Steel pipe bending is a commonly used processing method for some steel pipe users. Today, I will introduce a simple method for bending steel pipes.
The specific methods are as follows:
1. Before bending, the steel pipe to be bent should be filled with sand (just fill the bend), and then both ends should be tightly blocked with cotton thread or waste newspaper to avoid collapse of the steel pipe during bending. The denser the sand is poured, the smoother the bends it bends.
2. Clamp or press the steel pipe, and use a thick steel rod to insert it into the steel pipe as a lever for bending.
3. If you want the bent part to have a certain R-arc, you should find a circle with the same R-arc as the mold.
Method for bending galvanized steel pipes:
To use a hydraulic pipe bending machine for bending, the length of the elbow should be considered before bending. Galvanized steel pipes must be of national standard, otherwise they can easily collapse.
The galvanized steel pipes produced by Yuantai Derun are divided into pre galvanized steel pipes and hot-dip galvanized steel pipes. Pre galvanized steel pipes may be replaced by zinc aluminum magnesium coated steel pipes in the future, which are also advocated by the state for use. Currently, internationally developed structural steel pipe manufacturers are beginning to develop new types of pipes and are gradually putting them into operation.
The method of manually bending circular pipes involves the following steps:
1、 Before bending the steel pipe, we need to prepare some sand and two plugs. First, use a plug to seal one end of the pipe, then fill the steel pipe with fine sand, and then use the plug to seal the other end of the steel pipe.
2、 Before bending, burn the area where the pipe is to be bent on the gas stove for a while to reduce its hardness and make it softer, making it easier to bend. When burning, rotate it to ensure that the pipe burns soft all round
3、 Prepare the roller according to the shape and size of the steel pipe to be bent, fix the wheel on the cutting board, hold one end of the steel pipe with one hand and the other end with the other hand. The part to be bent should lean against the roller, and gently bend with force to easily bend into the arc we need.
