Fluid Catalytic Cracking Unit (FCCU)
Hidroflex Indonesia has successfully engineered and produced twenty expansion joints for Nigerian oil refineries (Dangote Industry Limited).
It is currently installed in the refinery’s catalytic cracking fluid (FCCU) unit.
Metal Expansion Joints or Bellows are used to accommodate the movement of pressurized piping system caused by thermal growth, contraction and small vibrations. All Expansion joints are designed to EJMA 9 or ASME as required. These bellows are used to carry various media, including steam, emission gases, water, acid, alkalis and hydrocarbons.
These are normally used in large hot air or gas off-take ducting. These joints can be supplied in almost any size with single miter corners, double miter corners, rounded corners, or continuous joint with no weld in the corners. Rectangular joints can be manufactured and supplied in Stainless steel, Alloy steel to handle temperature up to 1000 degrees C.
Mitered Corners | Weldless Radiused Corners
These thick (heavy) wall stainless steel or carbon steel expansion joints for Recuperators, Sulphuric Acid plants, Heat exchanger and Calciners can be assembled and supplied with up to 400mm convolution height and 40mm thickness. These are designed to TEMA 8 or 9 and we can also offer FEA analysis as required by TEMA 9. We can also supply Concentric Cone, Bellmouth, Fan Ring, Diffuser and Kort Nozzle.
This hose is ideal for absorbing vibration, misalignment, piping expansion or contraction and equipment motion. We supply these hoses in corrugated stainless steel or PTFE with smooth or corrugated bore, single or double braided for high pressure and temperature application.
