Specifications of Steel Pipe Clamps

Steel pipe clamps are pipe clamps made of material stainless steel or carbon steel, mostly used to clamp the metal pipes and tubes to provide fastening and support for the pipes and tubes. When people install the tubes and pipes, normally they need certain types of pipe clamps.

Steel pipe clamps some times are known as metal pipe clamps also. There are many different types of steel pipe clamps designed according to different standards. The most popular specifications of the steel tube clamps are German standards, such as:

There are two types of DIN 3567 steel pipe clamps, one is designed to DIN 3567 -A, which is known as the 2 bolts flat steel pipe clamps; and the other is designed to DIN 3567-B, which is known as the 3 bolts steel pipe clamps.

Here below is the specifications (data sheet) of DIN 3567-A steel pipe clamps and DIN 3567-B steel pipe clamps. Continue reading →

What is hydraulic ball valve?

Hydraulic ball valves are usually a kind of special stainless steel ball valves or carbon steel ball valves which are used in hydraulic industry, to control the fluid in the hydraulic systems.

As hydraulic ball valve is one sub category of the ball valves, so to explain what is hydraulic ball valve, we need to explain what is ball valve first.

What is ball valve?

Ball valves, as its name suggests, are stop valves that use a ball to stop or begin a stream of fluid. The ball (see in the below drawing) performs the exact same function as the disc in other types of valves. Since the valve handle is turned to open the valve, then the ball rotates into some stage where a part or all the hole through the ball is in line with the valve body enter port and export, permitting fluid to flow through the valve. After the ball has been rotated so the hole is perpendicular to the flow openings of the valve body, the flow of fluid ceases. Continue reading →

What is Butt Weld Flange and its applications?

Butt weld flanges are widely used in different industries, this is one of the popular type of industrial flanges. The range of use is determined according to different characteristics. They are mostly used in the case of moderate medium conditions, such as low pressure non-purifying compressed air and low pressure circulating water. Its advantage is that the price is cheaper. Butt weld flanges are suitable for connection of steel pipes whose nominal pressure does not exceed 2.5MPa. The sealing surface of butt weld flanges can be made into three types of smooth, concave and convex. Smooth butt weld flange application of the largest amount, the other two methods of butt weld flange is also common in use.

Butt Weld flange is not easily deformed, with well sealed, so they are widely used. They have the corresponding rigid and elastic requirements and a reasonable butt welding thin transition, welding seam from the joint surface distance, so the joint will not be affected by the welding temperature deformation. They have a more complex body structure, so they are suitable for pressure or temperature fluctuations in the pipeline or high temperature, high pressure and low temperature pipe, generally used for PN greater than 2.5MPa pipe and valve connections; also used to transport prices Expensive, flammable, explosive medium on the pipeline.

What is the reason of flange seal failure? How to prevent flange leakage?

Analysis of leakage of flange seal  and its Prevention 

Abstract: By analyzing the causes of leakage of flange seal, find out the prevention and solution.

Key words: flange  seal  leakage

Flange connection is widely used in the pipeline connection, such as  in gas, oil, water supply and drainage pipes. There many different types of flanges such as SAE flanges (code 61/62 flanges), Slip on flanges, Lapped flanges, Weld neck flanges, and so on.

As the leakage of flange seal can cause the transmission of materials, gas leakage, pollution, and even cause a major fire or personal injury accidents, it must pay attention to the flange seal. This paper analyzes the factors that cause leakage of flange  and puts forward the solution to the solution.

First, the flange

1,  Sealing surface of flange exists in several forms

(1) Flat sealing surface is a smooth plane, usually in the plane with 2-3 concentric groove, tighten the bolt, the gasket material is easy to both inside and outside the squeeze, not easy to compact, only for the pressure is not high , Non-toxic media, non-flammable and explosive occasions.

(2) The concave-convex sealing surface consists of a concave surface and a convex surface, this sealing surface gasket is easy to center, when compress it ,the gasket will not squeeze out.So it can be used for slightly higher pressure occasions.

(3) The tongue and groove sealing surface consists of a tenon and a groove surface, the gasket placed in the tank, will not be squeezed and moved, because the gasket is narrow, the gasket clamping force correspondingly smaller, its shortcomings is the complex of structure and manufacturing , replace the gasket is also more trouble. Generally used for flammable, explosive, toxic media and high pressure occasions. Continue reading →

What are the advantages of stainless steel tube heat exchangers and brass tube heat exchangers?

AS many people may know there are two typical types of tubes to constructing heat exchangers, which are seamless stainless steel tubes (including duplex stainless steel tubes S31083, 2205, S32750, 904L, etc) and brass tubes. But what are the advantages and disadvantages of this two different heat exchangers?

Stainless-steel-heat-exchangers-compared-to-brass-tube-heat-exchangers

In fact, the biggest difference is not the heat transfer performance, corrosion resistance is good or bad, but is that copper tubes are less prone to fouling than stainless steel tubes, which many people might do not realize. To give a simple example, some commercial boilers are used without water treatment equipment, but using life is as long as 15 years. The reason is that although the water can foul scale in the copper wall, but it is only flocculent fouling, in this case, as long as we increase the flow of water, fouling scale can not precipitate down.
