DIN2642 PN10 Pressed flange loose flange-manufacture,factory,supplier from China

Loose flange: This kind of flange is often used in the case where the medium temperature and pressure are not high and the medium nozzle is highly corrosive. The loose flange is generally used in combination with the flanging short joint, that is, the flange ring is loosely sleeved outside the flanging short joint, the pipe is butt welded with the flanging short joint, and the flange sealing surface is processed on the flanging short joint.In addition, there are flat welding ring and butt welding ring plate loose flange.

Implementation principleThreaded flange is a kind of non-welded flange, which processes the inner hole of the flange into pipe threads, and is matched with the threaded pipe to realize the connection. Compared with the flat welding flange or the butt welding flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used on some pipelines where welding is not allowed. Alloy steel flanges have sufficient strength, but are not easy to weld, or the welding performance is not good, and threaded flanges can also be selected.

Structural features:Threaded flanges manufactured in accordance with ASME B16.5 are similar to sliding flanges, but the holes shall have tapered pipe threads in accordance with ASME b1.20.1. The thread shall be concentric with the axis of the flange opening, and the alignment deviation (perpendicular to the flange face) shall not exceed 5mm per meter. Threaded flanges are NPs 1 / 2 to NPs 24 in size and pressure classes are 150, 300, 400, 600 and 900. The sizes of class 1500 and 2500 are NPs 1 / 2 to NPs 2 - 1 / 2.Class 150 threaded flange has no counterbore.

Features of Flat Welding FlangesWhen welding flat welding flanges, only one side welding is required, and there is no need to weld the inner port of the pipe and flange connection. The welding installation of butt welding flanges requires double-sided welding of the flanges. Therefore, flat welding flanges are generally used for low and medium pressure pipelines, and butt welding flanges are used for the connection of medium and high pressure pipelines. Butt welding flanges are generally at least PN2.5MPa. Butt welding is used to reduce stress concentration.

There are a lot of products in life are made of stainless steel, and what are the thickness of stainless steel plate?Stainless steel has different classification, such as some cold rolled model, its thickness is large and small, such as the thinner is 0.3-0.7 mm, slightly thicker  reached 1.0, 1.2, 1.5 mm, and some thicker is 2.0, 2.5, 3.0 mm.

First, the marine fieldWhether it is in the search work on the seabed, or in the application and promotion of products, the use of stainless steel bars can achieve a good anti-corrosion effect. We all know that if steel products are placed in water, it is easy to rust, especially when iron products and seawater are in contact with the impact of oxidation, it is easy to cause rust and other bad conditions. Therefore, in the face of this phenomenon, it can be applied by selecting stainless steel materials.

Why doesn't stainless steel rustBecause of the addition of 12.5% chromium in stainless steel composition, it can make stainless steel surface generated a layer of passivation film, prevent the metal matrix is destroyed, enhance corrosion resistance, so the surface will not rust.

How to identify the quality of stainless steel sinks?1. Thickness of water tank steel plate: The high-quality water tank adopts imported 304 stainless steel plate with a thickness of 1mm, while the ordinary low-grade water tank adopts 0.5mm-0.7mm. The method of identification can be determined from the weight and whether the surface is flat.2. Anti-noise treatment: The bottom of the high-quality sink is sprayed or glued with rubber sheets and does not fall off, which can reduce the sound caused by the impact of the water from the faucet on the bottom of the basin, and play a buffering role.3.

Stainless steel can be roughly divided into flat steel and concave-convex steel. The flat steel plate can be divided into three categories: mirror steel plate with surface light reflectivity greater than 90%; The reflectivity is 50%~90% of the light plate; Matte steel plate with reflectivity less than 50%.
