Question 1

What types of concrete pipe machines does Heliyuan Machinery manufacture?

Accepted Answer

Heliyuan Machinery manufactures a full spectrum of concrete pipe production equipment including Suspension Roller Concrete Pipe Machines, Vertical Rising Core Vibration Pipe Machines, Centrifugal Concrete Pipe Machines, and Precision Steel Pipe Molds for diameters ranging from 200mm to 3000mm. We also supply CNC steel cage welding machines, concrete batching plants, and gantry cranes for complete turnkey plants.

Question 2

What is the difference between a Suspension Roller and a Core Vibration pipe machine?

Accepted Answer

Suspension Roller machines utilize centrifugal roller compaction for dry/semi-dry concrete, ideal for standard drainage and stormwater pipes with high daily output. Rising Core Vibration machines use high-frequency vibration and hydraulic core-pulling, ideal for high-density, large-diameter, bell-and-spigot jacking pipes and high-pressure water mains with immediate demolding.

Question 3

How durable are Heliyuan cement pipe molds and what materials are used?

Accepted Answer

Our concrete pipe steel molds are fabricated from high-grade wear-resistant alloy steel (Q235/Q345 with reinforced longitudinal ribs). With precision CNC lathe machining and 600°C electric heat treatment annealing, Heliyuan molds deliver a service life exceeding 10,000 casting cycles with minimal tolerance deviation.

Question 4

Do you provide overseas installation, commissioning, and worker training?

Accepted Answer

Yes. Heliyuan Machinery provides turnkey overseas engineering services. Our experienced factory engineers travel directly to your factory site internationally to oversee foundation civil work, machine assembly, electrical commissioning, and operator training until the first batch of qualified concrete pipes is produced.

Question 5

Can you manufacture custom pipe molds for non-standard diameters or joint profiles?

Accepted Answer

Absolutely. We offer comprehensive OEM and ODM customization. We can engineer molds for Flat Flush joint, Tongue and Groove (T&G), Bell and Spigot (Socket), and Steel Ring Jacking joint profiles according to ASTM C76, BS 5911, DIN 4032, or AS/NZS 4058 standards.

Question 6

What is the typical delivery lead time and container shipping arrangement?

Accepted Answer

Standard molds and modular equipment ship within 15�?5 business days. Full automated production lines typically ship within 30�?5 days. We provide sea-worthy export packing, anti-rust coating, and full container load (FCL) packing plans for 20ft/40ft/40HQ and flat rack containers to ports internationally.
