Press release from: Hunan Great Steel Pipe Co.,Ltd

Anti-corrosion steel pipe refers to do anti-corruption treatment for the ordinary steel pipe with special technology, making the steel pipe equipped certain corrosion resistance.Generally used in waterproof, anti-rust, acid and alkali proof, anti-oxidation and so on.Different needs, different inside and outside wall corresponding anti-corrosion measures.Common are: epoxy coal tar anti-corrosion, anti-corrosion epoxy coatings, urethane paint anti-corrosion, IPN8710 water pipeline corrosion protection, non-toxic paint anti corrosion,anti-corrosion polymer coating, steel pipe lining anti corrosion cement mortar, etc.Anti-corrosion steel pipe is mainly used in special requirement or engineering field with bad environment.According to the steel pipe using location can be divided into the outdoor steel pipe anti corrosion and buried steel pipelines anti corrosion.The ground: special surface coating anti-corrosive paint is still the main method of steel construction and rack anti-corrosion. Anti-corrosive paint protection function can be divided into the primer, middle paint and top paint, all the layers of paint have its characteristics, individual,several layers together, forming a composite coating, improve the anti-corrosion performance and prolong service life.Underground: the corrosion reason of outer wall is more complex, such as soil corrosion and stray current corrosion, microbiological corrosion and so on, should choose a kind of good insulation,chemical stability, resistance to plant roots antimicrobial antiseptic material. Buried steel pipeline outer wall corrosion mainly is electrochemical corrosion, coating anti-corrosion layer in the outer wall of pipe is the most commonly used method. The outer coating can reduce or block the corrosion current and slow down the corrosion. Suggest using epoxy coal tar anti-corrosion, there are national standard to depend on.Coating steel pipe is formed with plastic on the high-frequency welded steel pipe and large diameter spiral welded pipe, the most great outer diameter of 1200 mm. According to the different needs, coating polyvinyl chloride (PVC), polyethylene (PE), epoxy resin (EPOZY), and other various plastic coating performance, with good adhesion and strong corrosion resistance, can resist the corrosion of strong acid, strong alkali and other chemical corrosion, non-toxic, no rust, wear resistance, impact resistance, strong resistance to permeability, smooth pipe surface, no adhere to any materials, can reduce the transmission resistance, improve the efficiency of traffic and transportation, reduce the pressure loss.Coating without solvent, no leakage material, so that it can't pollute the conveying medium, so as to ensure the purity of fluid and health, in 40℃ to + 80℃ range can be used with cold and heat cycles, not aging, not cracking, thus it can be used in cold zone and other harsh environment.Large-diameter coated steel pipe is widely used in tap water, natural gas, petroleum, chemical industry, medicine, communication, electric power, ocean engineering, etc.

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
Shortcomings of Duplex Stainless Steel Pipe
Compared with austenitic stainless steel pipe, duplex stainless steel pipe's shortcomings are as follows: 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
