Common Causes of Gas Holes in Spiral Steel Pipe Welding

  One of the requirements of spiral steel pipe welding is to have compactness, so that accidents can not occur when using spiral steel pipe. In the production of  ASTM A53 Gr.B 1000mm Diamete Spiral Steel Pipe , some conditions will be encountered, such as gas holes. When the welded spiral steel pipe are manufactured, gas holes will appear in the welds. If there are gas holes in the welds when the welded spiral steel pipe are in use, it will affect the compactness of the welded spiral steel pipe and cause serious losses due to leakage of the pipes. In addition, when the welded spiral steel pipe is used, it will also cause corrosion because of the gas holes in the weld, which will reduce the service time of the welded pipe.   The common reasons for the occurrence of gas holes in the weld of spiral steel pipe .There is water in the flux, or some dirty things, etc. When spiral steel pipe is welded, these things will cause gas holes in the welded spiral steel pipe. When welding, sele...

How to Produce Boiler Pipe

  Boiler pipe is a kind of seamless pipe. The manufacturing method is the same as seamless boiler pipe, but there are strict requirements for steel grades used in manufacturing boiler pipe. According to the use temperature, it can be divided into general boiler tube and high pressure boiler pipe.   The mechanical properties of boiler pipes are an important index to ensure the ultimate service performance of steel, which depends on the chemical composition of steel and heat treatment system. In the  High Pressure Seamless Steel Boiler Pipe  standard, according to different application requirements, the tensile properties (tensile strength, yield strength or yield point, elongation), hardness and toughness indexes, as well as the high and low temperature properties required by users are specified.   1. Generally, the temperature of boiler pipe is below 350 C. Domestic pipes are mainly made of hot-rolled or cold-drawn carbon-bonded steel tubes No. 10 and No. 20.   2. High ...

Difference of Bearing Capacity of Spiral Steel Pipe

      The bearing capacity of spiral steel pipe is related to two points. One is the mechanical properties of steel, which is related to yield point, tensile strength, elongation and impact toughness, and the other is related to the geometric characteristics of its section. Generally, circular spiral steel pipe has the strongest resistance to local buckling, so it is the best component to withstand radial internal pressure and external pressure.   Under the same steel size, area and support conditions, the eccentric compressive bearing capacity of  API 5L X52 Spiral Steel Pipe  is stronger than that of circular and spiral steel pipe, while the axial compressive bearing capacity of square and rectangular spiral steel pipe is the strongest, but the local buckling resistance of square and rectangular spiral in the compressive zone is not as good as that of spiral steel pipe. Compared with spiral steel pipe, seamless steel pipe has complex production process, hig...

Overall trend of oil pipeline price

        1. This week's social inventory of oil pipe continued to decline and maintain a low level, without the conditions and momentum for a sustained decline, neutral;   2. After the substantial adjustment of the spot price of oil pipe in November, the stage risk has been basically released. At the beginning of this month, the steel price needs rebounding repair, which is beneficial.   3. At present, there are some phenomena in some parts of the country, such as the shortage of goods and specifications, which have a supporting effect on prices and have more advantages.   4. At present, some steel mills have maintenance plans, and the supply is indeed decreasing. Prices do not have the conditions for a sustained sharp drop, so they are more profitable.   5. At the beginning of the month, the pressure of oil pipe on the market's capital will be eased and the market will be more profitable.   6. Influenced by the low temperature in winter, demand will furthe...
