Detailed Product Description: | IF Bend Features 6. Welding arc length intermediate pipe, welding ordinary steel to 2 ~ 4mm better, but when welding stainless steel to ~ 3mm better IF U-bend wholesale, long the protective effect is not good. 7 when the docking base, the bottom of the back to prevent oxidation of the weld, the need to implement the backside gas. 8 is well protected argon weld pool, and ease of welding operation, the center line of tungsten welding of the workpiece should be maintained 80 ~ 85 ° angle, the angle between the filler wire and the workpiece surface should be as small as possible, is generally about 0 °. 9 windproof and ventilation. Windy place, it should take steps to block network, and in the indoor ventilation should take appropriate measures. Large diameter elbow Description: Big Bend Model name suggests is a relatively large elbow. Big Bend is the use of sets of bending bending mold, no matter what kind of machinery and equipment, most of them use the elbow, the main purpose is to big bend oil, gas, infusion, etc., in aircraft and engine on More occupies a very important position. Precautions big bend: 1, big elbows bent tube under the action of external torque M in which the outer layer arm wall tensile stress and thinning, medial compressive stress. Thickening effect, force N1 and N2 so that the tube cross-section changes. Based on this factor, caused mainly due to the decline in the quality elbow RX and SX So, GBJ235-82, and the RX value and volume thinning various pressure levels outside of the case made it clear that the purpose is to control the RX the value SX, thereby ensuring the quality. 2, when the big elbow bend is produced outside material tension, pressure inside the location where the neutral axis and bending methods and different, while working at the top curved (compression and bending) from the neutral axis of the outer wall is about 1 / 3 IF Bend superior quality carbon steel, in the spin bend (curved back) work IF Bend steel manufacturer, the neutral axis is 2/3 from the outer wall. Therefore, the thin-walled pipe bend, bending method using a spin beneficial. 3, the accuracy of the big elbow bent tire also one of the factors affecting the quality of the elbow. When we made the turn tires, except when the Size control to a certain tolerance requirements, but also requires the user to select the appropriate bend when used in accordance with the bending diameter tires. IF Bend, welcome to Hebei million gold piping, U-IF Bend provided by Hebei billion in wholesale gold piping. Gold Pipe Manufacturing Co., Ltd. Hebei billion (www.yijinguanjian.com) in the insulation joints, insulating flange, flanges, elbows, head, tee, head, Stone, steel and other industries have a higher visibility, credibility Operating both quality service, welcome to inquire, or consult our "Business League call" it! |
