The development of steel tubular towers

Compared with foreign countries, the steel structure of transmission tower in China has a single variety, low strength value and little choice. When the tower load is large, only the composite section can be used to make up the shortage of material strength, and the workload and investment of design and processing are increased. The United States “transmission Tower Design Guide” in a total recommended 10 kinds of material standards for designers to choose, the yield strength of high-strength steel reached 448MPa.   ERW galvanized steel pipe for steel structral  Product name ISO65 ERW galvanized welded steel pipe Technique Longitudinal Electronic […]

U.S. Measurement Pipe Dimensions

1.Place your pipe on a flat surface. 2.Measure the outside diameter of the pipe using a micrometer or caliper. Write down that measurement. 3.Measure one inch from the end of the pipe with a tape measure or caliper and make a small mark with a permanent marker. 4.Count the number of threads in that inch. Write down that number. Compare that measurement with a pipe measurement chart. 5.Place your pipe on a flat surface. 6.Measure the outside diameter of that pipe with a micrometer or caliper and write down that measurement. 7.Measure the distance between any two adjacent threads on […]

Development Tendency of Seamless Steel Pipes in 2017

The situation of domestic steel pipe was negative in 2016. Even has the positive currency policy, the funds was still a headache for steel pipe factories. What’s worse, the slowdown economic growth and frequently blocked export environment deteriorated the harsh situation of domestic market. In 2016, the market will be mingled hope and fear. The hope is due to the negative situation in 2015, the market will accelerate the adjustment of production structure and form a new pattern for steel pipe; besides, the policy will also promote the demands for pipes. The fear is that, the steel pipe industry has […]

Large diameter welded pipe cooling way

Cooling in cooling bed has a chain of cooling bed, worm cooling conveyor and rack-type cooling bed. According to the performance requirements of large diameter welded pipe, can use different ways to cool. Forced cooling. Large diameter welded pipe for metal has certain organization and physical properties, should take the control of cooling speed. Such as bearing tube, in order to prevent the precipitation of carbide network, cooling rate no less than 50-70 – c/min, and take the way of ventilation or water mist forced cooling. Natural cooling. There is no special performance requirements of large diameter welded pipe, can […]

2017: A Promising Year for China’s Steel

2017 will be a promising year for China’s steel, mainly at: First of all, supply and demand will keep in balance in the next year, but the species differentiation, exports declined. In fact, cold, hot plate growth rate of more than 5%, but building materials, seamless tube have negative growth, the differentiation of the species has been very clear. Currently steel springboard, decoiled steel sheet, hot-rolled plate and other product prices raise steadily. Secondly, the cost will rise next year, mine and coke will greatly enhance, the same to steel, and will keep raise. The third is a qualitative changed […]

Distinguish defective square tube

1, Defective square tube because the processing is not in place, the appearance will be a lot of glitches, and these burrs will be very simple scratches the pipe surface, so the first identification method came out, there are many scratches on the exterior of the Is the quality of the poor. 2, Defective side tube manufacturers in order to reach a large negative public service will increase the amount of product processing when the reduction, and this will result in products of fine and low cross-ribs, so if you find such a situation, then the best side do not […]
