pipe elbow

Pipe elbow In the pipeline system,it is used for the connection at the bend of the pipeline,and the elbow is one of the pipe fittings that change the direction of the pipeline.

How many types of pipe elbows for stainless steel elbows and titanium elbows?

According to the actual engineering needs, elbows are divided into angles,there are three most commonly used elbows, 45° and 90° and 180°, as well as other abnormal angle elbows such as 60° and 135°.

Other names of pipe elbows

butt-weled pipe elbows: 90° elbows,right-angle elbows, love bends, stamping elbows, pressed elbows, machine-made elbows, welded elbows, etc. 

Butt-welded pipe Elbow use: connect two pipes with the same or different nominal diameters,so that the pipes can be turned at 90°,45°,180° and various degrees. 

Elbow and elbow: the bending radius is less than or equal to 1.5 times the pipe diameter is an elbow, and greater than 1.5 times the pipe diameter is an elbow. The connection method is directly welded, flange connection, etc. 

Elbow classification: welding elbow,stamping elbow,pushing elbow,forging elbow,steel coil welding elbow, etc. 

Pipe elbow tech requirement as below:

1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, leaving a certain angle and with a certain edge. This requirement is also relatively strict, how thick the edge is, the angle and deviation The scope is specified. The surface quality and mechanical properties are basically the same as the tube. For the convenience of welding, the steel grade and material of the pipe fittings and the connected pipes are the same.

2. That is, all pipe fittings must be surface treated, the oxide skin on the inner and outer surfaces is sprayed off by shot peening, and the carbon steel elbow is coated with anti-corrosion paint. This is for export needs, and in China, it is also to facilitate transportation and prevent rust and oxidation. Work in this area must be done.

3. It is the requirement for packaging. For small pipe fittings, such as export, it needs to be a wooden box, about 1 cubic meter. It is stipulated that the number of elbows in this box should not exceed about one ton. The standard allows sets, that is, large sets are small, However, the total weight should generally not exceed 1 ton. For large y, it needs to be packaged in a single package, such as 24″, it must be packaged in a single package. The other is the package mark, the mark should indicate the size, steel number, batch number, manufacturer’s trademark, etc.

Titanium elbows and stainless steel elbows

Titanium elbow has strong corrosion resistance, high strength, low density, high hardness, high melting point, and strong corrosion resistance; high-purity titanium has good plasticity, but becomes brittle and hard when impurities exist. Usually used in power station, chemical, petroleum and other equipment materials. The weld-ability of stainless steel elbows is poor, and attention should be paid to the welding process, heat treatment conditions and the selection of suitable electrodes. 

Stainless steel elbows have certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance. Usually used in power station, chemical, petroleum and other equipment materials. The weld-ability of stainless steel elbows is poor, and attention should be paid to the welding process, heat treatment conditions and the selection of suitable electrodes. 

Whether it is stainless steel or titanium elbow, the two ends of butt welding elbow generally need chamfering,which is convenient for welding Welcome to contact us to purchase titanium elbow and stainless steel elbows
