Material Specification

The GB/T 9948 standard specifies seamless steel pipes designed for use in petroleum cracking. These pipes are crafted to withstand high temperatures and pressures, making them ideal for the demanding environments of the oil and gas industry. The materials used in these pipes include various grades of alloy steel, such as 10, 20, 12CrMo, 15CrMo, and 12Cr1Mo, each offering distinct properties to suit specific applications.

Key Features

High Temperature Resistance: Designed to perform under extreme temperatures.
Corrosion Resistance: Enhanced durability against corrosive substances.
High Strength: Capable of withstanding high pressures.
Precision Manufacturing: Ensures tight tolerances and consistent quality.
Versatile Applications: Suitable for various petroleum cracking processes.

Chemical Composition

The chemical composition of these steel grades is crucial for their performance. Below is a table presenting the typical chemical composition for each grade:

Element (%)	10	20	12CrMo	15CrMo	12Cr1Mo
C	0.07-0.13	0.17-0.23	0.08-0.15	0.12-0.18	0.08-0.15
Si	0.17-0.37	0.17-0.37	0.17-0.37	0.17-0.37	0.17-0.37
Mn	0.35-0.65	0.35-0.65	0.40-0.70	0.40-0.70	0.40-0.70
Cr	-	-	0.90-1.20	0.80-1.10	0.90-1.20
Mo	-	-	0.25-0.35	0.25-0.35	0.25-0.35
P	≤0.035	≤0.035	≤0.035	≤0.035	≤0.035
S	≤0.035	≤0.035	≤0.035	≤0.035	≤0.035

Mechanical Properties

Property	10	20	12CrMo	15CrMo	12Cr1Mo
Tensile Strength (MPa)	≥335	≥410	≥450	≥440	≥470
Yield Strength (MPa)	≥205	≥245	≥295	≥295	≥295
Elongation (%)	≥24	≥20	≥20	≥20	≥20
Impact Energy (J)	≥27	≥27	≥27	≥27	≥27

Steel Grade

The steel grades covered under GB/T 9948 include:

10: Low carbon steel with good weldability.
20: Medium carbon steel with balanced strength and ductility.
12CrMo: Chromium-molybdenum alloy steel with excellent heat resistance.
15CrMo: Similar to 12CrMo but with slightly higher carbon content for increased strength.
12Cr1Mo: Enhanced chromium content for superior corrosion resistance.

Application

These seamless precision steel pipes are primarily used in:

Petroleum Cracking: Essential for refining crude oil into various products.
Chemical Processing: Suitable for high-temperature chemical reactions.
Power Generation: Used in boilers and heat exchangers.
Industrial Boilers: Withstands high pressure and temperature in steam boilers.

Possible Alternative Grades

For specific applications, alternative grades may be considered:

ASTM A335 P11/P22: Comparable chromium-molybdenum alloy steels.
DIN 17175 13CrMo44: German standard for similar applications.
JIS G3458 STPA 22: Japanese standard for high-temperature service.
