ANSI Flanges-manufacture,factory,supplier from China

Difference between ANSI and ASME Flanges?The ANSI and ASME terms are most common in metal industries. But many people still don't know the exact difference between ANSI and ASME. They thought that both ASME & ANSI Flanges are the same and there is no difference between them. But that's not right. In this article, we clearly understand the difference between ANSI and ASME Flanges. ANSI and ASME Flanges are the standard flanges designed with specific rules and conditions stated by ASME and ANSI standards.

Flanges play a very fundamental position in connecting pipes, valves, and different industrial equipment. They furnish effortless get admission to at some point of cleaning, repairs, and inspection. In heavy industry, flanges want to be chosen cautiously considering they can structure a susceptible factor in the system.WHY CHOOSE STAINLESS STEEL FLANGES?You want to get value for your money. Here is why stainless steel flanges are worth the investment.Resistance to CorrosionIn every metal application, corrosion is an important consideration.

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.

SAE / ANSI / AISI 316 is the second most commonly available/widely used type of stainless steel after the SAE/ANSI/AISI 304. Considered the generic workhorse, SS 304 can serve in most situations with great success.

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.

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.

All steels have the identical primary iron and carbon composition, however stainless-steel additionally includes a healthful dose of chromium—the alloy that offers stainless-steel its well-known corrosion resistance.There are a couple of grades known as stainless-steel, every with barely exclusive alloy composition, and consequently barely exclusive bodily characteristics.Stainless metallic need to comprise at the least 10.five percentage chromium.

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.
