Right angled steam strainer

Series E G 042/043

Right angled steam strainers with cylindrical strainer inserts are mainly used in power plants. The design enables a 90° elbows to be replaced. Retrofitting power plant renovations, expansions or modernizations is also easy to carry out thanks to this type of construction. The installation position, the space-saving service room and a welded construction that meets all power plant requirements are the basis of this design. Construction, strength calculation, materials, certificates, welding qualifications and expert non-destructive tests and approvals are part of the service.

A cylindrical sieve is inserted into a housing consisting of a T-piece with a reduced branch, a concentric reducer and a service opening (blind flange). Due to the axial inlet side, the current impulse on the screen surface is avoided. The sieve surface is flowed through evenly, without a cross-section narrowing in the annular space or in the deflection. The sieve can be optimally sealed, fitted from the lid side, and maintain the desired filter fineness without any gaps.

A free filter surface, up to 5 times larger than the cross-section of the inlet nozzle, offers the lowest pressure loss and, at the same time, a high level of protection against bursting on the sieve.

Low pressure loss, long service life, high availability and a robust construction for the operating conditions in the power plant are the key data of the design. No complex flow guidance is required inside the housing. Value is placed on a simple construction principle with the lowest possible resistance. This design guarantees a low pressure loss in a clean condition even at high flow speeds and thus a long service life until it is contaminated.
