1. Thermomechanical treatment. High-temperature thermomechanical treatment can increase the yield ratio and elastic limit of spiral steel pipes. Improve the comprehensive mechanical properties, fatigue properties, and stress relaxation properties of spiral steel pipes. Reducing the ductile-brittle t
1. LSAW steel pipes should be submitted for acceptance in batches, and the batching rules should meet the requirements of the corresponding product standards.2. The inspection items, sampling quantity, sampling location, and test method of LSAW steel pipes shall be following the provisions of the co
Surface treatment method of anticorrosive spiral steel pipe1. The surface of the anticorrosive spiral tube is cleaned with solvents and emulsions. Remove the organic matter on the surface of the spiral tube, but it cannot remove the surface rust, oxide scale, welding flux, etc.2. Use a wire brush, s
The guaranteed method of the wall thickness accuracy of the straight seam steel pipe1. Tube billet heatingThe heating should be even, and the rapid rise and fall of the temperature should be avoided. The temperature of each rise and fall should be steady and slow, and the temperature of the rise and
Product: Seamless steel pipe. Standard: ASTM A106. Material: Carbon steel. Thanks for the confidence from the customer in Australia. Cooperating with threeway for more than 8 years. Australia pipe customers perfect receipt
Thick-walled steel pipes, the steel pipe whose outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. Mainly used as petroleum geological drilling pipes, cracking pipes for the petrochemical industry, boiler pipes, bearing pipes, and high-precision structural pipes
Annealing steps for straight seam steel pipesAnnealing of straight seam steel pipes is to heat the steel pipe to a temperature and keep it at this temperature and then slowly cool it to room temperature. Annealing includes annealing, spheroidizing annealing, and stress relief annealing.1. Heating th
How to purchase straight seam steel pipesFirst of all, you need to understand the types of steel pipes1. Divided by type: straight seam steel pipe, seamless steel pipe, spiral steel pipe, etc. 2. Classification of cross-section shape of straight seam steel pipe: square pipe, rectangular pipe, oval t
