Product Description En 10297 High Pressure 34CrMo4 Gas Cylinder Alloy Pipe 37mn 30CrMo4 34CrMo4 Alloy Seamless Steel Pipe for LPG CNG Cylinder1. Description: Honing is a kind of machining technology. Through honing head, the inner hole of cold drawn pipe is processed by reciprocating high-speed grinding technology, so that the inner hole can meet the requirements of tolerance size and surface roughness that we need.Honed tube is a kind of smooth bore steel tube used to manufacture hydraulic cylinder barrels that is the core part of a piece of hydraulic cylinder. 2. Commodity: St52.4 Honed Hydraulic Cylinder Precision Pipe3. Size range: Inside diameter: 25mm -500mm; Wall thickness: 2-50mm4. Available steel grade: SAE/AISI: SAE1020, SAE1026, SAE1045, SAE4130, SAE4140DIN: ST52, ST52.3, ST52.4EN: E355, C45E, 25CrMo4, 42CrMo4, CK45, S45C, E410, E470GB: 20#, 45#, 16Mn, Q345B, Q345C, Q345D, Q345E, 25Mn, 27SiMn, 5. Manufacture method: Cold rolled, hydraulic cold drawn, hot rolled+deep hole boring6. Delivery condition: BKBKWBKSGBKNBKQ+T+C+LC+SR+A+NCold rolledCold drawnStress relievedAnnealedNormalizedQuenched+Tempered7. Bore treatment: Honing, skiving&roller burnishing8.

Difference between honed tube and skived & roller burnished tube: In hydraulic cylinder industry, there are 2 solutions for bore treatment: Honing, and skiving&roller burnishing. Honing or skiving&roller burnishing leads to different internal surface image, but both ensure good roughness. Packing and ShippingFor 1/2" to 8" seamless steel tube, packaging always be in bundles with steel strip, 9'' and upper size will be in loose. Coating type: bare, varnish painting(anti-rusted painting), hot dipped galvanized, 3LPE, 3PP End protect: plastic ends cap, end protector. Packing: Bundled or each piece with knitted plastic bag, wooden cases or Ply-wooden Case.
