Q:What's the actual size of the DN25?
Steel pipe production technology development began in the bicycle manufacturing industry rise, early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry, petroleum and natural gas drilling and mining and transportation, are promoted in production the quality and variety, the development of steel tube industry.
Q:25 of the steel pipe with 6 in charge of what is the difference?
25 of the steel pipe with 6 in charge of the difference:25 of the steel pipe refers to the DN25 tube, the outer diameter of 25mm; 6, in charge of refers to DN20 steel pipe, the outer diameter is 20mm.
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: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:What are the uses of welded steel pipes?
Ordinary carbon steel wire bushings (GB3640-88) are industrial and civil construction, installation of machinery, equipment and other electrical installation works for the protection of electric wire.
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 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:A333gr6 steel pipe and domestic material of the same?
The SA333 standard in ASME (cryogenic seamless and welded nominal steel tubes), so A333-6 is a representation of the United States, followed by many countries.
Q:How many fasteners are there in a ton of steel tubes?
The fastener generally refers to the intermediate connecting parts connecting two members, in the construction project for external diameter of steel pipe scaffold with 48mm fixation, the fastener is divided into rectangular fastener (cross directional fastener fastener) rotary fastener (universal movable fastener fastener) (a direct docking fastener fastener fastener) etc..
Q:What does "HBB" glass steel pipe mean?
Non electrical corrosion, non-magnetic, suitable for single core cable laying, and steel pipe is a magnetic material, special treatment must be taken to prevent the formation of eddy currents.
