Temperature range
- Low temperatures up to - 196°C;
- High temperatures up to +625°C;
Operation
The control lever, reducer, drive (electric, pneumatic, hydraulic, pneumatic hydraulic drive)
Features
- Various types of structures which are used in the oil and gas industry;
- Competitiveness in terms of cost and delivery;
- Constructions for installation on vertical pipes with a horizontal rod are provided (for example, vertical processes of platforms);
- Manual or by means of a drive.
Operation depending on the type of construction:
- Operation in places not requiring maintenance, for example, pumping gas pipelines, underground / remote installations, underwater pipelines;
- Heavy duty operation (easy removal of the crane body from the pipeline for inspection, maintenance and repair on site), allows the use of forged parts from various materials: carbon steel, stainless steel and special materials;
- Operation under critical conditions that require in-place replacement and a short repair time, or in confined spaces, for example on platforms.
