How many cutting methods have you got for stainless steel tubes?

 1. Grinding wheel cutting: This is the more commonly used method at present, that is, cutting with a grinder, but there will be more burrs on the pipe port after cutting out. If a fully automatic stainless steel pipe end C burr removal machine can be used in conjunction with the cost cheaper. 

2. Wire cutting: It is the use of wire cutting and fast-moving wire, so that the cutting can meet the requirements of the quality of the incision, but it should be noted that the color of the pipe end will change after cutting, and the grinding and polishing treatment method is required to achieve the desired effect.

 

3. Metal circular saw cutting: this cut is better, and can achieve several simultaneous cutting, but the chips easily stick to the props, so you need to be careful when buying saw blades.

 

4. Rolling blade chipless pipe cutting machine: smooth cut without sawtooth, suitable for small and medium-sized enterprises. The disadvantage is that auxiliary devices need to be added, otherwise, when cutting thin-walled stainless steel pipes, tearing easily occurs, resulting in severe deformation of the nozzle.

History of Galvanized Steel Pipe

 The process of galvanization was first discussed by scientists in the 1770s, nearly 60 years before it was finally introduced in the 1830s. French engineer Stanislaus Tranquille Modeste Sorel took out the first patent for the process in 1937, and began manufacturing it soon after. By the 1850s, Europe was producing galvanized steel out of manufacturing plants located around the continent. The United States followed shortly thereafter, opening its first plant in the 1870s.

 To create galvanized steel pipe,steel materials are placed into a molten bath of zinc. This process is also called hot dip galvanization. The two metals are chemically bound to one another in this process, and will therefore never separate, resulting in a more resistant and longer lasting version of steel.

How to reduce the damage of cold working to stainless steel tube?

 1. The stainless steel pipe standards in most countries, especially the European Union-stainless steel pipe standards, stipulate that all stainless steel seamless steel pipes must be supplied in a solid solution or annealed state to eliminate performance damage caused by cold processing and welding.

2. Three key parameters should be paid attention to during solution treatment: heating temperature, rapid cooling method and high temperature residence time. Excessively high solution treatment temperature or residence time is detrimental to the corrosion resistance of the material. Determine whether the solid solution is in place, and measure the hardness. Flaring, crimping, flattening, and tensile data can be determined. The hardness measurement is the easiest.

3. Due to solid solution or annealing due to high temperature heating and pickling treatment, the manufacturing cost and production cycle are significantly increased. In addition, there are waste gas and waste water emissions such as acid mist. Some companies omit this process and use this product, which is easy to produce after use. Production and personal accidents.

4. For some products or application conditions where it may be difficult to implement solution or annealing, controlling the degree of cold work [cold plus I deformation amount and locally performing low-temperature stress relief annealing are practical methods to reduce harmful effects.

How to improve the durability of spiral steel pipes

 Spiral steel pipes require exterior treatment to add durability.

1.Using solvent and emulsion to clean the surface of the anti-corrosive spiral tube. This can remove the organic material on the surface of the spiral tube, but it cannot remove the surface rust, scale, solder, etc. Therefore, cleaning can only be used as an auxiliary means.

2.Using wire brushes, sandpaper, etc. to polish the surface of the anti-corrosion spiral tube, which can remove loose oxide scale, rust, welding slag, etc.

3.Pipeline anticorrosion is selected by chemical pickling, which can remove scale, rust and old coatings, and can achieve a certain degree of cleanliness and roughness.

4.The high-speed motor drives the spray (projection) blades to rotate at high speed, so that abrasives such as steel grit, steel shots, wire segments, and minerals can be sprayed (projected) on the surface of anti-corrosive steel under the effect of centrifugal force, which can not only completely remove Rust, oxides and dirt, and the anti-corrosion steel pipe can achieve the required uniform roughness under the effect of the strong impact and friction of the abrasive.

Features of L245NB line pipe

 L245NB pipeline pipe is widely used in petroleum and natural gas engineering. Our company has passed the certification of API ISO CE BV CCS and other authoritative organizations. Products are exported to dozens of countries and regions, and have become the preferred fixed supplier for many engineering companies.

 L245NB pipeline standard: GB / 8163-2008, American standard ASTM A53 / A106, German standard DIN 1629 DIN2448 DIN17175, European standard EN10204, Japanese standard JIS G3462, material: API 5L GRB X42 X46 X52 X56 X60.

 

The structure obtained by high temperature tempering of L245NB line pipe is tempered sorbite. The heat treatment combined with quenching and high temperature tempering is conventionally called quenching and tempering, and its purpose is to obtain comprehensive mechanical properties with good strength, hardness, plasticity and toughness. Therefore, L245NB line pipe is widely used in automotive, GB / T9711.1 pipeline steel pipe, machine tools and other important structural parts, such as connecting rods, bolts, gears and shafts. The hardness after tempering is generally HB200-330.
