3-A Sanitary fittings

3-A Sanitary fittings

3a logo

3-A Sanitary Standards requires the hose end fitting to be sealed against the ingress of external fluid into the fitting construction. Aflex Hose has implemented a silicone seal between the ferrule and fitting to address this requirement.

The direct crimp style fitting does not incorporate the silicone seal as standard and a modified version of the fitting for 3-A 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.

Bioflex Ultra covered hoses are soakable in both standard and 3-A sanitary configurations. The 3-A assembly is only available with an EPDM or silicone cover.

The Aflex Hose 3-A certificate is available to view in our website literature 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.

Notes: For integral PTFE-lined fittings only

  • FEP gaskets require higher clamping forces to flatten the seal and make the joint. This is made easier by “pre-setting” these gaskets by clamping polypropylene cam male inserts to the assembled fittings, which must then be kept in place during storage, until use.
  • Any Customer’s own “special” gaskets must be pre-supplied to Aflex for special assembly and testing of hose assemblies, to ensure suitability.

PTFE dip pipe fittings

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 one metre straight lengths, but can be supplied in any length to individual requirements.

Detachable dip pipes
fixed dip pipe 90 elbow

Description

As fixed dip pipes. 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 and groove male PTFE-lined and 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.

ENCAP end fittings

ENCAP end fittings

PTFE encapsulated (Encap) end fittings

  • Easy to assemble - fully PTFE-lined end fitting - larger bore than conventional PFA Encap fittings
Introduction

In response to requests from customers Aflex have developed a basic range of PTFE encapsulated end fittings.

These can be used in place of standard non-lined end fittings to provide a PTFE-lined alternative for threaded end fitting types where integral lining is not possible. They also provide a cost-effective alternative to exotic metals such as hastelloy where high levels of chemical resistance are required.

Encap fittings do not provide the same advantages as integral lined fittings. The full hose bore size through the fitting is reduced and entrapment areas are present at the end of the encapsulated hose tail.

Encap fittings provide a fully PTFE-lined fitting with a flared face, which is easier to assemble. The Aflex Encap fitting design has a significantly larger bore than the conventional PFA encapsulated fittings available from other suppliers.

Construction and application


Encap fittings are assembled and crimped using the same non-lined ferrules, crimp diameters and assembly procedures that are used with standard direct crimp fittings throughout the Aflex PTFE hose product range.

The PTFE encapsulation is either natural or antistatic PTFE as required, with a PTFE wall thickness of 1.5mm (0.060”) for sizes up to 1¹/2” and 1.8mm (0.070”) for sizes 2” and above.

Encapsulated fittings are available for all Corroline+ Self Assembly Distributors.

Important Note: The use of Encap fittings with hoses, ferrules or other components which are not all supplied by Aflex Hose is strictly prohibited and no liability will be accepted for any failures resulting from such abuse.

Introduction

There are many different specifications, dimensions and surface finishes for triclamp fittings. 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.

Mini sanitary triclamp fitting

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.

Introduction

Advantages are unrestricted clean flow of fluids, no fluid entrapment areas, and all PTFE wetted surfaces internally. Available as standard, stocked fittings in the listed sizes, or in other sizes to special order.

End fitting specifications

  • ASME BPE
  • DIN32676
  • BS4825 Pt 3 - equivalent to ASME BPE
  • ISO 1127

End fitting materials

  • Fittings in Grade 316L SS (= BS 316 S11 = EN 1.4404)
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS

Note: The inside lip of the Aflex flared face design is hot formed to a square edge. This prevents a gap for fluid entrapment between the rubber seal and the sealing face. Other suppliers designs have rounded edges, which opens a gap for fluid entrapment.

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

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.

Flange specifications

  • ANSI B16.5 (also ASME B16.5) Class 150# and 300#
  • *DIN PN10, PN16 and PN40
  • JIS 10K
  • Other pressure ratings and flange specifications are also available.

*DIN PN10, PN16 and PN40 Flanges all have the same dimensions, and so are fully interchangeable

End fitting materials

  • Flanges normally in Grade 304 SS, or Grade 316 SS if required
  • Flange Retainers in Grade 316L SS
  • Ferrules, most in Grade 304 SS, some sizes in Grade 316 SS

Surface finish

  • All surface finishes are to ASME BPE-SF-O (no finish required).
  • If a specified finish on a particular surface is required, please state on the enquiry and order.

Alternative options for flange component only:

Zinc plated carbon steel

Maximum pressure ratings

  • ANSI 150# = 16 bar (230 psi),
  • ANSI 300# = 41.4 bar (600 psi)
  • DIN PN10 = 10 bar (145 psi),
  • DIN PN16 = 16 bar (230 psi)
  • DIN PN40 = 40 bar (580 psi)
