Stainless Steel Flat welded ring 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.

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.

 In recent years, the stainless steel welded pipe market has been a "big hot". Because of its good heat transfer performance, it is widely used as a stainless steel heat exchange tube. Looking forward to the development trend of 316L stainless steel welded pipe. 　　First, the carbon content of 316L stainless steel welded pipe is 0.03, which can be used in applications where annealing after welding and high corrosive requirements are not possible. 316L stainless steel welded pipe has corrosion resistance due to the addition of molybdenum.

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.

Stainless steel profile and flat steel made in ChinaStainless steel profile belongs to a kind of stainless steel profile, its shape can be divided into many kinds, the most common for Angle steel, flat steel, channel steel and so on.       Stainless steel flat is rectangular steel with slightly pure edges. Stainless steel flat steel can be semi-finished steel. There are cold drawn polished stainless steel flat and hot rolled acid white sandblasted stainless steel flat.Mainly divided into equilateral and unequal two categories, equilateral also known as stainless s

It’s important for those in the metal and steel worlds to recognize that even some products named similarly will be different in their detailed characteristics, and a good example here is welded metal tube versus seamless tube. Both forms of metal tube, these formats are actually very different and will have varying common applications for their use. we’re proud to offer several options when it comes to steel tube for any project, whether a bulk order or a smaller one, from manufacturing through processing and several other needs.

Pattern welding is a special way of constructing a sword blade from a lot of iron / steel parts. Many different kinds of iron / steel parts are fire welded in such a way that a pleasing pattern can be observed on one or both sides of a blade.

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%.
