Haihao Group Delivers ASTM A193 B7 Galvanized U Bolts with Complete Inspection Documentation for an Indian Pipeline Project

Haihao Group has recently completed the production and shipment of a batch of ASTM A193 B7 U bolts and galvanized steel support accessories for an industrial pipeline project in India. The order included multiple pipe sizes ranging from 3″ to 12″, along with galvanized flat U straps manufactured to customer specifications.

Unlike standard fastening orders, this project required comprehensive quality verification, including CNAS laboratory testing, third-party witness inspection, heat treatment records, and non-destructive examination (NDT). Every component was manufactured and inspected to ensure dependable performance in demanding industrial environments.

Shipment Details

ASTM A193 B7 U Bolts Manufactured for Heavy-Duty Pipe Support

The primary products in this shipment were ASTM A193 B7 U bolts, designed to provide reliable pipe restraint and structural support in industrial piping systems.

Manufactured from quenched and tempered alloy steel, ASTM A193 B7 U bolts offer excellent tensile strength, fatigue resistance, and long-term mechanical stability. To improve corrosion protection during outdoor service, every U bolt received a galvanized finish.

Following the customer’s request, the supplied assemblies included:

• ASTM A193 Grade B7 threaded U bolts
• ASTM A194 Grade 2H heavy hex nuts
• Two matching washers per assembly
• No PVC coating
• No rubber padding

This configuration is widely used in refineries, power plants, petrochemical facilities, and pipeline support systems where high-strength fastening is essential.

Comprehensive Quality Verification with Third-Party Witness

For this project, product traceability and inspection documentation were just as important as dimensional accuracy.

Haihao Group arranged complete testing through a CNAS-accredited laboratory, while key inspections were witnessed by an independent third-party representative.

These inspection records provide full material traceability and demonstrate that each ASTM A193 B7 U bolt complies with the specified project requirements before shipment.

Reliable Packaging and Export Preparation

After final inspection, every galvanized U bolt assembly was carefully packed to prevent thread damage and surface abrasion during international transportation.

The galvanized coating remained intact throughout packaging and loading, helping preserve corrosion resistance during sea freight from China to India.
