Large diameter steel large diameter head head head of large diameter 304 stainless steel large diameter flat head

[Large diameter head] a basic description of the genus head boiler pressure vessel components. Is usually used at both ends of the pressure vessel. Then there is to do at the end of the pipe to block the use of a welded pipe products. There are many forms. Head】 【large diameter, depending on the geometry of the product characteristics can be divided into spherical, oval, dish the ball crown-shaped, conical shell peace cover several, which spherical, oval, dish, spherical cap-type closure Head also referred to as the convex head. Divided on the butt welding head, socket weld head. Equipment for a variety of containers, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment.

Products received by customers throughout the country. [Head] large diameter carbon steel head belongs to a basic description of the boiler pressure vessel components. Is usually used at both ends of the pressure vessel. Then there is to do at the end of the pipe to block the use of a welded pipe products. There are many forms. [Head] large diameter carbon steel product characteristics into butt welding head, socket weld head. Equipment for a variety of containers, such as storage tanks, heat exchangers, towers, reactors, boilers and separation equipment. Materials are carbon steel (A3,20 #, Q235, Q345B, 16Mn, etc.), stainless steel (304,321,304L, 316,316L, etc.), steel (15Mo3 15CrMoV 35CrMoV 45CrMo), aluminum, titanium, copper, nickel and nickel alloy. My company has three production lines elbow, two tee IF Bend diameter pipe production line production line, pipeline flange forging an all products are used by the US standard ASME (ANSI) German standard DIN, Japanese standard JIS, Chinese GB / T , JB, SH, HG and other standards. Specializing in the production of seamless straight seam steel pipe exports (90 degrees 45 degrees 180 degrees elbows, tees, crosses, reducers, elbows, flange, pipe caps, IF Bend, custom processing diameter 10mm --- 426mm variety of Big Bend .U Z-bend-bend S-bend etc. flange (high pressure welded flange, welded flange ,, flange cover), pipe materials are selected domestic carbon steel, stainless steel, alloy steel materials such as:. WPB Q235, Q345B, 20 #, 35 #, provide 12crlMov, 16Mn, 15crMo, 321,304,316,316L other high-quality materials production and processing, according to customer drawings making head is a part of the container According to different geometries, can be divided into spherical, oval, dish, of spherical, conical shell cover and other types of peace, where spherical, oval, dish, of spherical head also referred to as the convex closure head. used in a variety of containers equipment, GB150 and relevant head standard definition is not reasonable thickness, mainly in the container and head after forming thickness requirements for forming convex head thickness and thermal requirements shall reel less than the nominal thickness of cut steel plate negative deviation (δn-C1), which may lead to the design and manufacture of twice the thickness increasing the thickness of the basic design of the forming thickness to ensure this end, have proposed the concept of a minimum thickness of forming:. "HRC After the cylinder head or convex forming process need to ensure the thickness, its value is not less than the design thickness. "That is the name of the designer should be marked on the drawing and the minimum thickness forming thickness (ie design thickness δd), which makes manufacturing units decide whether to manufacture thinning amount plus rounded amount depending on the design and manufacturing process of the original design. is head of the spherical cap formed part of a spherical shell with hemispherical head and no hemming ball of head types The pressure vessel use more hemispherical head as head end, the advantage is in the same volume under the surface area of ??the minimum required thickness under the same pressure conditions thinnest, from saving material and strength point of view, is the most reasonable. No discount side spherical head and Simplified connection with the fillets in the middle head is often used as a container receiving chamber of two independent, but also for the end of the head. ball head in occasions of attention points made by Cangzhou in Victoria Tube Co. released, says: 1. Carbon steel ball-type head will crack occurs in nitrates, ammonia, sodium and other alkaline environment, in order to eliminate residual head when stress 2. Description of austenitic stainless steel in chlorine. can occur under certain circumstances ion stress corrosion cracking, select the appropriate materials in the design ball head. 3. need galvanized or aluminized carbon steel container, do first heat treatment, to remove residual stress.
