We are one of the biggest projects pipeline products supplier in China, Our products contain steel pipe/tube,fittings, flanges. With development more than 20 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.

 

Scope

ASTM A105 (also known as ASME SA 105) covers seamless forged carbon steel piping components for use in pressure systems at ambient and high-temperature service.

 

Flanges, fittings, valves and various other parts ordered to customer dimension or to industry standards such as MSS, ASME and API specification are included in the scope.

 

Forgings to this specification are limited to 10,000 lbs.

 

Welding

These components can be welded. Welding procedures must comply with ASME Boiler and Pressure Vessel Code Section IX.

 

Heat Treatment

Heat treatment is not a mandatory requirement except for flanges above Class 300, flanges of special design where the design pressure or design temperature are not known and for items over 4” NPS and above Class 300. When heat treatment is required, annealing, normalizing, normalize and temper, normalize and quench and tempering shall be the applied methods.

 

Forging

This alloy is forged at between 1,700 degrees Fahrenheit and 2,200 degrees Fahrenheit, followed by quenching and tempering.

 

Annealing

Forged parts are allowed to cool to below 1,000 degrees Fahrenheit before reheating to between 1,550 degrees Fahrenheit and 1,700 degrees Fahrenheit. Slow furnace cooling follows.
