Hengtong supply Q235 carbon steel head PN2.0 DN800 BW butt heads (Contact: Ma Yuanyuan Contact: 18,732,703,585 QQ: 619 688 609 Company Website: http://www.czhypipe.com/) head container components (see below), depending on the geometry, can be divided into spherical, oval, dish-shaped, spherical cap, conical shell peace cover several, including spherical, oval dish, spherical cap-type head and collectively, a convex head. Divided into butt welding head, socket welding head. Equipment used in a variety of containers, such as storage tanks, heat exchangers, tower, reactor, boilers and separation equipment. Made of carbon steel (A3, 20 #, Q235, Q345B, 16Mn, etc.), stainless steel (304,321,304 L, 316,316 L, etc.), alloy steel (15Mo3 15CrMoV 35CrMoV 45CrMo), aluminum, titanium, copper, nickel and nickel The alloy head petrochemical, atomic energy to food pharmaceutical and many other industries important and indispensable part of the pressure vessel equipment. The cap is on the cover of the pressure vessel, a pressure vessel pressurized parts. The role played by the sealing action. One is made of the upper and lower end of the pot-shaped pressure vessel, pipeline coming to an end, is not prepared to extend forward, live it with a head tube is sealed with the form of welding. And the role of the head almost blind plate and cap, but that the two products can be dismantled. Weld the head can not be demolished. Ancillary fittings are pressure vessels, piping, flanges, elbows, tees, Stone and other products.
