Galvanized q355b square pipe for low pressure fluid transmission, Standard No.: gbt3092-2008. The representative material is the same as above. It is mainly used to transport low pressure fluids such as water, gas air, oil and heating hot water or steam. The surface of square pipe adopts hot galvanizing or cold galvanizing process.

Square pipe is the name of square pipe, that is, steel pipe with equal side length. It is made of rolled strip steel after process treatment. Generally, the strip steel is unpacked, leveled, crimped and welded to form a round pipe, then rolled into a square pipe from the round pipe, and then cut into the required length. Usually 50 pieces per bag.

Scottsdale.Generally, rust and old coatings. Professional square tubes which can remove oxide scale, rectangular tubes, seamless square tubes galvanized square tubes and galvanized tubes are safe, environmentally friendly and economical! The products are exported to foreign countries and are deeply trusted. Sometimes they can be used as reprocessing after sand blasting and rust removal. Although chemical cleaning can make the surface reach a certain cleanliness and roughness, its anchor lines are shallow and easy to pollute the environment.

The square tube shall be painted correctly. Professional square tube, square rectangular tube, seamless square tube,ScottsdaleGanzhou galvanized pipe, galvanized square tube and galvanized square tube have stable, safe and reliable performance and can be maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. Otherwise, the square tube will be corroded. The correct paint shall also be selected during painting, so as to ensure that the square tube can be used more firmly, So as to ensure that the square tube will be better and better in future use. The square tube is widely used in the soul. Each kind of square tube has different functions for the other tube. We choose the right way and different square tubes, which can increase the performance of the square tube and be applied to different fields. Let me briefly introduce the lower tube.

.Strength refers to the function that the square tube data is destroyed under static load (appropriate amount of plastic deformation or fracture), because the action form of load includes tension, compression, meandering shear and so on, because the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. There is often a definite connection between various strengths. In normal use, tensile strength is often used as the fundamental strength gauge.

At present, there is still a lack of research on surface adhesion, there is no systematic and perfect theory to guide the preparation of anti adhesion inner surface of pipeline, and there is a lack of operable and low-cost inner surface preparation technology of square pipe. In terms of solid surface adhesion mechanism, based on the solid-liquid interface adhesion work theory and smooth solid surface model, this paper analyzes the spreading process on machined rough surface, studies the dynamic movement characteristics of solid-liquid vapor phase line, directly analyzes the adhesion process, and establishes a line spreading model based on small system energy, It provides theoretical guidance for the preparation of anti adhesion surface of pipeline.

The square tube adopts the electric contact pressure gauge to press down the pressure of the oil cylinder on both sides of the conveyor to ensure the smooth transportation of the strip steel.

The raw material for rolling square tube is round tube blank. For a long time,ScottsdaleThick walled square tube, square tube, rectangular tube, seamless square tube, galvanized square tube and galvanized tube have complete products, excellent quality and favorable price. The round tube embryo shall be cut and processed by cutting machine, and the blank with a growth of about 1m shall be brought to the furnace for heating. The billet is sent to the furnace for heating at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature in the furnace is the key problem. After the round tube billet is discharged from the furnace, it should be pierced through the pressure piercer. Generally, the more common piercer is the conical roll piercer. This piercer has high production efficiency, good product quality, large perforation expansion and can wear a variety of steel grades.

When the vehicle is replaced with seamless square tube blank, the material is too soft to affect the requirements, so as to ensure the quality of parts and avoid wrinkles.

Application: it is widely used in machinery, construction, metallurgy, agricultural vehicles, automobiles, railways, highway guardrails, container frames, square tubes, raw materials, i.e. strip coils, and the cutting line shall be at right angles to the axis of the square tube. Excessive force is the reason for cutting the square tube into flat or oval, so the square tube should be cut with appropriate force.

After isothermal quenching qq355b square tube will have excellent rolling fatigue characteristics and corrosion resistance. Wear resistance, fracture toughness, impact toughness and bending strength. Therefore, in the subsequent production and application, qq355b square tube will be used as the material of rolling mill flap ball screw. The qq355b square tube of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment, and its application range is expected to be improved and expanded.

After the square pipe is produced the surface treatment is generally carried out, that is, the scale, rust, dirt and attachments on the surface of the square pipe are removed. Those that cannot be treated by physical treatment should be treated by chemical treatment.

Work courses.The modification of Ca, rare earth and other trace elements on inclusions changes the structure, morphology and physical properties of inclusions in steel, spheroidize and refine inclusions in steel, so as to improve the mechanical properties of square tubes.

Forging square tube: a kind of pressure processing in which the reciprocating impact force of the forging hammer or the pressure of the press changes the blank into the shape and size we need. It is generally divided into forging and die forging. It is often used to produce large-scale materials and materials with large square tube size.

After the square tube is cut into a single square tube, the head and root of each batch of square tube shall be subject to strict first inspection. The mechanical properties, chemical composition, surface quality of square tube and NDT shall be carried out to ensure that the pipe making process is qualified before it can be officially put into production.

Scottsdale.Be sure to select special for square pipe cutting.

After the square pipes are stacked and stored,ScottsdaleDN350 galvanized pipe, the pipe end protector shall be removed to avoid moisture gathering on the surface of the pipe end protector and the square pipe, which is difficult to volatilize.

Large diameter welded square pipe for low pressure fluid transmission, Standard No.: gbt14980-1994. Representative material: grade q235ab. It is mainly used to transport low-pressure fluids such as water, sewage, gas, air and heating steam.
