OEM & Custom Services / OEM

We understand that standard catalogs cannot cover all project needs. Our OEM customization services allow you to tailor Alloy 718 stub ends to your exact specifications:

Special End Preparation:

Bevel ends (Standard or J-preparation) for welding, ensuring optimal weld penetration for Alloy 718

Custom Dimensions:

Non-standard stub end lengths or special radii for unique piping layouts

Custom wall thicknesses for high-pressure integrity

Marking:

Laser marking or low-stress stamping with your logo, alloy grade, heat number, and specification details. Low-stress stamping is critical for nickel alloys to prevent stress concentration points.

Custom Packaging:

Plywood cases, steel crates, or heat-shrink wrapping with custom labeling for inventory management and export protection.
