- Q:Water, gas, steel pipes, thick steel wire means?
- Water pipes, gas pipes and other collectively known as water gas pipe, generally galvanized steel pipe, so it can be called water and gas pipe. Most of them are welded steel tubes made of low carbon steel.
- Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
- To look at the use of concrete after welding, if the stress is relatively large and thin galvanized pipe wall is recommended to not use welding, if the requirement is not high Po mouth welding should be welding depends on galvanized pipe material selection electrode generally no sealing material are 20
- Q:Heating system DN40 and DN32 welded steel pipe how to connect?
- Is the wire: also called pipe thread connection, the malleable steel pipe fittings, malleable iron is the thread connection using DN40X32 diameter hoop.
- Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
- Carbon steel is relatively alloy steel. Its carbon content is higher than alloy steel, and 20# steel is one kind of carbon steel.
- Q:What time what time for gas pipeline steel pipe PE pipe
- City network is generally medium, are generally. PE pipe high pressure pipe with building the required distance, is generally used around the high pressure pipe laying (high pressure gas supply capacity, and can play the role of peak shaving), the city zone by the supply voltage to the voltage, residential building regulation boxes of low voltage supply to the users.
- Q:What does cathodic protection of steel tubes mean?
- The corrosion of metals causes great economic losses directly or indirectly. Foreign statistics show that every year due to corrosion and scrap metal materials, equivalent to 20~40% of metal production, the world every year due to corrosion and loss of metal reached more than 1 tons.
- Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
- The magnitude of the axial force acting on the steel member is only related to three factors, namely, the strength of the material, the sectional area of A and the longitudinal stability factor of F.
- Q:What quota should be installed for heating seamless steel pipe?
- Should be in low carbon steel welding installation set industrial pipeline engineering quota, material to input the name and type of seamless steel pipe specifications and price; according to the description of the contents of related items can be set.
- Q:What is the difference between seamless steel pipe and welded pipe?
- The thicker the diameter, the more commonly the spiral weld. The seamless steel pipe is generally molten state molten steel through the annular slot backlog, and then stretched and other treatment process, so that there is no weld. On the performance, especially the pressure capacity of the steel pipe than ordinary steel has greatly improved, so often used for high voltage equipment.
- Q:What do you mean by "SC" in welded pipe SC200? What's the diameter of 200?
- 200 refers to the diameter of the pipe. Personally, you should be an electrical professional, but the electrical specialty rarely uses the 200 pipe diameter unless it is used when the buried cable passes the road;
We mainly produces Square and Rectangular Tubes which using the cold rolling technology and other types of tube including Round Steel Pipes, Welded Steel Pipes, Seamless Steel Pipes, Long Products, Flat Steel Products and so on. Our productivity achieves 500, 000 tons each year.
Our company is stronger in financial capital and enough power of technical support. The steel tubes made by the company are strictly according to ISO9001:2000 standard quality management system to ensure the high quality of the products.
