Large Diameter Flat Flange-manufacture,factory,supplier from China

About why wires and cables are twisted:1. Copper wires of different specifications and different numbers are twisted together in a certain arrangement order and laying pitch to become a conductor with a larger diameterThis stranded large-diameter stranded conductor is softer than a single copper wire of the same diameter, and the resulting wire has good bending performance and is not easy to break during a swing test.

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.

Advantages of thin-walled 90-degree elbows: excellent wear resistance and continuous use.90° elbows are suitable for piping systems in petroleum, natural gas, chemical, hydropower, construction and boiler industries.The straight seam elbow with any large diameter and relatively thin wall thickness can be obtained by the casting process. The manufacturing cycle can be shortened and the production cost can be greatly reduced. Because it does not require any special equipment, it is especially suitable for on-site processing of large straight seam elbows.

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.

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.

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.

At present, there are few cases of large area stainless steel curtain wall in the field of building exterior wall. Even if large area is adopted, it often does not pursue its high flatness, but only expresses strong texture.For The Chicago Cloud Gate project, each individual steel plate was CNC machined at the factory, cut with a stainless steel plasma torch 3/8 inches thick, and molded using a coil machine created specifically for the project.

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

Advantages:Forming speed, high yield, can be made into a variety of cross section forms, to meet the needs of the use conditions; Cold rolling can produce large plastic deformation of steel, thus raising the yield point of steel. Hot rolling can destroy the casting structure of steel ingot, refine the grain size of steel, and eliminate the defects of microstructure, so that the microstructure of steel is compact and the mechanical properties are improved.Disadvantages:1.
