Confidential Company

Based on the provided process instructions, the procedure for cutting pipes and blanks includes the following steps:

1. Preparation for work

· Make sure that the equipment (cutting machine, tool, cooling systems, protection) is in good working order.

· Check the availability and compliance of personal protective equipment (PPE).

· Check the label on the pipe package: check the steel grade, dimensions, length, and the presence of a pipe passport (if required).

2. Control of incoming pipes

· Make sure that the pipes have been straightened and comply with regulatory requirements.

· Check the curvature of the pipes (deviation from straightness should not exceed permissible values).

· Measure the outer diameter of 2–3 pipes from the package using a micrometer type MK in three sections (at the ends and in the middle).

3. Setting up the equipment

· Select and install cutting tools (cutters, abrasive wheels, deburring brushes) in accordance with the steel grade and pipe size.

· Set up the stop for cutting to length:

o Pre-setting: manual or mechanized movement of the stop.

o Fine adjustment: after control cutting and measuring the length with a tape measure.

4. Cutting pipes

· Cutting should be carried out using one of the following types of equipment:

o Abrasive cutting machines " Radiak ", ALAOS.

o Cutting machines: 9A151, 9D151, 9D152, 91A11, etc.

o Spindleless machines ALBTS.

· For pipes made of steel according to TU 14-3-460, TU 14-3R-55 and export grades, use cutters with carbide plates.

· Cutting should be carried out without cooling emulsion (except for stainless steels).

· Control the length of the trim :

o At Radiak - up to 80 mm (in workshop No. 14 - up to 140 mm).

o At ALAOS - up to 80 mm (in workshop No. 14 - up to 100 mm).

o On cutting machines - up to 50 mm (in workshop No. 9 - up to 120 mm).

o On ALBTS - up to 70 mm.

5. Removing burrs

· Use:

o A folding lever with a cutter or a burr.

o Double-cutter chamfering machine .

o Brushes for ALAOS.

· Visually check each pipe for burrs.

6. Quality control after cutting

· Check:

o The length of the measuring pipes is measured with a tape measure.

o No ovalization or crumpling of the ends.

o No scratches, marks or dents.

o Perpendicularity of the cut.

· Measure the outer diameter at the points where the chuck clamps (selectively, 2–3 pipes from the package).

7. Resolving inconsistencies

· If defects are found :

o Replace the tool.

o Adjust the clamping device, steady rests, roller tables.

o Check and adjust the stop.

o Replace the brush or deburring tool.

8. Documentation

· Write in the log:

o Date, shift.

o Pipe sizes, package number.

o Number of acceptable and rejected pipes.

o Comments on quality.

9. Delivery of products

· Transfer the pipes to the UKK for control.

· Make sure that all pipes in the package are marked and comply with ND.

· Attach a label to the package (according to the identification instructions).

Safety requirements:

· Use PPE: special clothing, protective glasses, gloves.

· Do not allow work on faulty equipment.

· Observe the operating rules of the machines.

· Immediately report any discrepancies or accidents to the master
