Black oxidation treatment is a commonly used chemical surface treatment method for metal parts, including steel, stainless steel, copper and brass. The principle of this process is to immerse the metal in a heated solution containing oxidized salt, so that the metal surface forms a black oxide film to achieve the purpose of rust and corrosion resistance. This oxide film is usually iron tetraoxide (Fe304), which not only improves the corrosion resistance of the metal, but also gives it a black appearance. This surface treatment is widely used in areas such as precision machining projects, automotive parts, tools and decorations, and the advantages of black oxide include better corrosion protection, reduced light reflection, dimensional stability and aesthetic appeal. In short, the black oxidation treatment is a versatile technology suitable for the improvement and protection of various metal parts.

Universal expansion joints absorb axial, lateral and angular movement simultaneously. Installation is primarily in the low pressure area. Using a guide tube protects the metal bellows from abrasive media or flow-induced oscillations. The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.

Axial expansion joints compensate assembly tolerances and thermal longitudinal expansion in the direction of the tube axis. Depending on the design, they can be impinged with pressure internally and externally. Using a guide sleeve protects the metal bellows from abrasive media or flow-induced oscillations. The reaction forces caused by the internal pressure must be absorbed by sufficiently dimensioned anchor points.

Plastic for welding … Welding is often the simplest and best way of fastening. The range of different perforated plates offers a wide range of applications. Size and quantity of the welding joints depend on the substructure and must be defined on site. Please note that the perforated metal sheet can under no circumstances take over any static functions. The secutex buffer pad is simply disconnected by grinding away the welding spots. These are the advantages Simply weld onto the item to be welded No need for repeatable holes in the workpiece No holes in the secutex impact protection material Applications On all metal surfaces On thin metal walls Everywhere where screwing is not possible or screw holes are unwanted Examples Collecting basins Ramp protection metal boxes Container Forklift Gripper Girder protection Pallet truck 1. Perforated metal sheet, overhang at the side This version is suitable for welding onto flat surfaces and extrawide profiles of construction steel.

Apply the paste evenly and thinly with a brush, spatula, etc. Remove excesses. Do not use paste instead of grease and mix only with suitable lubricants.

With the GPL 3000 Ex you can detect the smallest of leaks. Leak detection is particularly problematic for seals with swellable materials. The leak detection sprays cause the sealing materials to swell and the leak is temporarily sealed again. The use of a gas detector is essential in this area. The sensor in the GPL 3000 Ex is protected from dirt and mechanical stress by a metal protective cap. Clear display of the measured values makes it easy for inexperienced users to find leaks. Together with the robust metal sensor head and the stable casing, the GPL 3000 Ex is a professional leak detector for everyday work.

The measuring element of this load cell consists of a double bending beam with strain gauges, the resistance of which changes with the application of force. Upon applying a voltage to the strain gauge bridge, the change in the strain gauge resistance is converted into output voltage, which is directly proportional to the force. The strain gauges and the entire measuring element are protected from water spray by metal cover including sealing material. The tensile or compressive load to be measured is applied to the sensor element through the M6 threaded hole located on each end face. The load can be applied easily, along the sensor axis. This serves to prevent falsification of the measured values. Overload protection can be realized with little effort using a mechanical stop. FEATURES Measuring ranges from 0 … 20 N to 0 … 880 N Relative non-linearity: ±0.25 % F.S. Many load cycles Protection class IP54 Excellent price-performance ratio burster TEDS optionally available
