In the pipeline system, elbow is a pipefitting applied to change the direction of pipeline.   Elbow Categories: 1. Materials: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, etc.   2. Manufacturing methods: pushing, pressing, forging and casting, etc.  ...

Put liftout attachment on the pipe, which includes a metal, transformer, commutator, bracket, etc.; heat the metal bar, when you use jacks and metal bar to push out, the outward wall materials naturally come out to reduce tee blank; then weld a pipe section with certain length and specification on the...

This technical article introduces some knowledge of the transportation and machining of stainless steel pipefitting. 1. When transport stainless steel pipefitting, it cannot be contacted with other metal, which needs plank or rubber plate.   2. Stainless steel pipe fitting arc starting and stopping...

This technical article introduces the molding technology and basic process of GB elbow.   First weld a cross section of a polygon or multi ring shell whose both ends is closed, and when its internal is filled with medium pressure, with internal pressure the polygonal will gradually become round,...

GB elbow has certain anti-corrosion (oxidizing acid, organic acids, cavitations), heat-resisting and wear-resisting performance. It is usually used in power plant, chemical, oil and other equipment materials. GB elbow has poor weld ability, which should be paid attention to welding and heat...

This technical article indicates eight tips of stainless steel pipefitting transportation and process. 1. The convey of stainless steel pipefitting materials cannot be connected with other metal, which should be added some non-metallic materials such as plank or rubber sheet.   2. The arc starting...

Butt welding elbow material is a core in the field of new materials, which plays an important role in promoting and supporting the development of high and new technology. In the global research of new materials, wear-resistant materials account for about 85%. Butt welding elbow in use process often...

Stamping elbow, whose full name is stamping welding elbow, is produced through using pressing tool to make the board having the same material with the pipe become a half block of annular elbow and then weld the two half elbow together. Due to the difference of various pipe welding standards, and site...

Stainless pipe cap,is also known as pipe plug or pipe cover. The major function of pipe cap is welded in pipe end to cover the pipe with the same function as pipe plug. A pipe cap consists of these parts: convex cap, cone shell adjustable segment, flat lid and tighten port.   The major types of...

The major difference between stainless steel elbow and carbon steel elbow lies in their material. The stainless one has the chemical composition to keep elbow away from being rusted and corroded.   There is something should be taken into consideration when using and maintaining stainless steel...
