Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The thread of the tightening (JDG) joint is unified with an outer thread, a wall thickness of 1.5mm, and a button (KBG). The thread of the joint is an internal thread, and the wall thickness is 1.0mm. Withholding type joint for the use of the same company and pipe connection to matching products with complete connection clamp buckle. Fastening and pressing type correctly connected and locked after no need to do a cross ground.
Q:Welded and seamless steel pipe how to distinguish?
Different price:Because the production process of seamless steel tube is more complex, so the price is more expensive than a seamed steel pipe, and pipe joints mainly adopts steel (steel) two welded, fixed price, the most widely used are.
Q:How to make the magnetic steel, can be like a magnet?
Of course, not all materials can be magnetized, austenitic stainless steel will not do.
Q:What is the theoretical weight per square meter of the steel pipe diameter of the outer frame and the thickness of the tube wall 3mm 48mm?
Formula: outside diameter - wall thickness * wall thickness *0.02466=, weight per meter! : 48-3*3*0.02466=3.3291
Q:What are the advantages of PVC pipe and galvanized steel pipe?
This is different in different fields, in fact, the combination of PVC pipe and galvanized steel pipe becomes plastic steel pipe.The steel plastic pipe is in the internal and external combined with a layer of plastic pipe material and obtained a pipe, it has high mechanical strength, the steel pipe has the advantages of high impact resistance, and corrosion resistance of plastic material, has the advantages of high and low grade health fluid resistance and scaling.The steel pipe used by our company is produced by Benxi Steel, which is well known both at home and abroad. It has the advantages of low phosphorus, low sulfur and high mechanical performance. It can meet the requirements of users.
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel pipe mainly because of anti-interference and electrical connectivity, to prevent other strong magnetic strong signal interference weak signal, while in the electrical connection, galvanized steel pipe can be directly connected to the bridge.
Q:Is the PVC tube a plastic tube or a plastic tube?.
It's plastic tubePolyvinyl chloride (Poly, Vinyl, Chloride, PVC)PVC is a VCM monomer (vinyl, chloride, monomer), in peroxide, azo compounds and other initiators;
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
Q:Why can't stainless steel be put together with carbon steel tube?
The bimetallic corrosion is terminated only when one of the three conditions is changed. Galvanic corrosion is related to the contact area of bimetal and the greater the contact area. Corrosion is less. The driving force of galvanic corrosion is the potential difference.[galvanic corrosion] refers to two or more than two kinds of electrode potential of metal in the corrosive medium, and contact with each other caused by electrochemical corrosion, also known as contact corrosion or double metal corrosion.
Q:What does "HBB" glass steel pipe mean?
Good water resistance, can be used for a long time in wet or water, and the ordinary composite is not water resistant, can only be used in dry environment.Heat resistance, fire resistance is superior to epoxy, glass fiber reinforced plastics and plastic and other materials. It can be used at 130 degrees for a long time, and not burned in case of fire.The utility model has the advantages of insulation, corrosion prevention, no rust, long service life, etc.. Generally up to 50 years, without maintenance.Simple and convenient installation and construction, because this product is light weight, high strength, laying construction method can properly solve the excavation due to road construction, exposed for a long time, prominent problems of city traffic, to achieve the excavation backfill pavement, buried at night, can normal traffic during the day.
