Machined Metal Parts Pipe Guide

The Pipe Guide is a critical, heavy-duty Machine Component engineered for heavy industrial tube-forming and bending equipment and continuous metallurgical production lines. As vital spare parts for machinery brands, these custom CNC-machined metal parts provide precise axial direction, internal radius support, and bending guidance to prevent ovalization, cracking, or surface buckling during pipe manufacturing.

 

 

Key Technical & Drawing Specifications

 

Dimensional Accuracy & Fits: Features a primary outer diameter machined to Φ42 h9 (+0.062) for a high-precision sliding fit within guide channels.

 

Precision Curvature: Specially engineered with an arc radius of R1801.037 and an arc length of 702.6 mm, flanked by straight sections measuring 83 mm and 156 mm.

 

Critical Tolerances & Features:

 

Φ46 Zone Tolerance: Strict ±0.1 mm tolerance within designated contact zones.

 

Grooves & Pin Holes: Precision-machined locking grooves (Φ30, 20 mm width) and pin holes (Φ10 mm) for secure assembly.

 

Radius Transitions: Smooth internal chamfers and corner radii (R0.1 / R0.3 / 1 x 45°) to eliminate stress concentration.

 

 

Material: Cr12MoV Alloy Tool Steel

Manufactured from premium Cr12MoV alloy tool steel with a specified hardness of HRC55-58:

 

Exceptional Wear Resistance: Cr12MoV is a high-carbon, high-chromium ledeburitic tool steel known for its exceptional abrasion resistance and dimensional stability under heavy friction.

 

High Hardness & Strength: Heat-treated to HRC55-58, providing superior surface hardness to withstand intense mechanical sliding wear against metal tubes.

 

Extended Service Life: Ideal for high-stress industrial spare parts operating in rigorous, repetitive forming cycles.

 

Manufacturing Process & Quality Control

Pre-Bending Machining: According to customer requirements, raw materials undergo initial rough machining, turning, grooving, and hole drilling prior to hardening and forming.

 

Heat Treatment & Hardening: Precisely quenched and tempered to achieve the required hardness range of HRC55-58 for optimal toughness and wear resistance.

 

Precision Bending & Inspection:

 

Template Verification: Every bent curve is strictly verified against the customer drawing file testing template/gauge to ensure perfect matching with the required radius (R1801.037).

 

Traceability Stamping: Laser-marked or stamped according to specifications, accompanied by strict dimensional, material composition, and hardness reports.

 

Industry Applications & Advantages

Primary Applications:

Metallurgy production lines, tube processing units, cold/hot pipe bending mills, and steel plant equipment.

 

Key Advantages:

 

Superior Wear-Resistant Life: The Cr12MoV tool steel construction drastically reduces groove wear during high-volume pipe feeding and bending.

 

High Interchangeability: Fully compliant with original OEM specifications for quick replacement and minimal equipment downtime.

 

Custom OEM Capability: As a specialist supplier of Custom CNC Machined Metal Parts, we deliver tailored solution suites backed by full dimensional, material, and hardness inspection reports.
