What is a precision steel tube

What is a precision steel tube? Precision bright tube (precision steel tube) is a kind of ordinary seamless steel tube (or de-diameterized welded steel tube) processed by fine drawing or cold rolling to a high precision steel tube material. Since there is no oxidation layer on the inner and outer wall of precision bright tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening without cracks, etc., it is mainly used to produce products of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless tubes or welded tubes. […]

Processability analysis of parts and selection of blanks

Parts of the process analysis 1. Check the integrity of the parts diagram: review the size of the parts diagram is complete. The structure is expressed clearly. 2. Analysis of technical requirements are reasonable. (1) The dimensional accuracy of the machined surface. (2) The main processing surface shape accuracy. (3) The mutual position accuracy of the main processing surface. (4) Surface quality requirements. (5) Heat treatment requirements. The dimensional tolerances. form tolerances and surface roughness of the parts marked. should be based on the function of the parts economically and reasonably decided. Too high requirements will increase the difficulty of […]

Machining process of flange parts

With the continuous development of science and technology, the quality and productivity of mechanical products have been increasingly demanding. Automation of machining process is one of the most important measures to achieve the above requirements. It can not only improve the quality of products, increase production efficiency and reduce production costs, but also greatly reduce the labor intensity of workers.  In recent years, due to the increasingly fierce competition in the market, in order to survive and develop in the competition, the production and processing enterprises not only to improve product quality, but also must continue to improve and shorten […]

How to make high quality copper elbow

How to make high quality copper elbow? This article presents several methods of positioning copper elbows with examples that are relatively simple and can quickly produce high-quality, dimensionally accurate copper elbows from copper tubing without creasing or ovaling. When making copper elbows, bending springs are used to support the copper pipe wall. The bent spring is suitable for all copper pipe diameters from 10 to 22 mm in Table X and Table Y of BS2871 standard, and the maximum recommended copper pipe diameter for using the bent spring is 22 mm. With careful handling, semi-rigid copper tubes up to 22mm […]

What is a steel structure

What is a steel structure? Steel structure refers to a structural form that can bear and transfer loads by using steel plates and hot-tied, cold-formed or welded sections connected by connectors. Steel structure system has the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution, etc. Compared with reinforced concrete structure, it has the unique advantage of developing in three aspects of “high, large and light”. In the field of construction, steel structures are widely and reasonably used. Steel structures are widely used in various engineering constructions, […]

What are high-strength bolts

What are high-strength bolts? High-strength bolts made of high-strength steel, or bolts that require a large preload, are called high-strength bolts. High-strength bolts are mostly used for bridges, rails, and connections for high-pressure and ultra-high-pressure equipment. The fracture of these bolts is mostly brittle. High-strength bolts used in ultra-high-pressure equipment require a large pre-stress to ensure the sealing of the container. Several concepts about high-strength bolts: The performance level of bolts above grade 8.8 is called high-strength bolts according to the regulations. The current national standard is only listed to M39, for large size specifications, especially the length of high-strength […]

Causes and countermeasures of missed detection and misjudgment in penetrant de……

Causes and consequences of missed detection and misjudgment What is penetration detection? Penetration detection is mainly composed of 9 major links including pre-cleaning. drying. infiltration. pre-washing. emulsification. washing. drying. imaging and inspection. among which the four links of pre-cleaning. emulsification. washing and inspection are the most important. Improper operation of these links may cause errors in the final test results. The surface condition of parts is not good or clean badly A. paint layer. anodized layer or oxide skin If the paint layer. anodized layer or oxide skin on the surface of the parts is not removed clean. and the […]

Selection of common pipe fittings for dairy production lines

Dairy production line is a kind of food production line, modern dairy/beverage/wine/pharmaceutical industry is actually a branch of the chemical industry, and the production line has a great commonality. Chemical industry is a “sex change” process, different from the “shape change” of machine processing, the equipment is relatively simple, and all the production lines are “tubes, pipes and tanks”, i.e. for reaction (tanks) and process transport (pipe), which is also the main work of the dairy engineering enterprises. Used for conveying (pump), online processing (separation, homogenization, sterilization), providing reaction conditions (heat exchange) and packaging machines, the actual does not belong […]

What are groove pipe fittings

What are groove pipe fittings Groove fittings are a new type of steel pipe connection fittings, also called clamp connections, with many advantages. Categories of groove fittings Groove fittings include two major categories of products. ① Fittings that play the role of connecting and sealing are rigid joints, flexible joints, mechanical tees and grooved flanges. ② The fittings that play the role of connecting transition are elbow, tee, cross, reducer, blind flange, etc. The role of the connection sealing groove connection fittings are mainly composed of three parts: sealing rubber ring, clamps and locking bolts. The inner rubber seal ring […]

What is pipeline transportation

What is pipeline transportation Pipeline transportation is a mode of transportation of liquid and gaseous materials over long distances using pipelines as a means of transportation, a mode of transportation of oil, coal and chemical products exclusively from production to market, a special component of trunk transportation in the unified transport network. Sometimes, pneumatic tubes can do similar work, transporting solid compartments with compressed gas, while the cargo is contained inside. Transporting petroleum products by pipeline is more expensive than water transport, but still cheaper than rail transport. Most pipelines are used by their owners to transport their own products. […]
