Shandong Liaocheng Polygram Pipe Manufacturing Co., Ltd. invested more than 800 million imported equipment can produce their own small implements seamless steel pipe, produce specifications for ￠ 4- ￠ 108mm ￠ 1- ￠ 20mm pipe wall thickness, while the introduction of two sets of thermal expansion equipment to produce specifications for ￠ 273- ￠ 720mm wall thickness ￠ 6- ￠ 50mm pipe. You can be processed to build the pipe, rectangular pipe, centrifugal casting seamless steel pipe, large diameter straight seam pipe (polished welds may be testing). In order to better serve the old and new customers, the company offered a home delivery service, and a car, hand pick customers to negotiate business. Steel pipe plant have long been using centrifugal casting, investment casting and sand casting and other processes. Provide a variety of machinery, petroleum, chemical, textile, metallurgy, food industry P carbon steel, stainless steel, alloy steel and other components. Main products: 1, using horizontal centrifugal casting mold process to produce less than the outer diameter of φ1000mm, bore φ190mm above, within the length of 7000mm, wall thickness less than 120mm, single weight 5.9 tons of various pressure tanks, and Kun tube, pipe, the annual production capacity of 1,200 tons. Services: packet loss came no goods, the goods are not satisfied with the loading, after finishing the formalities and then pay the company always adhere to market-oriented, the growing scale enterprises to enhance their core competitiveness, the North Sea in the shortest time trying precision steel tubes, create the best brand of seamless steel tubes, to provide the most satisfactory service. In the pipe / seamless steel pipe increasingly competitive market today, the company good governance precision steel tubes, excel through, seamless steel pipe industry to revitalize the national and local economies and endless struggle. Liaocheng in Shandong Steel Pipe Manufacturing Co., Polygram Main products: electricity, petroleum, chemical, container, boiler industry with American Standard pipe, seamless pipe, line pipe, casing, spiral, straight seam pipe, high pressure alloy pipe high-pressure boiler tubes, high-pressure boiler seamless steel tubes threaded, low pressure boiler tubes, high pressure seamless diesel, fertilizer equipment, high pressure seamless pipe, petroleum cracking high-pressure seamless pipe, carbon steel and carbon-manganese steel vessel seamless pipe, hydraulic prop car sleeve pipe, transmission fluid line pipe, structural pipe, coal hydraulic prop tube, cold-rolled precision light tube, precision light pipe looks smooth, uniform thickness, high precision. A hydraulic test: steel hydraulic test should be carried out gradually, with no penetration. Formula formula: P = 2SR / DP- test pressure (Mpa) S --- nominal pipe wall thickness (mm) D- nominal diameter steel pipe (mm) R- allowable stress two, flattening test: diameter greater than 22mm, and a wall thickness less than 10mm of steel flattening test, the formula is: H = (1 + a) S / a + S / DH- steel plane distance S --- D --- nominal wall thickness of steel pipe nominal diameter a- unit length deformation coefficient of 0.08 visitors precision steel tubes, when S / D greater than or equal to 0.07 1.25, flattening test shall not have cracks and cracks. 4, bending test: 22mm outside diameter less than equal to the pipe shall be tested by bending the bending angle of 90 degrees, the apex radius of 6 times the pipe diameter, the bend may not cracks and cracks, cracks.
