Tools for installation works (1977)

Panorama of an oil refinery.

Installation of equipment at a plant construction site.

A welder welds metal structures at the plant.

Various low-mechanization devices are demonstrated.

An abrasive wheel for cleaning metal.

A cartoon explaining the disadvantages of using such wheels.

Demonstrated are abrasive wheels that allow not only cleaning, but also cutting metal of any brand and profile, chamfering for welding and selecting the root of a weld.

A cartoon explaining the versatility of this abrasive material.

Requirements for installing a wheel.

Safety requirements when working with an abrasive wheel.

Demonstrated is a high-speed electric grinder.

Cleaning a weld with an angle grinder with a wheel diameter of up to 50 mm.

Cleaning a metal surface - the reinforced wheel is installed at an angle of 15-40 degrees.

Cutting metal with an abrasive wheel.

Panorama of the plant where the equipment is being installed.

Designers and researchers of VNIIMONTAZHSPETSSTROI discuss new developments of devices for installation work.

Drawing of a basing device for cutting profile metal and small-diameter pipes.

Device manufactured according to drawings.

Cutting at an angle.

Device for cutting larger-diameter pipes.

Use of such devices directly at installation sites.

A metal frame is used, on which various mechanisms are suspended.

A bracket with a balance beam is attached directly to the structure being processed.

A pipe cutting device based on reinforced circles is demonstrated.

The device is used to cut pipes of virtually unlimited diameter.

The device is based on a roller trolley and is attached to the pipe with a chain.

Cutting is performed by rolling.

To prevent the pipe cutter from shifting along the pipe in the axial direction in the same plane as the circle, spring-loaded rollers are installed on both sides.

The pipe cutter rotates around the pipe manually.

The circle is deepened into the metal under the action of the spring.

The pipe cutter can be used to cut pipes fixed in a structure.

To form a chamfer on large-diameter pipes and to cut sheet metal, edge cutters are used.

The working element of this tool - a mortising cutter - is demonstrated.

Preparing the edge cutter for making a chamfer at a certain angle.

The tool is fed along the processed edge manually.

Processing sheet metal with an edge cutter.

Pipe cutter for pipes with a diameter of 32 to 108 mm.

It is equipped with a washer with two cutters, a cutting and a shaped one.

Gradually going deeper into the pipe, the cutters cut it and at the same time form a chamfer.

Welding work.

Slag removal from seams.

Slag removal with a bunch hammer.

Gas cutting.

Pneumatic chisel for removing burrs from a seam.

Assembling threaded connections.

Nuts on metal structures.

Assembling threaded connections manually.

Using ratchet wrenches.

Demonstration of an electric impact wrench.

Cartoon explaining the operation of an impact wrench.

Powerful impact wrenches are heavy and inconvenient when working at height and on an assembly site.
