Q:What are the specific differences between flexible pipes and rigid pipes?
Structurally:A rigid waterproof sleeve is welded with a water stop ring outside the steel pipe;The flexible waterproof casing pipe is welded on the outside of the 3 side wing ring, 4 screw buckle, inside a welding piece with a rubber ring, the outside and do a flange, with 4 double head bolt, welding a steel pipe, the pipe installed, the flange is installed. The screw fastening, tightening the apron is bigger, more Water Leakage, generally in the waterproof requirements of relatively high places, such as the pool of water.
Q:Seamless steel tube with the tube with what is the difference?
Seamless steel tube is integrally formed with welded steel pipe steel plate butt welding and welding seam.
Q:What's the difference between straight steel pipe and seamless steel pipe?
The welded pipe is made of rolled steel plates, and small ones are straight welded, and big ones are spiral welded. Because the welded pipe has weld, the mechanical performance of weld is poor, so its applicable range is limited, but its price is cheap. Significant difference is that there are welded pipe, seamless steel pipe is not, of course, the welded pipe treatment of good, layman do not see the difference.
Q:What quota should be installed for heating seamless steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:What are low-pressure carbon steel tubes?
Pipe fittingsA pipe fitting is a piece of pipe that is connected to a pipe. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange fittings and welding pipe four categories. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
First, the surface of the steel pipe is treated by embroidery, which is more durable, not faster than the rapid oxidation, and will not form white rust on the steel tube;Two. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave convex part is protected;
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:How to distinguish between steel pipe and spiral pipe material?
The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:Seamless steel tube 89X4 meters, how heavy?
Generally seamless steel pipe wall thickness will be uneven, according to the theory, each meter is 8.3844 kilograms, but if the wall thickness is poor 20--30 wire, then the weight will increase some
Q:The difference between carbon and welded steel tubes
Quality solutionsThe carbon steels we usually refer to include carbon structural steels and carbon tool steelsThe common steel pipe is divided into two kinds: seamless steel pipe and welded steel pipe. The welded pipe of small size is straight welded, and the big size steel pipe is usually spiral welded
