Phosphated Hydraulic Tube - China

EN 10305-4 Black Phosphate Steel Tubes

EN10305-4 E235+N/DIN1630 St37.4 Black Phosphate Steel Tubes

Seamless precision steel tubes for hydraulic usage Description: galvanized or phosphate seamless cold-drawn precision steel tubes for hydraulic and pneumatic lines with improved corrosion protection.

Tolerances: according to EN 10305-4 "Steel tubes for precision applications – Technical delivery conditions- Part 4: Seamless cold drawn tubes for hydraulic and pneumatic power systems".

Steel grade: E235 (St-35/37.4) Delivery condition: +N (NBK) normalized under a controlled atmosphere.

Internal and external phosphate coating; Externally galvanized tubes with a zinc coating of 8 to 12 μm and subsequently chrome VI-free passivated (blue or iridescent silver).

Synopsis of Process Routing: quality carbon steel → cold drawing → bright heat treatment without oxidization (NBK status) → nondestructive testing.

In the wall honing and inside flushing under the high pressure→ plastic capping on both ends→Phosphating→Anti rust oiling outside surface→Bundles Main Features: high accuracy, excellent brightness, no oxidization on the outer and inner walls after heat treatment, high cleanness inside wall.

The steel tube is able to stand high pressure.

No deformation after cold bending, no crack after flaring and flattening.

The complicated geometrical forming and machining can be realized.

bright black.

Color is homogeneously distributed on the tube surface.

The tube has good properties of antirust Main Application: to be used in hydraulic systems, automobiles, s and in the occasion where the high precision, brightness, cleanness, and mechanical properties of the tube are required.

Main grades: ST35, ST45, ST52, E215, E235, E355, etc.

Delivery Status: NBK(+N)+Black Phosphating Main Application: - Phosphated hydraulic tube is mainly used in hydraulic systems.

• Business Description: Shanghai T.S. Industrial Co., Ltd focuses on Finned Tubes, Fin Tube, and Finned Pipe used in Heat Exchangers, Boiler Economizers, Coolers, and Heaters.
  
  We supply custom fin tubes and finned pipes in various material configurations that will increase the heat exchangers' heat transfer rate and reduce operating costs.
  
  With an advanced high-frequency resistance welding finned tube production line, an annual production capacity of up to 4000 tons, the specifications of phi 22-273mm finned tube, according to national standards or customer requirements standard production.
  
  The company produces finned tubes (square fin tube, circular finned tube, spiral fin tube, H type finned tube, longitudinal fin tube, corrugated fin tube, spiral serrated fin tube, needle-shaped fin tube, plate-shaped fin tube, inner fin tube) that can be applied to the boiler, air preheater, etc.
  
  Fin tubes or called finned tubes are a major component for various heat recovery systems.
  
  The close connection between the Finning operation and the manufacturing plant allows significant savings in packaging and freight as well as working capital reduction as a result of a “just-in-time” supply chain.
  
  T.S. Industrial Supply and produce to custom requirement finned tubes.
  
  For high-frequency resistance welding finned tube.
  
  The fin, either solid or serrated, in carbon, alloy, or stainless steel is helically wound around the tube and resistance welded.
  
  For Extruded Finned Tube, the Base tube can be carbon steel, alloy Tube, and stainless steel, while the fin can be aluminum and copper alloy.
  
  Typical product, we also produce extruded serrated finned tubes.
  
  For Bending, We can be on the bare tube and also can be over the fin, is performed on-site with custom-designed duplex benders.
  
  In our typical finned tube supply range, we supply both extruded fin tubes and helical welded finned tubes, which are mainly used for the heat transfer industry.
  
  Specific types such as Embedded Fin Tube also called G Type Fin Tube, L Fin Tube, LL Finned Tube, KL Finned Type also call knurled Finned Tube, Extruded Fin Tubes, Extruded Serrated Fin Tube, Square Fin Pipe also call H Fin Tube, Rectangular Fin Pipes also called Double H Fin Tube, Longitudinal Finned Tubes, Studded Tube and Nailhead Pipe, High-Frequency Welded Serrated Fin Tube, High-Frequency Welded Solid Fin Tube.
  
  T.S. Industrial privately owned company and finned tube manufacturer.
  
  We are not owned by, nor do we own, any steel producers.
  
  Our independence from steel producers ensures that we are objective in matching exact customer needs in terms of quality, specifications, and delivery.
  
  T.
  
  S Industrial provides finned pipes products and services to the power plants, petrochemical industries, boiler & heat exchangers, nuclear stations, paper, shipbuilding sectors as well as refrigerating industries.
  
  Incorporated with manufacturers and fabricators in China, we can supply in accordance with most international standards with high-qualified and cost-effective products.
  
  Our main strength lies in the heat exchanger tubular, especially finned tubes, which can be long up to twenty meters, and usually delivered in U-bent form.
  
  We are confident that our expertise in this field will bring you high-value-added products & services, and we are ready anytime to team up with your finned tube solutions.
