ERW Steel Pipe

 Most common seen boiler steel tube can be devided into two kinds, one is midium pressure boiler tube, the other is high pressure boiler tube. Please kindly note that most of high pressure boiler tube are made from seamless steel pipe, welded steel pipe isn’t suitable for high pressure bolier steel tube. Boiler tube has been widely used at heat exchanger pipe and tubing services, high pressure boiler,petrochemical industry pipes, tube exchanger bundle, economizer, super heater, etc. Based on different working temperature, the medium or high pressure boiler tube shall be used. Normally classified as below cases: The operation temperature of general boiler pipe is lower than 450 ℃ . The medium pressure boiler tube mainly adopts hot rolling process or cold drawing process. High pressure boiler tube are often used in high temperature and high pressure working conditions. Under the action of high temperature flue gas and steam, the pipe will occur oxidation and corrosion. It is required...

 We, Xinyue Steel Group have export thousand tons of adjustable steel props to middle east, south Africa, south America, etc, in 2017. Adjustable steel props is widely used in all kinds of construction projects. We’ll have a brief introduction about adjustable steel props’ application, components, surface treatment, advantages. Application: used for vertical supporting of slab framework and beam, for any shape building construction, foe different height of buildings within its range. Components: adjustable vertical pipe support include inner tube, prop base plate, prop nut, prop thread and lock pin. Surface treatment: dipped painting, powder coated, galvanized. Advantage: 1. Simple and reliable structure 2. Easy to erect and dismantle 3. Strong loading capacity 4. Economical construction equipment 5. Easy to get through 6. Length adjustable. http://www.tjxysteel.com/news/Adjustable-steel-props-194.html

 Anti-corrosion steel pipe is widely applied to prevent or mitigate the steel body from corrosion phenomena during the transportation and use of the pipes. Anti-corrosion steel pipe mainly used in pipeline projects in petroleum, chemical, oil and natural gas, heating, sewage treatment, water, bridges support area. These type of pipes is widely applied to anti-corrosive steel facilities, petrochemical, industrial and mining enterprises in the construction industry, various types of tanks, transport pipeline, etc. Specification:Outside Diameters: 219mm~3080mm, Wall Thickness: 6mm~40mm Application:Widely used in oil pipelines, gas pipelines, heating pipes, water pipes. There are many categories of corrosion media for bare steel pipe, such as acid, alkali, salt, oxidants and water vapor. The coating of steel pipe must be chemically inert, acid salt corrosion, structure compact, waterproof permeability, adhesion, tough fullness. A Guide to FBE Coating Apply electrostatic spraying techno...

 There are three main connection methods when connecting galvanized pipes, namely wire type, welding type and rolling groove type. 1. If the thread type method is used, the thread buckle cannot be in complete contact with the pipe hoop of the steel pipe, otherwise it is likely to become loose. Before connecting, it is necessary to measure whether the wall thickness of the steel pipe can reach the standard thickness of the thread. If the thread of the steel pipe does not match the thread of the pipe hoop and cannot be connected, the pipe hoop should be replaced or the equipment should be adjusted to re-thread the thread. 2. Use the welding method to connect. After the galvanized steel pipe is connected, there is a problem that the pipe is not in a straight line and the steel pipe has an oblique opening. The pipe head of the steel pipe should be cut off for a short period before processing;If the two nozzles of the galvanized steel pipe are not tightly butted after the nozzles are bu...

 1.Improve the anti-corrosion conditions of the medium In order to improve anti-corrosion conditions, the following two methods can be used for cs seamless pipes. ①Remove harmful components in the medium. For example, boiler water is heated to boiling, and then the oxygen is removed before use. ②Add corrosion inhibitor. Corrosion inhibitor is a substance that can slow down the corrosion rate. Adding corrosion inhibitor is a common and effective anti-corrosion measure. Different corrosion inhibitors are only effective in certain environments. 2.Using electrochemical protection ①Using the applied current to make the metal to be protected become the cathode. This method only consumes the energy of the applied current, and is often used to protect underground pipelines and equipment, offshore oil platforms, sea ships, iron tower feet, metal structures working in an environment with water and weak electrolysis, etc. But in strong acid electrolytes, Using this method to protect the steel...
