• 
• RCF NORSOK NCF5 Series

• RCF Advantage
  • Space saving
    • Weight saving up to 70%~80% than ANSI flanges
  • Double Independent Seals make it er
    • Positive sealing method
  • Integrated sealing system (both inside and outside)
    • Larger range in design temperature and pressure
• RCF Working Principle
  • The RCF compact flange design principle is that the flange face includes two independent seals. The first seal is created by application of seal seating stress at the flange heel. The main seal is the IX seal ring. The seal ring force is provided by the elastic stored energy in the stressed seal ring. Any heel leakage will give internal pressure acting on the seal ring inside intensifying the sealing action.

• RCF Size and Pressure Rating
  • 1/2”~48” in size and Class 150# to 2500# in pressure rating.
  • Bigger size and higher pressure rating on request.
• RCF Materials
  • ASTM A105, A350 LF2, LF6, A694 F52~F70
  • AISI 4130, AISI 8630
  • A182 F316/316L, F51, F53, F55, Inconel 625, Incoloy 825.
  • Other material on request
• RCF Gasket
• • RCF IX seal ring, axial forces are exerted on the taper of the metal seal ring and translated into a radial sealing force. Furthermore with increased pre-load, the bevel is closed and face to face contact is achieved at the outer wedge while most of the bolt pre-load is transferred as compressive forces between the flange faces at the heel.
• RCF Design and Verification
• • BOYUE Steel provides calculation service based on ASME section VIII Division 1, 2 and 3. Also we have ANSYS software engineers to do the analysis and design verification

BOYUE GROUP are professional for "Tubesheet " for “Shell & Tube Heat Exchanger” application, we are available in many shapes, sizes and have been used in industry for over 20 years. In our group we are various sub design types: Fixed, U-tube and Floating tubesheet. Variations of all can be denoted as type “E”, “F”, “G”, “H”, “J”, “K” or “X”.

The main applications are where high pressure/temperatures are key considerations. Loosely, general designs consist of the/an outer shell in which resides a tube bundle (these can be configured as finned, plain etc) sealed at each end by a tube sheet which isolates the tubes and the outer shell. Shell & tube heat exchangers have the capability to transfer large amounts of heat at low(er) costs.

This, in principle, down to both design simplicity and effectiveness – large tube surface for reduced weight, volume of liquid and importantly floor space. Whilst there is a wide variety to choose from there are certain key components similar in all. Tubesheets have tubes attached to them within the body or “shell” of the heat exchanger. The tubes allow the movement of a given medium (gas/fluid) through the shell chamber stopping it mixing with a second fluid medium that lies outside these tubes.

As long as there is a temperature difference between these, in effect, the two flow past one another exchanging heat without ever mixing. Tubesheets can be fixed or floating dependent on the application the heat exchanger is designed for.Tubesheets are a critical component of the final design. There are a multitude of materials they can be manufactured from. Material selection is made after careful consideration as it is in contact with both fluids. It must therefore have the necessary corrosion resistance, electromechanical and metallurgical properties associated for its given working environment.The tubesheets themselves contain holes drilled into them.

This, in a given, very specific design configuration, at very precise locations with critical tolerances. The amounts of holes can range from a few to thousands. These pattern or “pitch” holes are relative to each other tubesheet within the shell. This pitch changes tube distance, angle and flow direction. These parameters have been varied to maximize the heat transfer effectiveness.

Because these tubesheets are the main, critical, internal components BOYUE GROUP manufactures directly to OEM drawings issued files.

BOYUE GROUP considerable experience in this highly specialized area means that whatever the requirement, whatever the timescale, we have the technical, in house experience and know-how to approach a given task, deliver on time and in budget. This is why the company is entrusted to manufacture to key, blue chip clients across the globe.
