Inquiry checklist
When inquiring, state: size, wall/SCH, grade, standard, qty; for elbows also radius and angle; non-standard parts can be made to drawing or sample.

A stainless steel 180° butt-weld return reverses the direction of a pipe run. HuaboPipe supplies returns to order, with bend radius, center-to-center distance and end dimensions checked against the drawing.

How to choose

Check the return against the available installation space and the two pipe centerlines. Send center-to-center distance as well as nominal size. Replacing a return with two 90° elbows changes the assembly and adds a joint; the designer must confirm dimensions, weld access and inspection requirements.

FAQ

Which dimensions are essential?

Provide DN or NPS, outside diameter, wall thickness, bend radius, center-to-center distance, material, standard and quantity. Mark any special end preparation or tolerances on the drawing.

Can two 90° elbows replace a return?

Only after the layout and fabrication requirements have been checked. It is not an automatic equivalent: joint position, fit-up and inspection access can differ.

Is DN3000 a standard 180° return?

No. Standard sizes are DN15 to DN1200. Larger returns, up to DN3000, are made to drawing.

How is delivery time confirmed?

Send the completed specification, quantity and inspection requirements. Price and lead time are confirmed after review.

Prepare your inquiry

Send the dimensions, material, quantity and inspection requirements above. Include the drawing revision and delivery destination so the quotation can be checked against the same specification.
