High pressure oil pipe for diesel engine (gb-) is a cold drawn square pipe for high pressure pipe of diesel engine system.Classification of square tube steel is iron carbon alloy with carbon content of square tube between .% - %. In order to ensure its toughness and plasticity, the carbon content generally does not exceed %. In addition to iron and carbon, manganese, phosphorus,GuazarPrice of galvanized pipe, etc. There are various classifications of steel and square tubes, mainly including the following: square tubes are classified into ordinary steel according to quality (P & le; .%, S & le; .%)Guazar,Stainless steel qb square pipe for mechanical structure, Standard No.: gbt-. Representative material Cr cr crni CrNi crninb, etc. It is mainly used for machinery, automobile, furniture, hotel and restaurant decoration and other mechanical parts and structural parts.When the vehicle is replaced with seamless square tube blank, the material is too soft to affect the requirements,GuazarGalvanized square pipe, so as to ensure the quality of parts and avoid wrinkles.Handan City,Large diameter qb square tube production standard classification square tube is divided according to production standard: national standard square tube, Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube and non-standard square tube. special shaped square pipe is the general name of square pipes with other cross-section shapes except circular pipe. According to the different cross-section shape and size of steel pipe, it can be divided into special-shaped square pipe with equal wall thickness (code D), special-shaped square pipe with unequal wall thickness (code BD) and special-shaped seamless steel pipe with variable diameter (code D) These special-shaped large-diameter qb square tubes are widely used in various structural parts, tools and mechanical parts. Compared with circular tubes, special-shaped tubes generally have large moment of inertia and section modulus, and have large bending and torsion resistance, which can greatly reduce the structural weight and save steel. Square tubes are an indispensable part of construction workDue to the increase of square tube production, there are more and more fake and shoddy square tubes in the market. How to distinguish the fake and shoddy square tubes? Let me teach you some points to distinguish the fake and shoddy square tubes.

Stage ( & mdash; )How about the tensile strength of square pipe: square pipe has good tensile strength, tensile strength and sufficient toughness which makes square pipe stand out in the field of steel pipe. The square tube has great advantages in high temperature,GuazarSquare galvanized pipe, and the stress (& sigma;) obtained from the original cross-sectional area (so) of the sample is called tensile strength (& sigma; b) high pressure and even high strength environment. What are its characteristics? We analyze it one by one: tensile strength (& sigma; b) the strong force (FB) borne by the sample during tensile breaking, and the unit is nmm (MPA).Hundreds of degrees Celsius, which can save energy.Standard requirementsThe advantage of empty bending is that it can bend the side length when the real bending cannot be carried out, such as synchronous bending and finishing of the upper side and side of qb square tube. Empty bending can also bend the inner corner of r.t without breaking the tube wall.Precision pipe is a seamless pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision seamless mechanical structure or hydraulic equipment can greatly save machining hours, improve material rate and improve product quality. Seamless pipe can be divided into hot rolled pipe and cold rolled pipe according to different productionFunctional index analysis of qb square tube - commonly used are Brinell angle (HB), Rockwell angle (HRC) and Vickers angle (HV) of qb square tube. Angle is a gauge needle to weigh the soft and hard level of metal data. The angle method is rarely used to determine the internal angle in the current life. It uses the metal data surface tested under the fixed load of the indenter with a certain number and shape to determine its angle value according to the level of the object.

There are many ways of ignition, such as arc, electric spark, flame, strong current, high-temperature furnace, electron beam, laser, high-temperature radiation, microwave, chemical furnace, etc.Market trend,Ferroalloy is an alloy composed of iron and silicon, manganese, chromium, titanium and other elements. Ferroalloy is the raw material for steelmaking. It is used as deoxidizer and alloy element additive for steel in square tube steelmaking.The difference between qb square tube and QA is that there are fewer impurities s and P and better low-temperature impact performance. From the welding point of view, when the impurity elements in the base metal are less, it is good for welding hot crack.Stainless steel square tube for fluid transportation (gbt-) is a hot-rolled (extruded, expanded) and cold drawn (rolled) square tube made of stainless steel for fluid transportation.Guazar,There are many processing technologies for square tubes. I won't introduce the specific processing technology here. We only know about the processing technology of each other's tubes. We may have insufficient understanding of its heating technology. Next, I'll give you a detailed introduction to the heating technology of the lower tubes.It is the process of drawing the die hole of the rolled metal blank (shape, pipe, etc.) into a section to reduce the length and increase. It is mostly used for cold processing.Superior square tubular steel (both P and s ≤ .%)
