Suzhou, Jiangsu, China — The 30th China International Trenchless Technology Conference and Exhibition (ITTC 2027) will take place on April 21-23, 2027 at the Suzhou International Expo Center, Halls C1 and D1. As the longest-running trenchless event in Asia, ITTC marks a milestone 30 years of showcasing horizontal directional drilling (HDD), pipe jacking, pipe bursting, cured-in-place pipe (CIPP), and pipeline inspection technology to a global audience.
Organized under the guidance of CSTT (China Society for Trenchless Technology) and supported by the International Society for Trenchless Technology (ISTT), ITTC is the must-attend event for anyone involved in underground utility construction, pipeline rehabilitation, or HDD rig sourcing in the Chinese market.
The 29th edition (ITTC 2026), held in Tianjin in April 2026, set new records: 20,000 square meters of exhibition space, 121 exhibiting companies, 21 first-time exhibitors, and over 80% of exhibitors displaying full-size working equipment rather than static models. The show covered HDD rigs ranging from small 6-ton units for residential utility work to large 600-ton machines for river and highway crossings.
For international buyers of HDD drilling rigs, ITTC is the single best venue to compare Chinese manufacturers side by side. Major players like XCMG, Vermeer China, Ditch Witch China, and numerous specialized HDD builders all occupy booths in the same hall, making it possible to compare torque ratings, rod pull-back forces, mud pump capacity, and pricing in a single day.
China now manufactures the majority of HDD rigs sold worldwide, particularly in the 20-600 kN thrust/pull-back range. Brands like XCMG, Drillpipes, and various Shandong-based builders offer HDD units at 40-60% lower prices than Western equivalents, with comparable specifications. At ITTC, you can:
Compare multiple brands under one roof: Instead of visiting factories scattered across Jiangsu, Henan, and Shandong, you see all major HDD manufacturers in a single exhibition hall. You can compare rotary head torque, thrust/pull-back force, rod speed, and mud flow specifications on the spot.
See full-size machines running: Over 80% of exhibitors bring actual working equipment. You can watch an HDD rig operate, inspect the control system, and ask engineers technical questions face to face.
Meet pipeline contractors and end users: ITTC draws municipal pipeline companies, gas utilities, telecommunication cable installers, and water authority procurement teams. It is not just a sales channel — it is where you can learn what the Chinese domestic market actually demands.
The 2026 show highlighted several trends that will shape the 2027 event: battery-electric HDD rigs for urban emission-restricted zones, remote-control operation for dangerous conditions, real-time drill navigation with GPS-guided sonde tracking, and smart mud recycling systems that reduce water consumption by 70%. Chinese manufacturers are increasingly offering Tier 4 / Euro V engine options for export markets.
For buyers in Africa, Southeast Asia, Central Asia, and South America — markets where HDD pipeline installation is growing rapidly — ITTC is where you will find the best balance of price, reliability, and after-sales support.
Visitor registration is free and opens on the ITTC official website (en.cstt.org.cn) approximately two months before the show. If you are an international buyer looking to source HDD rigs directly from Chinese factories, we can help you with factory tours, price negotiation, translation, and shipping arrangement before, during, and after the expo.
We supply horizontal directional drilling rigs from 20kN to 600kN, with factory-direct pricing, DDP delivery, and full after-sales support worldwide.
