Hose Type: Type PTFE – ELAFLON PTFE (with helix)
Product NameType PTFE
Part NumberPTFE SD
Short DescriptionELAFLON PTFE (with helix)
DescriptionUniversal hose ELAFLON PTFE with electrically conductive, seamless lining of PTFE (Polytetrafluorethylene). Suitable for all commonly used chemicals, see resistance chart.
Suitable for both suction and delivery (Type PTFE D = delivery). Working pressure up to 16 bar, burst pressure >64 bar.
Temperature range from -30° up to +150° Celsius (depending on medium). Chemical resistance see resistance chart. Steaming out for cleaning and sterilisation permissible up to +150° C, max. 30 min.
Meets EN 12115. FDA und USP Class VI conform according EC regulations 1935/2004 and 10/2011.
Application

As suction and discharge hose for barrels, containers, rail tank cars, tankers and fixed installations.
The steel helix ensures that the hose keeps in shape during suction and gravity operations, even with tight bending radii.

CommentThe PTFE lining is electrically conductive, seamlessly extruded, and smooth – therefore low pressure drop in service and easy cleaning properties. No cross contamination or discoloration of media thus being excellent when very pure media are being carried. Lining conform to FDA / USP Class VI.Electrical conductivity:
Ω/T-type to EN 12115. Electrical resistance of <106 OHM between hose ends, <109 OHM from lining to cover, through the hose wall. Suitable for use in EX-Zones 0, 1 and 2.
Easy assembling: Ω/T-hoses have the added advantage that metallic conductive elements do not have to be connected to the hose fittings.
LiningPTFE, electrically conductive, black, seamless, smooth bore
ReinforcementsHigh-tensile, temperature resistant, textile braids, additionally with galvanised steel helix
CoverEPDM, electrically conductive, black, abrasion and flame resistant, resistant against weather and ageing
CertificatesManufacturer's declaration - absence of silicone.
MarkingBlue-white-red coloured spiral and abrasion resistant continuous embossing

Example Pictures Hose Unit (Coupler):
Example Pictures Tank Unit (Adapter):
DescriptionHose unit with swivel, typically mounted on hose assemblies and loading arms for temporary connection to storage tanks and mobile transport units, for loading and unloading.
Tank unit without swivel, typically fix mounted as filling connector on storage tanks, mobile tanks like IBC and ISO containers, road tankers, rail tank containers and ship manifolds.
CommentQuick and safe connection of hose assemblies and loading arms to mobile and stationary tanks, under pressure and with minimised liquid loss.
The standardised interface to STANAG 3756 with its bayonet coupling principle has been widely accepted in the industry. Both coupling parts are equipped with a flat poppet valve.
For the connection, the hose unit is pushed onto the tank unit and coupled / sealed by turning the coupler clockwise by 15 degrees. When the unit is turned by 100 degrees, the valves move into the tank unit so that the medium can flow. When a similar turn is made counter-clockwise, the flow is stopped and the coupler can be pulled off.
PressureCan be coupled up to 7 bar line pressure.
Working pressure:
Aluminium ≤ DN 50 = PN 16,
Aluminium ≥ DN 65 = PN 10 (PN 16 on request),
Brass/Gunmetal = PN 16,
Stainless steel, Hastelloy, Titan = PN 25,
PEEK, PVDF = PN 6.
-20° C up to +80° C;
fulfilment of larger temperature range -50° C up to +200° C is possible - depending on medium, coupling and sealing material.
MaterialBody: stainless steel (1.4401/1.4404, AISI 316 /316L, 1.4408/1.4409, CF-8M/CF-3M), aluminium or brass (up to 2") / bronze (from 2½") – others on request.
O-Rings: Viton® (FPM/FKM) – others on request.
Flat seal (for female parallel thread connections only): PTFE (stainless steel couplings), PU (alu / brass (bronze) couplings) – others on request.
CertificatesDDC couplings fulfill the requirements of European Pressure Equipment Directive category 2 (for higher demand on request).
They are suitable for the use in potentially explosive atmosphere (ATEX) zone 1, approved for the transport of dangerous goods on road (ADR), by rail (RID) and by ship (IMDG), specified as a branch standard from European Chemical Industry (CEFIC) for handling of Ethylene Oxide/Propylene Oxide, Acrylic Monomers, Acrylonitrile, polymeric MDI/TDI and Vinyl Chloride.
