gd55光大彩票1、 Equipment name: pipe fittings (welding elbow, welding tee and cross, welding reducer, quick assembly elbow, quick assembly tee and cross)

gd55光大彩票2、 Specification and model: hdn

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

In order to transport liquid, all kinds of pipes must be used. In addition to the straight pipe general steel pipe, various pipe fittings should be used: elbows must be used when the pipe bends, the big and small head should be used when the pipe diameter is changed, and the three-way four-way pipe fittings should be used when bifurcating. The equipment of our company adopts SUS304 stainless steel pipe fittings. The inner and outer walls of the pipe fittings should be smooth, and there are no bubbles, cracks, obvious marks, depressions, etc Uneven color and decomposition color line, pipe ends should be cut flat.

5、 General knowledge of metal materials:
Metal materials are the most widely used materials in our daily life and industry. They are mainly divided into steel, iron and non-ferrous metals. Among them, steel is the most widely used material. The main component of steel is iron, and the rest are alloy elements and various impurities added artificially. It is because of the variety and quantity of these added alloying elements that a variety of steels are formed, such as ordinary carbon steel, stainless steel, alloy steel and so on. Among these added elements, carbon (c) plays a very important role.

6、 Chemical elements:
In addition to the iron element (FE), which accounts for the majority of all kinds of steels, it usually contains the following elements (commonly referred to as alloy elements in steel)

C, Si, Mn, P, s, Cr, Ni, Mo, Ti, V, etc. In general, P and s are impurities, the lower the steel quality, the better.

◇ Material:

This mainly refers to circular pipe, which can be divided into welded pipe (straight seam welded pipe, spiral welded pipe) and seamless pipe. Welded pipe (also known as seamless pipe) is usually used for pipes with low pressure (20kg / cm? 2). Among them, spiral welded pipe is mainly used for large diameter (such as dn400 or above) system. Therefore, its wall thickness is generally thin (usually less than sch10), and seamless pipe is generally used for pipeline with high pressure Due to the limitation of pipe production process, the commonly used industrial seamless pipe is usually hot rolled, so the wall thickness of seamless pipe can be hot rolled. For a certain diameter of pipe, there is usually a certain off-line (generally higher than sch10).

gd55光大彩票8、 Stainless steel fittings:

Stainless steel pipe fittings belong to a kind of pipe fittings. They are made of stainless steel, so they are called stainless steel pipe fittings. They include: stainless steel elbow, stainless steel tee, stainless steel four-way, stainless steel reducer, stainless steel pipe cap, etc. according to the connection method, they can be divided into socket type stainless steel pipe fittings, threaded stainless steel pipe fittings, flange stainless steel pipe fittings and welded stainless steel pipe fittings. The stainless steel elbow is used for the turning of pipe fittings, the stainless steel cross pipe is used for the gathering place of four pipes, and the stainless steel reducing pipe is used for the connection of two pipes with different diameters. Main stainless steel materials: 304, 304L, 316, 316L.
