Overview

4130 carbon steel pipe from Tsingshan Steel (Shandong) is specified for export buyers who need Cr-Mo alloy pipe for mechanical, oilfield-related, and high-strength fabrication packages under AISI 4130 practice. Purchase reviews typically lock grade 4130, outside diameter, wall thickness, length, end finish, heat treatment condition, and NDT scope when required. Before offer release we align packing, destination port, and documents. MTC EN 10204 3.1, heat marks, and optional SGS/BV/Intertek inspection can be coordinated before loading. Send OD x wall, length, ends, heat treatment, quantity, end use, and destination port for a practical export quotation.

Applications

Mechanical and high-strength fabrication packages
Oilfield-related and equipment piping where 4130 is specified
Export alloy pipe lots with heat-treatment confirmation
Projects needing Cr-Mo chemistry beyond mild carbon pipe

FAQ

What should I confirm before ordering 4130 carbon steel pipe?

Confirm grade 4130, OD, wall thickness, length, ends, heat treatment condition, quantity, destination port, packing method, NDT needs, and whether EN 10204 3.1 MTC or third-party inspection is required.

How does 4130 differ from mild carbon ERW or seamless pipe?

4130 is a Cr-Mo alloy grade chosen for higher strength and specific mechanical applications, not general mild structural service. Mild carbon ERW/seamless grades are more common for general construction and low-pressure lines. Share design requirements for a practical recommendation.

What export documents can ship with 4130 pipe?

We can coordinate mill test certificates (typically EN 10204 3.1), packing lists, commercial invoice support, heat identification, loading photos, and optional SGS, BV, or Intertek inspection before shipment.
