Purging Equipments

Product Details:

When welding special materials, e.g. titanium, outside of a welding chamber, there is a choice of two standard Schnorrer WS Gas drags, the WS Gas drag SS, and WS Alu Gas drag. Common to both WS Gas drags is the effective gas diffuser that prevents swirls and turbulence in the welding zone. One WS Gas drag is made of stainless steel with a sintered metal gas diffuser, and the advantage of this WS Gas drag SS is that most sizes take more than one dimension. The other standard
model, the WS Alu Gas drag is made of aluminium, and here the packing is very simple to change and economical to use. The Standard WS Gas drags are available from stock for pipes in all dimensions and for sheet materials.

The Schnorrer SC Profi  range of purge tools is for use in tubes and pipes of internal diameters from 13 mm to 215 mm. The SC Profi  is supplied as a complete unit, so there are no loose pieces to “disappear” or be lost. The SC Profi  gas cylinder consists only of two triple-sealing lip elements, a gas inlet and a gas outlet, a connecting axis and a connection hose with a rectus nipple.
There are three different kinds of connecting axis; a solid connection is used for straight pipes, a fl exible connection for elbows, and a spring connection for when the tool needs to go through several elbows, one after the other. As standard, the SC Profi  models 17-45 mm are supplied with a spring connection for use in the relatively sharp elbows met in these pipe sizes, while all other SC Profi  models are delivered with a fl exible connection.

This assembly is designed for welding vessels fi tted with an inspection chamber and in the stated range of sizes. The vessel must be placed on turning rolls, and the legs on the column are adjustable so that the tool can be used for more than one size of vessel. The gas drag is held between the 11 o’clock and 1 o’clock positions by a balance weight when the vessel turns. The setting-up time is about 5-10 minutes, and the tool can be dismantled and removed through inspection chambers of 350 mm ϕ or more. The vessel must be circular ± 30 mm and suitable for TIGwelding. There is a special Schnorrer water-cooled gas-drag for plasma welding.

• For nozzle pipes on tubes and vessels
• Sintered metal diffuser
• Heat-resistant silicon 280°C

SC Profi  Flange-Cone is designed for the welding of fl anges, couplings and short pipe lengths.
The tool consists of three parts: an aluminium cone, a gas connection pipe and the well known and proven SC Profi  disc with an integrated sintered stainless steel gas diffuser and in a special design. The construction of the gas diffuser guarantees a laminar fl ow of gas without turbulence during purging and the welding process. Gas fl ow* rates in litres/minute during purging are 10% of the internal diameter (mm) of the pipe, and typical purging times* are less than 1,5 minutes A further advantage of the Flange-Cone is that it can be used as an alignment tool to hold the pipe sections together and centre them at the same time. SC Profi  disc in the special design is available in the same dimensions as the SC Profi  discs. For larger dimensions please ask.

The WS Oxy I is a hand-held, batteryoperated oxygen analyzer. The measuring range varies from 1000 ppm to 10 ppm. The device has a maintenance-free zirconium cell with extended operating life. It is supplemented with an innovative display that represents operating state in color. This ”traf¿¿¿ c light system” provides the operator with a high level of comfort:  since the operation state can be shown in colors visually, there is no need to read the exact values. The software and the operation method of the device are identical to the WS Oxy II. Furthermore, it has a loud integrated buzzer.

Gas purge equipment for use when welding special metals and alloys, in particular stainless steel, titanium, Duplex, and super duplex. when welding this special material it is essential that the welding process takes place in an inert atmosphere in order to prevent oxidation, and this inert atmosphere is often best achieved in a welding chamber. Depending on the material or exotic alloy to be welded, the residual oxygen in the welding chamber may need to be reduced to less than 50 PPM to obtain a corrosion resistance result. Oxidation develops through contact with oxygen when the material is heated to welding temperature. After welding has ended it is important to maintain the inert atmosphere until the temperature of the work-piece is below 250 degrees C, depending on the material.

Our advanced gas purge systems are under continuous development to meet many demanding technical specifications and functional needs and to meet these needs economically.
