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.

Seawater corrosion resistant materials, and widely used in Marine engineering. However, in practical engineering application, the stainless steel connection, especially the welding area, often appears various corrosion damage, resulting in a great loss. Therefore, in this paper, according to the characteristics of seawater corrosion of stainless steel, the seawater corrosion and anticorrosion mechanism of its weld site were comprehensively analyzed and studied.

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.

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.

Material grade: ER70S-6Standard: ASMEIt belongs to copper-plated low-alloy steel gas shielded welding wire. It uses C02 or argon-rich shielding gas for welding. It has excellent welding process performance, stable arc combustion, less spatter, beautiful weld shape, and low sensitivity to weld metal pores. The position welding process is good.

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.

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.

OverviewThe concept of super austenitic stainless steel includes super ferritic stainless steel and super duplex stainless steel. A typical example is a super austenitic stainless steel containing 6% molybdenum and 7% molybdenum. These steel grades are specially developed for harsh industries such as petrochemical, chemical, paper and offshore systems.Development of Super Austenitic Stainless SteelTo deal with post-weld austenite intergranular corrosion susceptibility, titanium and tantalum were added early as carbide stabilizing elements.

Common stainless steelsThe  maximum not unusualplace stainless-steel grades are 304 and 316. The key distinction is the addition of molybdenum, an alloy which appreciably complements corrosion resistance, specially for extra saline or chloride-uncovered environments.316 stainless-steel carries molybdenum. 304 stainless-steel does not.For out of doors fixtures like rails and bollards, stainless-steel is a great corrosion-resistant material, however it's going to simplest face up to long-time period publicity if the grade is suitable for its environment.
