Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:Welded and seamless steel pipe how to distinguish?
Generally, careful observation, can see traces of the weld seam pipe, further is the determination of the polished incision, and then with the file can be seen there is no clear cut, interface traces with the file cleanup to remove when cutting was pasted interface.
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
There are two kinds of hot dip galvanizing, zinc plated and non galvanized. The flowers must be hot-dip galvanized, without flowers, similar to galvanized.
Q:Can galvanized pipe be welded with seamless steel tube? What should I do to connect?
See the galvanized pipe and seamless steel pipe steel that differences in how if the difference is too large then the steel used for two kinds of materials for welding requirements is not the same, do not recommend direct welding, low pressure can be used in high voltage wire, welding on both sides of the same material flange with flange connection.
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
Seamless steel pipe: a pipe with a hollow cross section, used as a conduit for transporting fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:Where is a steel pipe casing usually used?
A straight tube of carbon steel sheathed on pipes and tubes and threading tubes to protect the joints from damage by electric welding. The purpose is to protect the wires and cables.
Q:What's the gate number of the precision steel pipe?
Precision steel pipe refers to the high precision steel pipe, the wall thickness and internal and external diameter can be controlled within 10 wire tolerance range
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.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:Is it good to buy a simple wardrobe or a steel pipe?
Therefore, the simple solid wood wardrobe and steel pipe wardrobe is good or bad, according to personal preferences to set, and that environmental protection seems to have grades, easy to crack
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
