Industry Pain Points: Difficulty in Balancing Efficiency and Precision in Traditional Processing Modes

In bridge-tunnel engineering, the small conduit acts as the core component of the support structure, and its processing quality directly affects construction safety and progress. Traditional processing methods rely on manual operations, which have three major pain points: Firstly, the processing efficiency is low, and the processing of a single conduit requires multiple steps such as cutting, bending, and welding, with manual operation taking as long as 15-20 minutes per conduit, making it difficult to meet the needs of large-scale construction; secondly, precision control is difficult, and manual measurement errors can easily lead to deviations in conduit bending angles exceeding ±2°, and welding position offsets exceeding 3mm, affecting the stability of the support structure; thirdly, the safety risk is high, as high-temperature welding, mechanical operations, and other links are prone to cause work-related injuries, and manual fatigue work further aggravates safety hazards. A bridge-tunnel project once had to be redone due to insufficient conduit processing precision, resulting in direct economic losses exceeding 500,000 yuan, highlighting that the traditional model is no longer adaptable to modern construction requirements.

Currently, the equipment has been serving national key projects such as the Chengdu-Tibet Railway and the Hong Kong-Zhuhai-Macau Bridge. A project feedback shows that after using Xuhui's production line, the qualified rate of conduit processing increased from 85% to 99.2%, and the construction period was shortened by 20%.

FAQ Q&A Selection Guide

Q1: How to select the core parameters for the fully automatic small tube production line?
A: Pay close attention to three key parameters when choosing:Scope of ProcessingThe coverage should include the commonly used conduit diameters (such as φ42-φ89mm) and lengths (3-6m).Bending accuracyPrioritize equipment with an angle error of ≤±0.5°.Welding EfficiencyThe robot welding speed must be ≥15 pieces/hour, and it supports quick changeover of multi-specification conduits. Taking Xu Hui's production line as an example, its standard model can process conduits with φ42-φ108mm, with a bending accuracy of ±0.3°, welding speed of 20 pieces/hour, and changeover time of only 5 minutes, meeting the high-intensity construction requirements for high-speed railways, large tunnels, etc.

Q2: What is the composition of the equipment quotation and what are the costs for after-sales maintenance?
A: Quotations generally include three parts: the main machine, control system, and auxiliary tools. Taking Xu Hong's production line as an example, the standard configuration quotation is approximately 850,000-1,200,000 yuan, varying depending on the processing scope and level of automation. Two points need to be paid attention to for the cost of later maintenance:Service Life of Vulnerable PartsIf the bending mold needs to be replaced every 5,000 pieces processed, the cost is approximately 2,000 yuan.Service Response SpeedXuhui offers 24-hour remote support and 48-hour on-site maintenance services, with an annual maintenance fee of approximately 3%-5% of the total equipment price, significantly lower than the industry average.

Q3: How to verify the actual processing effect of the equipment?
A: Can be verified in three steps:Step 1: On-site trial processingThe supplier is required to provide sample processing services, with a focus on inspecting indicators such as bending angles and welding strength.STEP 2: View Case DataPlease provide at least 3 usage reports for similar projects, focusing on key data such as processing efficiency and pass rate.STEP 3: Evaluate After-Sales ServiceUnderstand the spare parts supply cycle, technical personnel allocation, and other situations. Xuhui once provided free trial processing services for a tunnel project, with 100 pipes processed passing third-party inspection and fully complying with GB/T 1499.2-2018 standard, winning the client's long-term cooperation.
