In the final analysis, the market competition is the competition for customers. Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work. The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service.

Q370R Pressure Vessel Steel: Steel used to manufacture pressure vessels in petrochemical, gas separation, gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The commonly used steels en10025 S460ML are mainly low-alloy high-strength steel and carbon steel. Q370R implements the domestic standard GB713-2008.

en10025 S460ML, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.

12Cr1MoVG high pressure boiler tube belongs to seamless steel tube. The manufacturing method of 12Cr1MoVG high pressure boiler tube is the same as that of seamless steel tube. High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and steam, oxidation and corrosion will occur. en10025 S460ML, 12Cr1MoVG high pressure boiler tube is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good microstructure stability.

The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.

It is a modern high-tech professional enterprise integrating scientific research, en10025 S460ML production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as en10025 S460ML process technology development, technology transfer and related technical consulting and technical services.
