Q:What does cathodic protection of steel tubes mean?
Applied current: a macro cell consisting of a protected metal piece and an insoluble auxiliary component. The negative electrode of the battery is connected to the metal to be protected. The power supplies the electrons so that the metal is not corroded by missing points.
Q:What quota is reserved for buried DN20 steel pipe?
It is an embedded sleeve control sub item, if the reserved hole, then there is no need to cover, special subject structure adjustment factor of the cost of the water supply and drainage engineering, water supply and drainage engineering he is buried under the charge.
Q:What's the difference between a cracked carbon steel tube and a liquid carbon steel tube?
Test: cracking carbon steel pipe in addition to eddy current testing, but also to do ultrasonic testing, and liquid carbon steel tubes are generally only eddy current testing.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
The pipe material of heating pipe network should be designed according to the requirement. When the design is not specified, the following requirements shall be met:1 when the pipe diameter is less than or equal to 40mm, welded steel pipe shall be used.2 when the pipe diameter is 50 ~ 200mm, welded steel pipe or seamless steel pipe shall be used.3 when the pipe diameter is greater than 200mm, spiral welded steel pipe shall be used.
Q:How can seamless steel tubes be produced?
Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:Are steel tubes and round steel in weight or length when purchased?
A large amount of words is calculated by weight, less is usually calculated. According to the length between the length and quality of a material is usually a scaling. Steel belongs to the section, with the length of valuation, according to the classification of wall thickness and diameter; round steel belongs to building materials, mostly for the amount of weighing per ton of valuation, a small amount of more than according to the length multiplied by the conversion ratio of weight to that theory. But the latter is the valuation of tons of steel products between the uneven thickness, with uniform proportion will produce larger price difference, so the general price of different manufacturers are not the same, mostly depends on the quality, to a certain extent is to balance the diameter difference.
Q:Welded and seamless steel pipe how to distinguish?
Different processing technology:Seamless tubes are made of quality carbon steel or alloy steel. Processing technology of seamless pipe hot rolling and cold drawing is divided into two ways, and the tube is generally based on welded.
Q:What does "steel pipe SC" mean?
DN100 and "SCH80" refer to the outer diameter and the wall thickness of the steel pipe;
