   Special shaped steel pipe Common processing methods

Here it is Special shaped steel pipe The most common process testing methods are as follows:

(1) continuous bending experiment: one end of the specimen is clamped. In order to test the ability of metal materials to resist continuous bending and display the information of its shortcomings, the experiment of 90 degree repeated reverse bending on the surface of cylindrical surface required to be semi warp is carried out;

(2) upsetting test: hammering or forging shall be carried out on the specimens with required specifications. testing Special shaped steel pipe An experiment of the ability to undertake the plastic deformation of upsetting and display information about its disadvantages under indoor temperature or thermal conditions. The forging experiment carried out at indoor temperature is called indoor temperature upsetting experiment, also known as cold upsetting experiment. The hot forging experiment is called hot upsetting experiment;

(3) tube rolling experiment: pressing the top center of the required shape into one end of the metal hose to make the wall thickness uniform to the required specification, and detect the working capacity of the wall thickness to bear the inner roll plastic deformation, and display the information about its shortcomings;

(4) tube hydraulic press experiment: the experiment in which tap water or liquid is required to fill the metal hose, bear the required working pressure within a certain period of time, detect the quality and compressive strength of the special-shaped steel pipe and display the information of its disadvantages;

(5) machinability: it refers to the working ability of steel to accept heat treatment after martensitization, or the change trend of martensite to austenite, which is indicated by the deep layer of hardened layer. The deep layer of hardened layer refers to the distance between surface layer and semi austenite layer. For the alloy tool steel, the main way to test the cutting performance is the heat treatment experiment of the alloy structural steel end required by the national industry standard;

(6) drilling process performance: the main characteristics of special-shaped steel pipe raw materials to be produced and processed with cutting tools. When drilling or cutting, it is very easy to achieve high surface machining accuracy, and special tools are not easy to wear, cutting is very easy to fall off, cutting speed is low, all these indicate that the metal composite material has good drilling performance;

(7) bending test: the test piece is bent to the required level with the bending center of required specification, and the working ability of metal materials to bear bending plastic deformation is detected and the information about its disadvantages is displayed. Generally, the bending center diameter, bending angle and surface layer at the bending point shall be required;

(8) tube bending test: bending the test piece to the required level in the grooved bending center, and testing the working capacity of the special-shaped steel pipe to bear the bending plastic deformation and displaying the information of its shortcomings;

(9) tube flattening experiment: the experiment to flatten the metal hose to the required specifications, test its plastic deformation working capacity and display information on its shortcomings;

(10) tube flaring experiment: an experiment in which the top center required to be smooth is pressed into one end of the metal hose, so that the diameter is evenly expanded to the required specification, and the working capacity of the axial expansion plastic deformation of the special-shaped steel pipe is detected and the information about its shortcomings is displayed.
