1250mm hot rolled steel q355gnh steel h beam plate

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, q355gnh steel h beam seamless steel pipes for ships and petroleum cracking q355gnh steel h beam steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many q355gnh steel h beam products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Our 12Cr2Mo1VR steel plate breaks through the specification limit, with a thickness of q355gnh steel h beam up to 180 mm and a single weight of 43.7 tons. The flaw detection can meet the highest level of NB / T47013 flaw detection level. Its thickness and unit weight exceed the production limit of vanadium steel. The 12Cr2Mo1VR steel plate with such specifications has high technical requirements, severe performance requirements, and great production difficulties. In the q355gnh steel h beam production process, it is easy to appear the tail area defects, which will cause the steel plate to fail inspection. So please choose your suppliers carefully.

With the development of API5L-B pipeline steel plate technology and the advancement of welded pipe forming and welding technology, the application scope of pipeline welded pipe is gradually expanding, especially the advantages of welded pipe in the range of large-diameter group spacing are more obvious. In 2004, the output of API5L-B (L245) seamless line pipe was about 400,000 tons. The steel grade includes X42-70, q355gnh steel h beam, and the varieties include onshore line pipe and subsea line pipe.

09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel q355gnh steel h beam has a protective effect against corrosion.

Steel transportation because of the special material of q355gnh steel h beam steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
