Welcome to Hofland Deltaflex Rubbertechniek BV. Hofland Deltaflex Rubbertechniek is a producer and supplier of a large scale of technical rubber products. Hofland Deltaflex Rubbertechniek is a well known supplierof technical rubber products, metallic gaskets, jointing material, stuffing box gaskets, composite hoses andengineering plastics as well as soft PVC strip curtains and doors for the petrochemical industry, martime sectorand industry at large.Until 1993, Hofland Deltaflex Rubbertechniek was known under the name Heeneman Rubbertechniek. The company has a long history at the Zuiderweg in Hoogkerk, near Groningen. In 1993 the company merged into the Hofland Deltaflex Group. This company was purchased by the Royal Econosto Group 1997. In 2001Hofland Deltaflex Rubbertechniek moved to a modern production facility in the town of Leek (appr. 9 miles

from Groningen. Due to an MBO, in 2006, Hofland Deltaflex Rubbertechniek left the Econosto Group andbecame an independent company again.

Nowadays, an enthousiastic team of specialists (from former companies as Deltaflex, Hofland and Heeneman) offers you many solutions in rubber, gaskets and hoses. Hofland Deltaflex Rubbertechniek is supplier and producer of an enormous range of rubber products, gaskets in non-metallic as well as metallic. .

We are also supplier of standard trading products as rubber sheets, profiles, ringmats, soft and metallic gaskets, hoses, and soft pvc products. We produce also a lot of custom-made products. Hofland Deltaflex Rubbertechniek is specialised in small series as well as large series, and also in rubber-metal bonded parts.

Hofland Deltaflex Rubbertechniek B.V. can supply a wide range of high quality sealing products designed for flange applications in the industrial and manufactoring sectors.

Spiral Wound Gaskets

DescriptionSpiral wound gaskets consist of a V-shaped metal strip spirally wound, in combination with a soft, filler material. The metal strip provides outstanding recovery , while the flexible filler guarantees excellent sealing. Due to this combination of materials the spiral wound gasket is suitable for sealing under severely fluctuating temperature and pressure conditions.Depending on the application the spiral wound gasket can be specified with or without inner ring and outer ring.

Properties Spiral wound gaskets are suitable for use across a wide gasket stress range.Spiral wound gaskets can be used to seal fluid pressures up to 250 bar and from cryogenicelevated temperatures up to 1000 degrees. Because of the robust design of the spiral wound gasket it is simple to install without damagealthough care should be taken in transporting and installing large diameter gaskets without inner or outer guide rings.The outer ring simplifies assembly and prevents blow out of the gasket By combining different winding materials and metals the gasket can be tailored to suit a wide variety of operating conditions. The gasket is non-adhesive and easily removed and will not damage flange surfaces.

Seating stress Spiral wound gaskets should preferably be mounted within the following gasket stress range to ensure a leak-proof connection.

Flange SurfaceThe recommended surface roughness of the flange faces, between which a spiral wound gasket

is mounted, is 3.2 - 6.3 umRa (125-250 RMS), also referred to as smooth finish.

Benfits of the centring ring:

The spiral wound gasket outer centring ring provides the following benefits:1. Optimum location between the bolts.2. Protection of the spiral wound element.3. Additional security against gasket blow-out.4. Acts as compression limiter preventing overloading and overcompression of the spiral wound element.5. Prevents radial-flow of soft fillers, such as P.T.F.E.For these reasons it is preferable to use a spiral wound gasket with outer centring rings.On the outer ring the gasket is marked with nominal size, pressure class, standard and materials.

Benefits of the inner ring: The spiral gasket inner ring provides the following benefits:1. Prevents radial-flow of soft fillers, such as P.T.F.E.2. Reduces turbulence-minimising flow resistance and crevice corrosion.3. Acts as a heat shield when the spiral wound gasket is subjected to high temperatures.

Inner and outer rings are particularly recommended for use on spiral wound gaskets exceeding class 600lbs, but specifically recommended for high temperatures and pressures to optimise the operational reliability of the spiral wound sealing element.

Material Selection Material selected for the inner ring and winding metal is usually the same as the material of theflanges in order to prevent corrosion and differential expansion problems. The outer centring ring is generally manufactured from carbon steel with an anti- corrosion treatment, however the ring may also be manufactured in the same metal as the flange to prevent corrosion problems.

Standard Materials for spiral wound windings

The table below may be used for determining the correct filler. It should be pointed out that graphite is the optimum filler in many cases. Only when graphite can cause pollution of the medium, or is not chemically resistant, is it advisable to apply another type of filler material.

GRAPHITE is universally applicable, high-quality, asbestos-free material with the following characteristics: very good chemical resistance, resistance to ageing, good gastightness.

PTFE is a high quality synthetic material with the following characteristics: excellent chemical resistance, resistance to 250oC, resistant to ageing, excellent gastightness.

Non standard materials are available on request.

How to order spiral wound gaskets :

A correct purchase order should contain following information :

Example :

1. Type of Spiralwound gasket : SG-IR 2. Standard of the gasket : ASME B16.20 (flange ASME B16.5)

3. Nominal size and pressure class : 1" - 150 lbs 4. Material - inner ring (if applicable) : SS 316L - metal winding : SS 316L - filler : Graphite - outer ring : Carbon steel

If it is required to supply with Material certificates, you should mention this in your RFQ (request for quotation) 3.1B can be sent with the shipment of the gaskets..
