Seaming - Import export

CNC controlled machine for belt grinding and polishing stainless steel weld seams. Belt grinding on the contact wheel or slack belt unit is possible for edge profiling.

FLEXIBLE, SAFE AND PROVEN THE WORLD OVER – THE LIPP DOUBLE SEAM SYSTEM Conventional systems are often unsuitable for the optimum, safe storage of solid or liquid substances and their use can result in premature corrosion, leaks and problems with safety. Flexibility is another important factor. Tanks must be flexible in terms of size and substrate and optimally adaptable to the local conditions. THE LIPP DOUBLE SEAM SYSTEM HAS PROVEN ITSELF TIME AND TIME AGAIN ALL OVER THE WORLD FOR MORE THAN 45 YEARS MULTI AWARDED. The principle of the LIPP Double Seam System is as follows the edges of steel strips are folded over together twice, connecting them together in such a way that even aggressive liquids inside the tank cannot find any surfaces to attack. The result corrosion is prevented and maximum leak tightness is achieved.

SYSTEM SOLUTIONS FOR MUNICIPAL WASTE WATER TREATMENT Lipp has for many decades been an established partner of municipal waste water treatment plants, engineers and general contractors in the field of tank and system solutions for municipal waste water treatment. Due to their method of construction as well as flexibility in the choice of materials and ideal diameter – height ratios, Lipp tank and system solutions are especially suitable for the needs of small to large sewage treatment plants. They are ideally tailored to one another, but may also be embedded as individual island solutions into existing systems and are therefore equally popular with planners and end users alike. The stainless steels used and the double seaming guarantee maximum water tightness and durability with low maintenance for a wide variety of waste waters, slurries, process liquids and gases. The versatility in terms of the system solutions offered for municipal waste water treatment plants

Settling and floating layers are avoided by horizontal and vertical mixing. Before plant construction, coordination takes place with the future plant operator to determine the optimum stirring technology based on the respective substrates. Operational safety is ensured by the closed reaction chamber, the external drive for the agitator and the externally mounted electric drives. Variable dimensions and substrate flexible stirring technology also allow the use of difficult substrates. The wall heating system, externally mounted on the fermenter wall, ensures optimum fermentation conditions and a high gas yield. FAST ASSEMBLY – LESS COST Low installation costs are possible by using the Lipp dual seam system and on site production. If the foundation slab is provided along with assistance during assembly, costs fall still further.

The central agitator has a low energy requirement to ensure mixing and ensures optimum biological digestion. This is helped by the smooth internal walls (largely without any internal attachments) which prevent substrate deposits. As an option, an external heating system can be added to the digester, ensuring an even temperature distribution thanks to the good heat transfer properties of the steel.

MAXIMUM LEAK TIGHTNESS AND PRACTICAL ON SITE CONSTRUCTION With Lipp digesters you will benefit from over 50 years experience in plant and tank construction.

Our 20 kHz roll seam welding heads are particularly suitable for continuous welding of thin aluminum foils or copper foils. Ultrasonic roll welding is similar to ultrasonic welding. Due to the discshaped sonotrode, however, a continuous weld can be generated without interruption. Thanks to the inductive energy coupling, the 20 kHz roll seam welding heads are maintenancefree.

For heavy-duty seams, jeans, workwear, upholstered furniture and mattresses. Rub and abraison resistent / Suitable for multi-directional sewing / Sewing with low tension levels possible / Suitable for use with automatic sewing machines.

The automatic weld chamfering machine ASO 920 is for portable use in weld seam preparation. The attachment of large welded chamfers on the workpiece upper edge up to a chamfer length of 90mm can be performed by the machine effortlessly without any thermal change to the material, because the heat dissipation occurs through the chip. V, X, K, U or Y seams can be prepared thanks to the gradual angle adjustment from 0° - 30°. The highlight here is the machining preparation of a tulip seam. The machine is very durable and shows its’ strength in every material through their sturdy construction. Extremely high tool service life can be achieved with the low-speed chamfering. Sheet thickness started at 8mm can be processed. Advantages: Easy to adjust to material thickness, chamfer angle and working height Cutter head can be set in Z and X-axis No change to material properties, through heat dissipation via chip V-, X-, K-, U- or Y- seams possible

The automatic recess chamfering machine ASO 910 is for welded seam treatment of, for example, duplex steel. The recess chamfering or resetting of cladding is mastered excellently by the edge chamfering machine. The attachment of chamfers on the top edge of the workpiece is possible up to 65mm. Thanks to the gradual angle adjustment from 90° - 75°, clean transitions are created between two workpieces with different thicknesses. The machine is very durable and shows its’ strength in every material through their sturdy construction. Extremely high tool service life can be achieved with the low-speed chamfering. Sheet thickness started at 8mm can be processed. The front, top and/or bottom side can be processed in one step through a special shape chamfer. Cavities in the front can be chamfered using the disc groove cutter. Advantages: Easy to adjust to material thickness, chamfer angle and working height Cutter head can be set in Z and X-axis No thermal change to the material

The automatic weld-chamfering machines from the ASO 930 series are for stationary and portable use in weld seam preparation. The attachment of large welded chamfers on the workpiece bottom edge up to a chamfer length of 74mm can be performed by the machine effortlessly without any thermal change to the material. V, X, K or Y seams can be prepared thanks to the gradual angle adjustment from 0° - 75°. The machines are very durable and show their strength in every material through their sturdy construction. Extremely high tool service life can be achieved with the low-speed chamfering. Sheet thickness started at 8mm can be processed. Smaller workpieces can be processed manually. Advantages: Easy to adjust to material thickness, chamfer angle and working height No thermal change to the material V-, X-, K-, I- or Y- seams possible Very long operating life and cutting performance Gradual feed adjustment depending on material from 0 - 1.

The automatic weld-chamfering machines from the ASO 900 series are for stationary and portable use in weld seam preparation. The attachment of large welded chamfers on the workpiece upper edge up to a chamfer length of 53mm can be performed by the machine effortlessly without any thermal change to the material, because the heat dissipation occurs through the chip. V, X, K or Y seams can be prepared thanks to the gradual angle adjustment from 15° - 80°. The machines are very durable and show their strength in every material through their sturdy construction. Extremely high tool service life can be achieved with the low-speed chamfering. Sheet thickness started at 8mm can be processed. Smaller workpieces can be processed manually.
