Description
Technical Field
[0001] The invention relates to the field of pipe straightening, and more particularly to a steel pipe straightening device. Background Art
[0002] Oil casing, also known as petroleum casing, is mainly used to support the well wall during the drilling process and after completion to ensure the normal operation of the entire oil well after the drilling process and completion. It is a pipeline connection and protection device for oil wells, and can also be used for water and gas injection in oil wells. Oil casing is usually made of steel pipes, which have the characteristics of high strength, corrosion resistance and high temperature resistance, and can withstand oil and gas extraction operations under high pressure and high temperature environments. During the production, processing and transportation of oil casing, bending or deformation will occur due to various reasons. If the oil casing is bent or deformed, it will affect its connection performance with other pipes or equipment, and even cause connection failure. For this reason, steel pipe straightening equipment is needed to straighten these bent or deformed oil casing, so as to improve the straightness and overall quality of the product.
[0003] The current straightening operation of oil casing mainly relies on the two rollers configured inside the straightening equipment to squeeze the outer wall of the pipe to achieve the straightening effect. However, in this operation process, the operator must manually hold the steel pipe and accurately insert one end of it between the upper and lower rollers inside the straightening equipment, and also apply a certain thrust to ensure that the steel pipe can be tightly clamped by the rollers.
