Product Introduction
The steel slip on flange from HAIHAO is a forged pipe connection component designed for easy alignment and assembly in piping systems. Manufactured in China under strict adherence to ASME B16.5 standards, this steel slip on flange slides over the pipe end, allowing for fillet welding which reduces the need for precise cutting.

Product Advantages
1.Lower pipeline life-cycle cost: Forged raw materials combined with rust preventive oil or hot-dip galvanizing surface treatment effectively extend the product service cycle.
2.Cost control in engineering project implementation: With a monthly supply capacity of 2000 tons, the product can realize phased and batch supply according to the construction schedule of large-scale industrial projects, avoid the construction delay cost caused by the shortage of connection components, and the batch procurement mode can realize the scale effect of procurement and reduce the unit procurement cost of flange products.
Applications
Petroleum, chemical and natural gas
For pipeline connection of reactors, storage tanks and compressors, adapting to medium corrosion and high-pressure working conditions.
Electric power
Matches pipeline connection of boilers, steam turbines and heat exchangers, withstanding high-temperature and high-pressure pipeline environments.
Shipbuilding, marine and municipal engineering
Applied to ship ballast, urban water supply and gas pipelines, adapting to seawater corrosion and outdoor complex environments.
