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.

Recently, the price of stainless steel 904L has fluctuated more frequently. Supported by many factors such as raw materials and inventory, the price center has basically maintained an upward movement. The demand release situation is good, and the overall social inventory shows a downward trend. The stainless steel market is still running at a high level, and the spot transaction volume has increased. The price of raw materials has risen, but the overall market is not as calm as in 2016-2017.

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.

When selecting stainless steel in corrosive environment, in addition to having a detailed understanding of the specific service conditions of stainless steel, the main factors to be considered include: corrosion resistance, strength, toughness and physical properties, processing, formability, resources, price and difficulty of obtaining.Corrosion resistance includes rust resistance and resistance to acid, alkali, salt and other corrosive media, as well as oxidation resistance, vulcanization, chlorination and fluorination at high temperature.

Since the end of July this year, the prices of all metal materials have begun to rebound and prices have risen.So, what other factors affect the price ups and downs besides raw materials?First of all, the composition of stainless steel, that is, stainless steel raw materials, stainless steel raw materials are mainly iron, chromium Cr, nickel NI, the price of these raw materials has played a decisive role in the price of stainless steel.

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.
