Example: a 2” hose to 3” ANSI 150# PTFE Lined Flange Joint
‘Step-Up’ PTFE Lined Flange Fitting Design for Bioflex Ultra Hose

Because Bioflex Ultra Hose has better flow rates than some larger bore sizes of Convoluted PTFE hose, it represents a superior alternative when fitted with the larger size flanges in some applications.

It is, however, necessary to also “Step-Up” the PTFE-lined bore, to ensure a diameter match with the mating connector.

This is best achieved using a solid PTFE Adaptor Plate, as shown in the drawing.

Non-lined Sanitary Triclamp Fittings

Introduction

There are many different specifications, dimensions and surface finishes for triclamp fittngs. Those listed below are the popular fittings, which are stocked as standard fittings by Aflex. 

All the alternative fittings can be supplied to special order if the following information can be given;

  • Flange diameter D and Outlet diameter I
  • Hose size if known, or Aflex can recommend a hose size to suit
  • The internal Surface Finish, if it is required to be better than the ASME BPE SF3 surface finish of <0.76μm.Ra = <30μ in Ra non-electropolished.
  • Standard (see below) if known.
Standards
  • ASME BPE
  • DIN 32676 (types A, B and C are available)
  • BS 4825 Pt.3 (equivalent to ASME BPE)
  • ISO 1127
End Fitting Materials
  • Fittings in AISI 316L = EN 1.4404 = BS 316 S11
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS
  • Fittings for DIN32676 are available in 1.4435 (316L)
  • Fittings in 1.4571, Hastelloy, Monel, PVDF and other materials to special order
Temperature and Pressure Ratings
  • Pressures up to 16 Bar (230 psi)
  • Temperatures up to 120˚C (250˚F) with EPDM Gaskets
  • Temperatures up to 180˚C (356˚F) with PTFE, Silicone or Viton Gaskets
  • Higher Pressures and Temperatures with Special Clamps and Gaskets.
Internal Surface Finish Specifications
  • ASME BPE SF3 (mechanical polish, not electropolished) Surface Finish, Maximum reading:
    <0.76μm Ra = <30μ in. Ra
  • ASME BPE SF4 (mechanical polish and electropolished) Surface Finish, Maximum reading:
    <0.375μm Ra = <15μ in. Ra (SF4 is the highest level of surface finish specified in ASME BPE, and the standard, stocked fittings listed are all to this finish).
  • DIN 32676 H4 (mechanical polish, not electropolished) Surface Finish, Average reading:
    <0.4μm Ra = <16μ in. Ra. If the standard SF4 finish is not acceptable, H4 must be requested on the enquiry/order.

Note: ASME BPE Triclamp suppliers often quote an ‘Average’ of surface finish reading only, for example ‘average 15 Ra or better’, but this is not in accordance with the stricter ASME BPE requirement that a ‘Maximum’ for individual readings should be complied with.

The outlet diameters as listed are in accordance with BS4825. The ASME specification, however, requires these diameters to be 0.005” (0.125mm) less in each case. An Outlet Diameter tolerance of +0.000 -0.005” has therefore been applied, so that the same fitting satisfies requirements of both specifications.

Temperature and Pressure Ratings
  • Pressures up to 16 Bar (230 psi)
  • Temperatures up to 120˚C (250˚F) with EPDM Gaskets
  • Temperatures up to 180˚C (356˚F) with PTFE, Silicone or Viton Gaskets
  • Higher Pressures and Temperatures with Special Clamps and Gaskets.

PTFE Dip Pipe Fittings

Fixed Dip Pipes

Description

Fixed Dip Pipes are fairly rigid, thick wall PTFE tubes, either straight or 90˚ elbowed, which are directly crimped to the end of Bioflex Ultra hoses. They are designed for insertion into drums, tanks and reaction vessels in order to suction drain (or inject) process fluids transferred through the hose.

Materials
  • Standard dip pipes are in anti-static (AS) PTFE
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS
How to order

Specify the size and material of the dip pipe, whether it is straight or 90˚ elbowed. Give the length of the straight leg of the dip pipe and the length of the rest of the hose assembly separately.

Maximum Working Pressures

Dip Pipes are normally only tested to 6 Bar Pressure, and are not suitable for use at pressures higher than 3 Bar. They are usable at negative pressure up to -0.9bar vacuum.

If higher pressure ratings are required, consult Aflex Hose.

Lengths

Dip Pipes are supplied as standard in 1 metre straight lengths, but can be supplied in any length to individual requirements.

Detachable Dip Pipes

Description

As Fixed Dip Pipes above, but connected to the hose through an end fitting, not by crimping direct to the hose.

Design

A straight, or 90˚ elbowed anti-static PTFE Dip Pipe, fitted with a Flange or Cam & Groove Male PTFE Lined & Flared end fitting.

The most usual end fitting is a Cam Male (as shown), so the dip pipe can then be connected to a hose with a Cam Female end fitting.

Non-Lined 90° Elbow Fittings

A 90˚ elbow attached to the hose can be supplied non-PTFE lined, as shown, for any size or grade of hose or type of fittings, to special order.

 

3-A Sanitary Fittings

3-A Sanitary standards require the hose end fitting to be sealed against the ingress of external fluid into the fitting construction. Aflex Hose have implemented a silicone seal between the ferrule and fi tting to address this requirement. Standard Bioflex Ultra fittings are not available with the 3-A seal feature and therefore a different fitting type is required.

When ordering customers should specify that the hose assembly must meet 3-A sanitary requirements. The 3-A symbol and appropriate marking to 3-A requirements will be applied to the hose assembly.

Note that 3-A hose assemblies have slightly reduced MWP and these are tabulated separately within this section.

Bioflex Ultra Silicone Cover hoses are soakable.

The Aflex Hose 3-A certificate is available to view on our website in the 'certifications' section. The Aflex Hose 3-A certificate is also available to view on the 3-A Sanitary website .  Follow the link to the database search page and search for “Aflex Hose” under view company listings.
