available in any style of end connection (butt-weld, socket fragments, dust particles, etc).)

3 Weld, flange, etc). the filter basket is positively sealed to the body by means of o-rings, thus ensuring better particle retention and a reliable seal NUCLEAR INNOVATION & TECHNOLOGY. Y-Strainers Applications Design documentation available The following are typical applications: pressure rupturing capacity downstream of ion exchange columns to ensure migration of pressure drop at rated flow resin does not occur seismic qualification upstream of flame arrestors to ensure flame arrestor elements installation, operation and maintenance instructions do not clog with particulate matter upstream of valves to prevent clogging of valve spools Compliance to codes and standards ASME Section III, Division 1, Class 3.

4 Features CAN unique basket design allows for higher flows at rated pressure drops ANSI - reinforced media support provides higher particulate holding CAN capacity CAN double sides support for strainer media maintains basket integrity in the presence of reverse flow ASME NQA-1. wide range of retention sizes available Key point of contact many pre-engineered, pre-registered designs available Technical Sales Tel: +1 705 743 2708.
