LBTC-311 Large-Deformation Extensometer for Tensile Testing of Geotextiles in Wide Strips

The extensometer chuck is specifically designed to accommodate large‑deformation extensometers and is used in tensile testing of geosynthetic materials—including needle‑punched geotextiles, woven geotextiles, nonwoven geotextiles, geogrids, geomembranes, and more—under conditions involving significant strain. It provides secure specimen clamping, with adjustable gripping settings tailored to specimen size and material properties, ensuring that the specimen remains stable during testing without slipping or tilting, while maintaining consistent clamping force that avoids damage. The device complies with standards such as JTGE 50 “Test Procedures for Geosynthetics in Highway Engineering” and GB/T 15788‑2017 “Method for Tensile Testing of Wide‑Strip Geosynthetics.”

Do you supply full-set testing instruments for asphalt and geotechnical engineering projects?

We offer complete lab solutions including asphalt viscosity tester, asphalt rutting tester, geotextile permeability tester, low-temperature flexibility tester and concrete/cement test equipment, covering raw material detection for road, water conservancy and construction engineering projects

Can you customize fixtures or test machines based on our special test requirements? How about after-sales service and warranty?

We provide non-standard customization of test equipment and customized fixture clamps according to customers’ specimen size and test standards. All our testing machines enjoy 12-month factory warranty; overseas customers get remote online debugging guidance, spare parts supply and technical operation training. Our products have been exported to over 70 countries globally

Which materials can be measured by your Vicat softening point tester?

It measures heat deflection temperature and Vicat softening temperature of plastics, hard rubber, nylon, insulating materials and fiber-reinforced thermosetting composites. Intelligent temperature control guarantees precise heating rate, ideal for plastic raw material incoming inspection and formula development in plastic factories.

Does your pipe pressure burst testing machine control test temperature automatically? What’s its main application?

Yes, the constant-temperature circulating system keeps stable test environment during long-time hydrostatic resistance and instant burst pressure measurement of thermoplastic pipes. It complies with GB6111 standard and serves raw material inspection, new product R&D for plastic pipe manufacturers, third-party testing labs and university laboratories.

What kinds of pipes fit your ring stiffness tester? Can it do long-term creep testing?

This equipment is designed for HDPE, PVC corrugated pipes, plastic drainage pipes and various plastic tubular products. Apart from ring stiffness, ring flexibility and flattening tests, it supports continuous long-term creep tests up to 1000 hours (42 days) as required by industry specifications, widely used for pipe factories and construction quality inspection institutes.

What test items can your WDW series computer-controlled electronic universal testing machine complete? Which international standards can it meet?

Our WDW universal tester is applicable for tension, compression, bending, shearing and peeling tests of metal, plastic, rubber and composite materials. It supports test procedures in accordance with GB, ISO, ASTM, DIN, JIS multiple domestic and global standards. Equipped with high-precision servo drive and dedicated test software, it automatically collects, calculates and exports test data including tensile strength, elongation at break and elastic modulus.
