201 thick walled stainless steel pipe refers to stainless steel pipes with a wall thickness to outer diameter ratio greater than 6%. Thick walled stainless steel pipes are divided into square pipes, round pipes, and rectangular pipes according to their appearance. Divided by caliber: small-diameter thick walled stainless steel pipes and large-diameter thick walled stainless steel pipes. Divided by purpose: thick walled stainless steel seamless pipe and thick walled stainless steel welded pipe. The production methods of thick walled stainless steel seamless pipes are divided into drawn pipes, rolled pipes, and extruded pipes. Generally, drawn pipes are used for medium and low-pressure pipelines.

201 thick walled stainless steel pipe products include: thick walled stainless steel seamless pipe, thick walled stainless steel welded pipe, thick walled stainless steel bright pipe, and thick walled stainless steel precision pipe. Characteristics: 1. Cold rolled products have good glossiness and beautiful appearance; 2. Excellent corrosion resistance; 3. Excellent high-temperature strength; 4. Excellent work hardening properties (weak magnetism after processing) 5. Non magnetic in solid solution state; 6. Compared to other stainless steel pipes, the price is relatively low. Scope of application: Pipeline, heat exchanger, food industry, chemical industry, clock industry, etc.

Thick walled stainless steel seamless pipe is a circular, square, or rectangular steel material with a hollow cross-section and no seams around it. Stainless steel seamless pipe is made by piercing steel ingots or solid billets into rough tubes, and then hot rolling, cold rolling or cold drawing them. Stainless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids. Compared with solid steel such as round steel, steel pipes are lighter in weight and have the same bending and torsional strength. They are an economical cross-section steel widely used in the manufacture of structural and mechanical parts, such as oil drill rods, automobile transmission shafts, bicycle frames, and steel scaffolding used in construction.

201 thick walled stainless steel pipe is a type of stainless steel pipe.

Stainless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold drawn pipes, extruded pipes, etc. according to different production methods. Hot rolled seamless pipes are generally produced on automatic pipe rolling units. The solid tube blank is inspected and surface defects are removed to cut into the required length. It is centered on the end face of the tube blank at the perforation end and then sent to a heating furnace for heating. It is perforated on a perforating machine while continuously rotating and advancing. Under the action of the rolling mill and the top, a cavity called a capillary tube is gradually formed inside the tube blank. It is then sent to an automatic tube rolling machine for further rolling. Finally, the wall thickness of the whole machine is uniformly adjusted, and the diameter is determined by a sizing (reducing) machine to meet the specification requirements. The use of a continuous tube rolling mill to produce hot-rolled seamless steel pipes is an advanced method. If you want to obtain seamless pipes with smaller size and better quality, you must use cold rolling and cold drawing or a combination of both methods. Cold rolling is usually carried out on a two roll rolling mill, and the steel pipe is in a variable cross-section circular hole groove Rolling in a circular hole formed by a stationary conical top, Cold drawing is usually carried out on a single chain or double chain cold drawing machine using the extrusion method. The heated tube blank is placed in a closed extrusion cylinder, and the perforation rod and extrusion rod move together to extrude the extruded part from a smaller die hole. This method can produce steel pipes with smaller diameters.

Specification for 201 thick walled stainless steel pipe

201 thick walled stainless steel pipe general specifications: Those with a wall thickness of (3mm) or more are commonly referred to as thick walled stainless steel pipes because their wall thickness is relatively thick.
