ASTM A106 Seamless Steel Tube is a seamless steel tube that complies with the American ASTM A106/ASME SA106 standard. ASTM A106 Seamless Steel Tube is available in three grades: A106 Grade A Seamless Steel Tube, A106 Grade B (Gr.B) Seamless Steel Tube, and A106 Grade C Seamless Steel Tube. A106 Grade A Seamless Steel Tube is preferred for cold roll forming.
ASTM A192 Boiler Tube is a seamless carbon steel boiler tube for ASTM A192/ASME SA192 high-pressure equipment. ASTM A192 Boiler Tubes are mainly used in high-pressure equipment such as high-pressure boilers and superheaters to transport high-temperature and high-pressure steam or hot water. They play an important role in high-pressure steam systems in the power, petrochemical and other industries, and are one of the key components to ensure the energy conversion and transmission efficiency in the production process of these industries.
ASTM A210 Boiler Tube is a seamless medium carbon steel tube for ASTM A210/ASME SA210 boilers and superheaters. ASTM A210/ASME SA210 standard applies to seamless medium carbon steel tubes for boilers and superheaters. ASTM A210 Boiler Tubes include seamless steel tubes with small wall thickness for boiler tubes, boiler flue tubes, safety ends, domes and support tubes, and superheater tubes. The production methods of steel tubes under ASTM A210/ASME SA210 standards include hot rolling, cold drawing and hot expansion. The delivery state is usually hot rolled or heat treated. These production methods ensure the quality and performance stability of the steel tubes during the manufacturing process.
ASTM A213 Boiler Tube is a special steel pipe for high-temperature and high-pressure steam pipelines, also known as boiler tubes. It is usually made of carbon steel or alloy steel, with excellent high temperature resistance, corrosion resistance and pressure resistance, and is widely used in petroleum, chemical, electric power, construction and other fields.

Boiler steel pipes are critical pressure-bearing components used in boilers and thermal equipment for conveying high-temperature, high-pressure media. Their materials must possess good high-temperature strength, oxidation resistance, and structural stability.
CK45 Honed Steel Tube is a precision steel tube widely used in industry.
CK45 Honed Steel Tube uses 45# steel as its base material, a carbon structural steel with a moderate carbon content that balances strength and toughness.
CK45 Honed Steel Tube undergoes a honing process to achieve a high surface finish and dimensional accuracy on the inner wall of the tube. The honing process uses tools such as a grinding stone to micro-cut the inner wall of the tube, removing machining marks left by previous processes and creating a uniform cross-weave pattern that facilitates lubricant storage and distribution.
DIN2391 ST52 Honed Tube and Pipes are high-precision cold-drawn seamless steel tubes widely used in hydraulic systems, construction machinery, and automotive precision components. They conform to DIN2391-1 or GB3639-83 standards. Made primarily of carbon steel, DIN2391 ST52 Honed Tube and Pipes undergo cold drawing/cold rolling, pickling, and phosphating processes. They exhibit high precision (inner diameter accuracy up to ±0.02-0.05mm) and low surface roughness, and are capable of withstanding high pressures and resisting deformation.
EN 10305-1 E355 Hydraulic Cylinder Honed Steel Pipe is processed through cold drawing and hot rolling, achieving high precision and strength, making it suitable for mechanical structural components and hydraulic equipment. Hydraulic Cylinder Honed Steel Pipe is available in a wide range of specifications, with inner diameters ranging from 20mm to 400mm and wall thicknesses ranging from 3mm to 50mm.
Our factory produces and sells various specifications and models of honed steel tube, including precision honed steel tubing, Hydraulic Cylinder Steel Pipe, Hydraulic Honing Steel Pipe, large-diameter honed steel tubes, and small-diameter honed steel pipe.
Our factory has six honed steel tube production lines capable of processing 12-1100mm honed steel tube (for model aircraft and cylinder tubes). The honed steel tubes (for model aircraft and cylinder tubes) produced by our factory typically achieve a roughness of Ra ≤ 0.08μm, correct roundness, and ovality ≤ 0.01mm. This improves surface hardness, eliminates stress-induced deformation, and increases hardness to HV ≥ 4°. A residual stress layer is formed after processing, increasing fatigue strength by 30%, improving fit quality, reducing wear, and extending component life.
Hydraulic cylinder steel pipe, also known as honing pipe, is a core component for transmitting high-pressure fluids in hydraulic systems. It is a cold-drawn or cold-rolled precision seamless steel pipe. Hydraulic cylinder steel pipe is primarily made of carbon steel (such as ST35 and ST45), alloy steel, and 304L stainless steel. It is widely used in hydraulic cylinders, pneumatic cylinders, construction machinery, and automotive precision components.
Hydraulic Honing Steel Pipe is a precision pipe manufactured through a honing process. Its interior surface undergoes a special treatment, resulting in exceptionally high smoothness and dimensional accuracy. Honing is a combined grinding and polishing process that effectively removes microscopic irregularities on the pipe’s interior surface, resulting in a mirror-like finish. Hydraulic Honing Steel Pipe is typically made from high-quality alloy steel or stainless steel and undergoes multiple processing steps to meet the needs of diverse industrial applications.
Schedule 40 Steel Pipe is a commonly used wall thickness grade in American Standard piping systems. It has clear pressure standards and application specifications and is widely used in industries such as the petroleum and chemical industries. SCH40 Steel Pipe is available in welded, seamless, and galvanized versions, depending on the production standards and intended use.
