Note: The thickness is available with Sch5, Sch10, Sch30, Sch40, Sch80, Sch120, Sch160, STD, XS, XXS, 5S, 10S, 40S, 80S, etc.

application

  • Special pipeline layout: Used for connecting pipes of different diameters with offset axes, addressing space constraints or pipeline avoidance requirements (e.g., bypassing beams, columns, or equipment).
  • Anti-liquid accumulation design: Features a single-sided horizontal transition to prevent liquid from accumulating at the bottom of the pipeline, suitable for applications such as pump inlets and horizontal process pipelines where anti-clogging is required.
  • Key industries: Chemical processes, oil and gas transportation, and water treatment systems where both diameter changes and drainage functions are required.

advantages

  1. Flexibility in space: Special structure realizes non-coaxial diameter changes, solves installation space conflict. Straight pipe bottom allows easy cleaning and drainage of liquids (no liquid pockets).
  2. Improvement fluid efficiency3) Conical design low turbulence (less pressure loss), highly appropriate for solid content/viscous media.
  3. Structural Reliability: Seamless pipes equal to pressurization can withstand higher & higher pressure & work, and it changes over time. Ensures zero-leakage sealing in the long run at welded joints.
  4. Material Versatility: American system carbon steel ASTM A234, an economic type of materials for the conventional industrial pipe line. 304 or 316L stainless steel to satisfy amphistaic corrosion-resistance and food, pharmaceutical and hygiene standard .

packing

  • Precision Protection Plan:
    • Surface Treatment: Rust prevention, hot-dip galvanizing (outdoor/high-humidity environment), acid washing and passivation (stainless steel corrosion prevention)
    • Single-Sided Foam: Wrap custom foam in eccentric areas to prevent deformation due to transport impact.
  • Tiered Packaging Strategy:
    • Small Diameter (≤6″): Conductors bundled with caps on ends
    • Large Diameter (>6″): One-piece wooden box + internal steel frame fixation, center of gravity to be taken seriously.
  • Smart Identification System:
    • Installation direction was clearly same with Arrows + text arrows (top flat / bottom flat).
    • Printing of outer box specification (for example, DN200→DN150 bottom flat), material code and anti-tip mark

Note: The thickness is available with Sch5, Sch10, Sch30, Sch40, Sch80, Sch120, Sch160, STD, XS, XXS, 5S, 10S, 40S, 80S, etc.

  • Special pipeline layout: Used for connecting pipes of different diameters with offset axes, addressing space constraints or pipeline avoidance requirements (e.g., bypassing beams, columns, or equipment).
  • Anti-liquid accumulation design: Features a single-sided horizontal transition to prevent liquid from accumulating at the bottom of the pipeline, suitable for applications such as pump inlets and horizontal process pipelines where anti-clogging is required.
  • Key industries: Chemical processes, oil and gas transportation, and water treatment systems where both diameter changes and drainage functions are required.
  1. Flexibility in space: Special structure realizes non-coaxial diameter changes, solves installation space conflict. Straight pipe bottom allows easy cleaning and drainage of liquids (no liquid pockets).
  2. Improvement fluid efficiency3) Conical design low turbulence (less pressure loss), highly appropriate for solid content/viscous media.
  3. Structural Reliability: Seamless pipes equal to pressurization can withstand higher & higher pressure & work, and it changes over time. Ensures zero-leakage sealing in the long run at welded joints.
  4. Material Versatility: American system carbon steel ASTM A234, an economic type of materials for the conventional industrial pipe line. 304 or 316L stainless steel to satisfy amphistaic corrosion-resistance and food, pharmaceutical and hygiene standard .
  • Precision Protection Plan:
    • Surface Treatment: Rust prevention, hot-dip galvanizing (outdoor/high-humidity environment), acid washing and passivation (stainless steel corrosion prevention)
    • Single-Sided Foam: Wrap custom foam in eccentric areas to prevent deformation due to transport impact.
  • Tiered Packaging Strategy:
    • Small Diameter (≤6″): Conductors bundled with caps on ends
    • Large Diameter (>6″): One-piece wooden box + internal steel frame fixation, center of gravity to be taken seriously.
  • Smart Identification System:
    • Installation direction was clearly same with Arrows + text arrows (top flat / bottom flat).
    • Printing of outer box specification (for example, DN200→DN150 bottom flat), material code and anti-tip mark
