Client Background & Production Challenges

A leading industrial manufacturer in Russia specializing in oil and gas transmission infrastructure needed to upgrade its pipeline processing workshop. The facility routinely processes heavy seamless and welded steel line pipes with outside diameters ranging from Ø89 mm to Ø460 mm.

Prior to implementing CNC laser technology, the factory relied on conventional band saws, plasma cutting, and manual grinding to prepare pipe joints for welding. This traditional approach led to several critical bottlenecks:

• Inaccurate Bevel Angles: Manual grinding produced uneven root faces and angle variations, leading to fit-up errors and slower robotic orbital welding speeds.

• Excessive Tailing Scrap: Conventional saws and chuck systems left long tailing remnants, wasting valuable heavy-wall raw material.

• High Processing Costs: Relying exclusively on pure gases and multi-step manual operations resulted in excessive labor and consumable expenses.

  
  

The Solution: Longxin LX-T52 Heavy Duty Tube Laser Cutting Machine

To streamline multiple cutting, profiling, and beveling stages into a single automated setup, the client selected the LX-T52 heavy duty tube laser cutting machine. Engineered specifically for large-diameter structural pipes and pipeline fabrication, the LX-T52 features a rigid side-mounted machine bed, a 525×525 mm full-stroke pneumatic chuck, and intermediate follow-up supports.

Core Technical Features Delivering Results

1. Robust Clamping for Large Pipes (Ø89 mm – Ø460 mm)

The system's full-stroke pneumatic chuck handles single-tube weights up to 2,000 kg (≤ 166 kg/m) across lengths up to 12 meters. The pneumatic four-jaw mechanism eliminates manual clamp changeovers across the entire Ø89–460 mm range.

2. Multi-Axis 3D Bevel Cutting (±45°)

With a five-axis cutting head and non-contact capacitive tracking (0.2 mm clearance), the LX-T52 executes single-pass V, Y, X, and K-groove bevels up to ±45°. Automatic edge-finding and center calibration ensure bevel consistency even on pipes with slight surface deviation.

3. Dual-Gas Processing Optimization (Oxygen & Compressed Air)

• Oxygen (O₂) Cutting: Produces dross-free, vertical cuts on thick carbon steel pipeline walls up to 25–35 mm.

• High-Pressure Air Cutting: Delivers high processing speeds on light-to-medium wall thicknesses, reducing overall gas expenses.

4. Zero-Tailing Material Savings

The synchronized front-and-rear chuck design allows the front chuck to shift dynamically during cutting, reducing tailing drop-off length to 0 mm under compatible nesting layouts

Operational Results & ROI

Integrating the LX-T52 heavy duty tube laser cutting machine delivered quantifiable production improvements for the Russian facility:

• Direct-to-Weld Precision: Precise bevel tolerances (±0.5°) eliminated the need for secondary manual grinding before orbital welding.

• 60%+ Higher Production Throughput: Merging sawing, hole cutting, and edge milling into one CNC cycle drastically shortened production cycles.

• Over 10% Raw Material Savings: Zero-tailing capabilities and Bochu automatic nesting algorithms minimized pipe drop-end waste.

• Lower Auxiliary Operating Costs: Utilizing compressed air cutting where appropriate cut auxiliary gas expenses significantly.
