Haihao Group Delivers A860 WPHY52 High-Strength Steel Tees to Indonesia
Haihao Group recently completed the production and shipment of a batch of A860 WPHY52 high-strength steel tees for a pipeline project in Indonesia. The order includes both reducing tees and equal tees, manufactured according to MSS SP-75 standards for high-pressure pipeline systems.
These A860 WPHY52 high-strength steel tees are designed for demanding service environments where strength, reliability, and low-temperature toughness are essential. The fittings were produced with strict dimensional control and underwent heat treatment and ultrasonic testing (UT) to ensure internal integrity and mechanical performance.
In addition, the material passed low-temperature impact testing at −46°C, achieving 41J / 33J, confirming the suitability of these A860 WPHY52 high-strength steel tees for cold-service pipeline applications.
