Because of the hydraulic bulging process of stainless steel tee, the equipment tonnage is large, which is mainly used in the manufacture of standard wall thickness stainless steel tee with less than 400. Our country’s transportation facility is the country “Eleven-Five” continues the big investment domain, according to the relevant information, the Ministry of Transportation and the year after tomorrow will invest 1 trillion yuan in norm-building: One is the construction of rural roads, and the other is the construction of major infrastructure including railway transportation, highways and airports: third, the post-disaster reconstruction of earthquake-stricken areas. American Standard flange manufacturers regardless of how much pressure he is a flat product, which we often say. Generally used for flammable, explosive, toxic medium and high pressure occasions. To this end, the foreign steel mills to discuss the use of aluminum and titanium not only the exercise of boron steel, but also steel will be rich in boron and aluminum, titanium, zirconium, manganese, silicon and other elements of the composite boron ferroalloy one-time participation, the practice of better use.
Groove: Groove Equipment using a dedicated elbow groove machine. Elbow fittings used in the material is a large class of special electricity, acoustic, thermal, mechanical, chemical and biological functions of new materials, biotechnology, energy technology and other High-tech fields and national defense construction of important basic materials, but also to transform some traditional industries, such as agriculture, chemical, building materials and other important role. Later, the carbon steel elbow in these enterprises under the impetus of continuous expansion, technology continuous improvement.
The change of the roundness of stainless steel flange Faranne lateral contraction will cause the change of the flange roundness, as the flange length of 4.6. The selection of particle size distribution and slurry concentration ensures that the settling velocity and laminar-turbulent flow rate are less than 1.5/, and that the planning flow rate of the pipeline is within 1.5/~2.0/’s size. Large flange production process has forging and rolling and splicing three kinds.
