X70Q API Line Pipe Supply for Iran Oil and Gas Pipeline Project

We have completed a large-scale high-grade pipeline steel supply project for HELIGAN SANAT Co., a professional energy engineering enterprise in Iran. The total supply capacity reaches 5879.3 metric tons of premiumX70Q line pipes, serving local large-diameter oil and gas transmission pipeline construction.

X70Q line pipe is a high-strength API standard pipeline steel with excellent low-temperature toughness, superior weldability and stable compressive resistance. It is widely used for long-distance, high-pressure oil and gas transportation pipelines, perfectly adapting to Iran’s complex geological conditions and harsh outdoor operating environments. This ultra-large-volume project fully demonstrates our strong mass production and export capacity of high-grade line pipes, further consolidating our market position in the Middle East energy pipeline industry.

Project Challenge

This 5879.3-ton X70Q bulk line pipe project brought prominent challenges in mass production consistency, strict technical standards and cross-border delivery arrangement: 1.High-Strength Steel Technical Requirements: X70Q grade line pipe requires precise control of chemical composition and mechanical properties. Every batch must pass strict tensile, impact and hydrostatic pressure tests to meet high-pressure pipeline operation standards. 2.Mass Production Consistency Control: For ultra-large orders, maintaining unified dimensional tolerance and stable performance across all production batches is critical to ensure overall pipeline assembly accuracy and operational safety. 3.Large Shipment Scheduling Pressure: The 5879.3-ton super-large order requires scientific phased production and batch shipment planning to match the client’s continuous engineering construction progress. 4.Strict Import Document Compliance: Iran’s energy engineering procurement requires complete standardized English test reports and certification documents to support smooth customs clearance and project acceptance.

Our Solution

To ensure stable quality, consistent performance and on-time delivery for this large-scale X70Q line pipe project, we implemented full-process standardized solutions: 1.Precision Standardized Production: We adopted exclusive rolling and heat treatment processes for X70Q line pipes in strict accordance with API standards. Strict raw material screening and real-time process monitoring ensured stable mechanical performance of each pipe. 2.Full-Batch Strict QC Inspection: All products underwent comprehensive dimensional calibration, mechanical performance testing and non-destructive inspection. Full sets of qualified test reports were provided to guarantee 100% product qualification rate. 3.Optimized Phased Delivery Plan: We formulated scientific batch production and shipment schedules based on the total order volume. Real-time communication with the client ensured flexible adjustment of delivery rhythm to fit on-site construction progress. 4.Complete Export Document Support: We sorted out full English certification documents, factory inspection reports and shipping files in advance to meet Iran’s import customs clearance and engineering acceptance requirements. This project fully verifies our outstanding strength in large-volume manufacturing and cross-border export of high-grade X70Q line pipes. It further deepens our long-term cooperative relationship with Iranian energy engineering clients and expands our influence in the Middle East oil and gas pipeline supply market.
