Steel U Channels VS C Channels

Like other hollow sections, steel channel is rolled from steel sheet into C or U shapes. It consists of a wide "web" and two "flanges". The flanges could be parallel or tapered. Steel channels are often found in bridges, wall studs, rafters, wooden beams, and beyond. They are known for their strength and durability in construction and other engineering applications. They help support heavy equipment or machines while allowing them to mute out loud sounds and decrease vibrations.

Standards for welded steel pipes and stainless steel welded steel pipes

Welded steel pipe is referred to as welded pipe. It is a steel pipe made by welding steel or steel strip after curling and forming by a unit and a die. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are many, and the equipment investment is low, but the general strength is lower than that of seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip steel continuous rolling production and the progress of welding and inspection technology, the quality of welds has been continuously improved, the varieties and specifications of welded steel pipes have increased day by day, and they have replaced seamless steel pipes in more and more fields, especially in heat exchange spare pipes, decorative pipes, medium and low pressure fluid pipes, etc.

Long Radius Elbow VS Short Radius Elbow

Elbow is a common connector in pipeline system, which is widely used in various industries, such as oil, natural gas, chemical industry, hydropower, construction, etc. The design of elbow includes not only material and angle, but also the choice of bending radius, which directly affects the resistance of fluid flow and the stability of pipeline system. According to the different bending radius, elbow can be divided into long radius elbow and short radius elbow. So, what is the difference between these two elbows? What occasions are they suitable for?

How to deal with the welds and welding points of 304 stainless steel?

Some customers who make mechanical equipment have reported that some equipment has rusted at the welding point after being welded with 304 stainless steel strip argon welding. The reasons need to be analyzed from all aspects, and then the right medicine can be prescribed to find a solution. The following editor will introduce them one by one. Analysis. Welded pipes are made through welding process. The welds of 304 stainless steel pipes will leave orange, blue or black welds after welding, which are difficult to remove. The presence of solder joints not only affects the appearance, but also accelerates corrosion in the atmosphere and reduces the corrosion resistance of the material, which will have a certain impact on actual use. This article will introduce in detail how to deal with welds and welding points on 304 stainless steel pipes for reference only.
