welding of nm400 steel sheet for highway bridges
Since it was established in 2000. Based on the domestic rich welding of NM400 steel sheet product resources and the great steel demand of the international market, our welding of NM400 steel sheet service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
After years of operation and accumulation, the company has formed an operation network covering major economic cities across the country, with a group of high-quality professional logistics technicians and management personnel, strong strength and stable logistics channels. The company's business operations include the loading and unloading of steel raw materials and finished materials, welding of NM400 steel sheet warehousing, and freight transportation. Our logistics service business has passenger transportation, automobile and construction machinery inspection, logistics information management and operations.
During the construction of hot-dip welding of NM400 steel sheet galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the welding of NM400 steel sheet construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
Our client purchase more than 900 tons pipe welding of NM400 steel sheet from India. And we do the inspection for each one pipe before shipment.During the inspection, the inspector saw that the surface of the square pipe kept the original color of the stainless steel, no fracture, no depression and other quality defects was found.
The yield strength of welding of NM400 steel sheet, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.
