Different type of ASTM pipes and their speciation
ASTM A106 GRADE B is commonly used in construction gas and oil factories. It is also used in Boilers, power plants, petrochemical industries and also in ships when a large quantity of liquid is to be transported.
Scope:
It covers a seamless carbon steel nominal wall pipe for the services where high-temperature is involved in.
The process uses,
The melting process used is,
- Open hearth, basic oxygen or electric furnace combined separately with degassing.
The Steel cast used is permissible.
The final hot-finished pipe is not necessarily needed to be heat-treated, but the cold-drawn pipe must be after the cold draw is passed through them.
API 5I GRADE B:
This particular spread is consistent and welded with a steel line pipe. It is a steel pipe for pipeline transportation frameworks in the oil and flammable gas businesses.
Grades secured by this determination are
- A25
- A
- B
- X42
- X46
- X52
- X56
- X60
- X65
- X70
- X80.
ASTM A53 GRADE B:
It is also called as the ASME SA53 pipe.
ASTM A53 pipe is proposed for mechanical and pressure applications and is additionally adequate for customary utilizations in steam, water, gas and carriers. It is appropriate for welding and for framing tasks including looping, bowing, and flanging, subject to specific capabilities.
ASTM A333 GRADE 6:
ASTM A333 Grade 6 combination pipe will be made by the consistent or welding measure with the expansion of no filler metal in the welding activity.
IS 1239 PIPE:
It has some very important features like,
- High strength
- Resistance for corrosion
- A high percentage of toughness
- Higher deformity
Applications:
ASTM A335 P5 PIPE:
The P5 pipe is a consistent ferritic combination steel pipe utilized for high-temperature applications. These channels are flexible and can be utilized to send water, oil and flammable gas. Key to the creation of this chrome-moly composite P5 is the expansion of chromium and molybdenum.
ASTM A335 P9 PIPE:
The P9 pipe is a consistent ferritic composite steel pipe utilized for high-temperature applications. These funnels are adaptable and can be utilized to send water, oil and gaseous petrol. Key to the arrangement of this chrome-moly amalgam P9 is the expansion of chromium and molybdenum.
ASTM A335 P11 PIPE:
Chromium, or chrome, improves high-temperature quality, expands oxidation obstruction and raises the tractable, yield and hardness at room temperatures. … It builds the protection from relaxing, limits grain development and makes chromium steel less defenceless to embrittlement.
ASTM A335 P22 PIPE:
The Grade P22 Alloy Steel Seamless Pipes are Carbon steel pipes with an expansion of chromium, molybdenum, and once in a while vanadium. Chromium, or chrome, improves high-temperature quality, builds oxidation opposition and raises the tractable, yield and hardness at room temperatures
The P91 pipe is ferritic composite steel that has high-quality properties, which don’t break down with time and are creep safely. It is additionally called 9 Cr 1 Mo steel, or chrome moly pipe, because of its creation
