Quenching method for deformation and cracking of seamless steel pipes

Update time : 2023-04-20 09:06:43

　　Seamless steel pipes may experience deformation and cracking during the quenching process, mainly due to improper heat treatment processes during the quenching process. The following are some quenching methods that may cause deformation and cracking of seamless steel pipes:

　　Direct fire: Direct fire is a heat treatment method that directly heats seamless steel pipes to high temperatures and quickly cools them. If the temperature and time of direct fire are not properly controlled, it may lead to deformation and cracking of seamless steel pipes.

　　High frequency quenching: High frequency quenching is a heat treatment method that uses high-frequency current to heat the surface of seamless steel pipes and quickly cool them. If the high-frequency quenching process is not appropriate, it may cause the surface of seamless steel pipes to overheat, leading to deformation and cracking.

　　High temperature quenching: High temperature quenching is a heat treatment method that rapidly cools seamless steel pipes after heating them to high temperature. If the temperature and time of high-temperature quenching are not properly controlled, it may lead to deformation and cracking of seamless steel pipes.

ASME B31.3 Steel Pipe Pressure and Wall Thickness Calculation

Oct .29.2026

　　The ASME B31.3 wall thickness of a steel pipe is directly related to its pressure-bearing capacity. Generally, the greater the wall thickness, the greater the pressure the pipe can withstand. this relationship is not a simple direct proportion; it requires precise calculation using standard formulas.Shengtian Group will introduce the most commonly used wall thickness calculation formulas in the American and Chinese standard systems, as well as the key parameters to consider during the calculation process.

ASME/ANSI B36.10 & B36.19 Steel Pipe Dimension 3 Characters:A completely description for steel pipe dimension includes outer diameter (OD), wall thickness (WT), pipe length (Normally 20 ft 6 meter, or 40 ft 12 meters).

EN 10219 S460MH Steel Pipe: Selection & Application

Oct .22.2026

EN 10219-1 is the European standard for cold-formed welded structural hollow sections. S460 is the high-strength grade within this standard. The “S” stands for structural steel, “460” means a minimum yield strength of 460 MPa, “M” means thermomechanical rolling, and “H” means hollow section.Shengtian Group this guide covers S460MH under EN 10219-1, as well as S460NH and S460NLH under EN 10210. You will find material data, size ranges, selection logic, driving suitability, and certification requirements.

How to Choose Carbon Steel Pipe Size?

Oct .20.2026

When selecting carbon steel pipe (CS Pipe) size, pipe diameter (NPS/DN), wall thickness (Schedule Number), and pressure rating are three interrelated core parameters. Their selection requires comprehensive calculation based on the system design pressure, flow rate, and medium characteristics.
