SAE J529 engineering machinery high pressure fuel oil injector pipe
High Precision Seamless Steel Tube for Automotive Industry and Hydraulic Application
Περιγραφή: __________:
Synopsis of Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends.
The raw material we choosing:high quality Bao Steel,XingCheng Steel and HuaiSteel.Physical and chemical inspection will be made to make sure each batch is in qualified range. After piecing,each piece of tube is checked to be in permitted size deviation,this can garantee higher thickness tolerance and concentricity.
Production process quality control: We use the domestic first-class drawing machine,the production process is controlled with high hardness alloy internal and external matrix,so the product dimensions tolerance and ovality are strictly controlled in high level.Through the first, middle and last process inspection to ensure product quality.
Inner and Outer Surface Cleaning: We adopt automatic inner surface cleaning machine, rotating brush cleaning and high pressure oil flushing to clean the inner and outer surface.The new steel tube production craftsmanship can effectively remove all particulate attached to the inner and outer surface of tubes and thus achieving the utmost surface cleaness and polishness.
Finished tube anti-rust oil plating: We adopt high pressure spray plating method, the antirust oil is plated by high pressure jet after ten passes of filtering and one pass of precipitation to safeguard the tubes’ outer and inner surface cleaness and polishness.

J525 Hydraulic Tube is welded low-carbon steel tubing annealed for bending and flaring with many uses. Used for pressure lines in applications requiring high-quality tubing for bending, flaring, forming, and brazing. Typical uses include Heavy Equipment, Agriculture, Off-Road Vehicles, Automotive, Steering and Transmission components, Process and Utility, and other Hydraulic applications.
Επιπλέον, the manufacturing process of our J525 high-pressure tubing includes several cold-drawn reductions, intermediate anneals, and then a dead-soft anneal after final sizing. The resulting tubing is consistent of high quality that is easy to bend and flare.
Much like J524, J525 is used in hydraulic applications, both with the same chemical and mechanical properties. The difference is that J525 is welded starting as flat stock. Where flaring is a requirement, J524 Seamless is typically the preferred product. Όμως, both are of high quality and have comparable specifications.

Welded Low-Carbon Steel Tubing Suitable for Bending,Flaring,Beading,Forming and Brazing
The SAE J526 Standard covers electric-resistance welded single-wall low-carbon steel pressure tubing intended for general automotive, ψύξη, hydraulic, and other similar applications requiring tubing of a quality suitable for bending, flaring, beading, forming, and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path that would be caused by the ID weld bead. The material produced to this specification is intended to service pressure applications where severe forming and bending is not required. As this material may exhibit mechanical properties that reduce some desired forming characteristics versus SAE J356, the severity of the forming requirements of the finished assembly should be considered when utilizing material produced to this specification.Εάν χρειάζεστε περισσότερες πληροφορίες,παρακαλώ επικοινωνήστε μαζί μας sales@grandsteeltube.com -

ASTM A519 specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified

1.A copper plated steel strip is pulled into the primary tube rollers, and become 720 degrees wrapped after going through a set of the rollers.
2.Then the wrapped tube goes into the welding chamber where the tubes are brazed. The temperature within the chamber is controlled above the copper melting temperature, so the copper layers are melted and spread into the steel surfaces. The tube is heated here in the chamber with protection gas filled so there is no oxidizing of the copper or steel, and also no water will be left to avoid any rust.
3.After the welding stage, the tube goes into the cooling section where it gets cooler, and also it is monitored online simultaneously by the Eddy current scanning device. Any abnormal section shape or un-seamed welding would be observed from the monitor screen.
4.The tubes are finally wound to be easily packed and stocked.
This process of Bundy tube production, compared with other methods, are widely accepted for its high production rate yet instant monitoring of the welding quality.
