Description
SteelFlow CCA basket strainers retain the solids in the line in a stainless steel basket, made of perforated plate or mesh, that is removed through the cover, washed and put back in place. The liquid enters through the side flange, flows through the basket from the inside out and leaves through the opposite flange: the solids stay inside the basket.
The vessel is made of carbon steel—SA-516 Gr. 70 plate, SA-106 Gr. B pipe and SA-105 flanges—and is designed to ASME VIII Division 1 for the pressure, flow rate and connection of each process: 4″ to 36″ bodies, 2″ to 24″ ANSI B16.5 flanges in class #150, #300 or #600, and design pressures from 3 to 104 kg/cm². The cover can be bolted with a davit, quick-opening or with swing bolts.
Each unit ships with its data book: drawing, design calculations, material certificates, welding procedure and welder qualifications, radiography and hydrostatic test. We manufacture them at our metal fabrication plant in Argentina. If the fluid also needs fine filtration, the basket protects the liquid filter housing installed downstream.
Protects the equipment in the line
Retains solids ahead of pumps, heat exchangers, instruments and cartridge or bag filters.
Washable, reusable basket
It is removed, washed and put back in place: no disposable elements. With a spare basket, it is washed offline.
Three closure types
Bolted cover with davit, quick-opening or swing bolts: the basket comes out without dismantling the piping.
Differential pressure cleaning
Taps for gauges or a ΔP transmitter: rising differential pressure shows when to clean the basket.
4″ to 36″ bodies
2″ to 24″ ANSI B16.5 flanges, class #150, #300 or #600, with the basket area sized for low pressure drop.
ASME design with data book
ASME VIII Division 1, with design calculations, radiography and hydrostatic test documented for each unit.

Frequently asked questions
What retention can I order?
3 to 10 mm perforated plate, or 12 to 900 µm mesh supported on perforated plate, in AISI 304, 316 or 316L stainless steel. It is selected according to the size of the solids and what the downstream equipment needs.
How is it cleaned?
When the differential pressure reaches the cleaning value, the unit is isolated and drained, the cover is opened and the basket is removed with the solids inside. It is washed and put back in place; with a spare basket, the dirty one is washed offline.
Which closure should I choose?
There are three: bolted cover with davit (K); vertical quick-opening closure (R), with less downtime at each cleaning; and swing-bolt cover with a hinged arm (F), which opens without removing the bolts.
What information do you need for a quote?
Normal and maximum flow rate, fluid and viscosity, size and load of solids, operating and design pressure and temperature, line connections (Ø, class and flange type), and the painting and inspection specification.
