DIN2391 CK45 cold rolled steel pipes from Yantai Xinpeng Steel Pipe Co., Ltd. are precision seamless tubes manufactured to exact dimensional tolerances for hydraulic and instrumentation systems. The material is CK45 carbon steel, equivalent to DIN C45 and AISI 1045, with a carbon content of approximately 0.42-0.50%. These pipes are produced through cold drawing and rolling to achieve tight diameter and wall thickness control, with surface finishes suitable for direct machining or hydraulic assembly.
The cold rolling process enhances mechanical properties compared to hot-rolled equivalents, increasing tensile strength and reducing internal stress. Typical outer diameters range from 6mm to 100mm, with wall thicknesses from 0.5mm to 8mm. Surface roughness is typically Ra 0.4-0.8 μm, and dimensional tolerances follow DIN2391 Table 2, with OD tolerance ±0.05mm and wall thickness ±5%. No internal coating is applied unless specified by the buyer.
These pipes are primarily used in hydraulic cylinders, pneumatic actuators, fuel injection lines, and precision machinery components. Buyers include manufacturers of industrial automation equipment, automotive fluid systems, and hydraulic tooling suppliers. Orders are typically placed in lengths of 5m to 6m, packed in wooden crates or plastic-lined bundles. Trade terms are FOB Yantai or CIF, with payment via T/T or L/C. Minimum order quantities are not stated but are commonly negotiated at 1 metric ton per size.

Before ordering DIN2391 CK45 pipes from Yantai Xinpeng, confirm the exact outer diameter, wall thickness, and surface roughness against your design specifications. Request a sample for dimensional verification and surface inspection. Do not assume compliance with DIN2391 without documented test reports. Clarify whether the pipes are normalized or stress-relieved, as this affects machinability and weldability.
Logistics terms are typically FOB Yantai, but must be confirmed in writing. Lead times are not stated but generally range from 25 to 45 days after order confirmation, depending on size and quantity. Payment is usually 30% advance with balance against B/L copy. Ensure Incoterms are clearly defined, and specify whether packaging is in wooden crates with moisture barriers or plastic-lined bundles for sea transport.
Quality checks should include caliper measurements for diameter and wall thickness, surface roughness testing with a profilometer, and hardness verification with a portable tester. Request a sample batch for destructive tensile testing if used in critical hydraulic systems. All documentation must be in English and match the purchase order. Retain samples for independent lab testing if the application involves high pressure or safety-critical functions.
