Shortcomings of Duplex Stainless Steel Pipe
1) the universality of the application and multi-faceted as austenitic stainless steel, for example, its use temperature must be controlled at 250 degrees Celsius.
2) its plastic toughness than the austenitic stainless steel low, cold, hot processing technology and forming performance as austenitic stainless steel.
3) the existence of moderate temperature brittle area, the need for strict control of heat treatment and welding process system to avoid the emergence of harmful phase, damage performance.

Common Causes of 304 Stainless Steel Pipe Corrosion
1 Chemical corrosion 1.1 Surface contamination: attached to the surface of the oil, dust and acid, alkali, salt and other under certain conditions into the corrosive medium, react chemically with some elements of stainless steel pipe, chemical corrosion and rust. 1.2 Surface scratches: various scratch destruction of the passive film, reduced ability to make stainless steel protection, prone to chemical reaction medium, chemical corrosion and rust. 1.3 Cleaning: Cleaning is not clean after
How to Detect High Quality Coating Steel Pipe
Coating steel pipe is now a very high rate of a pipe, we racked our brains, in order to allow you to pick a better coating steel pipe to provide you with a test method. 1.Impact test In addition to the appropriate room temperature range, but also in accordance with the relevant national standards, the impact of its operation, in order to see the changes in the coating. 2. Visual inspection This is the
How to Strengthen the Stability of SSAW Steel Pipe
1) Small and medium-sized steel, wire rod, steel, medium diameter steel pipe, wire and wire rope, etc., can be stored in a well-ventilated shed, but must be under the pad. 2) Some small steel, thin steel, steel, silicon steel, small diameter or thin-walled steel pipe, all kinds of cold-rolled, cold-drawn steel and high prices, easy to corrode the metal products can be stored. 3) Storage of SSAW steel pipe(Spirally Submerged Arc Welded
Installation Method of Coating Composite Steel Pipe
General provisions 1, pipeline installation should have the following conditions ① construction drawings and other relevant technical documents complete, and has been technical to the end; ② the installation of the required plastic pipe, fittings and other visual inspection and check the product certification, specifications, variety and quantity; 2, the construction staff should understand the performance of coated steel pipe and the connection, to master the basic operating skills. 3, coated composite steel pipe should

Difference Between Duplex Stainless and Industrial Stainless Steel Pipe
Difference between duplex Stainless steel pipe and industrial stainless steel pipe. 1) Comprehensive mechanical properties better industrial stainless steel pipe, especially plastic toughness, not as industrial stainless steel pipe as brittle sensitive. 2) In addition to stress corrosion resistance, the other resistance to local corrosion is better than industrial stainless steel pipe. 3) Cold processing technology and cold forming performance is much better than industrial stainless steel pipe. 4) Welding performance is also far
Stainless Steel Pipe and Industrial Stainless Steel Pipe
Stainless steel pipe is divided into two series: decorative stainless steel pipe(stainless steel pipe) and industrial stainless steel pipe. Decorative stainless steel pipe(stainless steel pipe(SS)): usually outside the wall will be bright tube, hence the name of thinking, stainless steel pipe(SS) is used for decorative purposes. Stainless steel pipe(SS) mainly used to decorate, such as railings, staircase handrails, windows, etc., the wall thickness is very thin. As with the industrial stainless
