German Client Custom Concrete Pump Pipe Bend Solution

Client Background 

The client is a German manufacturer of concrete pump trucks, supplying equipment for large-scale construction projects across Europe. They required custom wear-resistant pipe bends for their concrete pumping system, with strict material specifications and a tight 30-day delivery deadline.

Pain Points Analysis

Short Lead Time – Delivery within 30 days, including design, production, and quality inspection.

Severe Abrasion in Use – Pipe bends in concrete pump trucks face continuous high-pressure flow of abrasive concrete slurry, causing fast wear.

High Dimensional Precision – Bends must match existing pipeline layout to ensure leak-free connection.

Zero Defect Acceptance – Any defect could lead to on-site downtime and costly project delays.

Haitian’s Solution

Rapid Engineering Review – Within 48 hours, our engineering team validated client drawings and confirmed curvature, wall thickness, and flange dimensions.

Material Selection – Used High Chromium Cast Iron with exceptional wear resistance and impact strength, specifically for high-abrasion slurry environments.

Precision Casting – Applied our DISA vertical molding line for consistent wall thickness and bend accuracy.

Special Heat Treatment – Employed precision quenching to increase hardness and surface strength without compromising toughness.

Strict Quality Control – Included inner surface smoothness inspection to reduce concrete flow resistance and extend service life.

Production & Delivery Timeline 

Day 1–2: Engineering review & raw material preparation

Day 3–15: Casting, machining, and heat treatment

Day 16–25: Quality inspection & client approval of samples
