STREN-FLEX
Frequently asked questions
Common questions about STREN-FLEX from 3G Electric.
What is the difference between STREN-FLEX Type 3 and Type 9 web slings?
STREN-FLEX Type 3 web slings are flat-eye slings, where the eyes are formed by folding and stitching the webbing flat. Type 9 slings are attached-eye cargo slings, typically with a single leg and eyes that are attached rather than formed from the main body. Both types are available in nylon or polyester, with various ply counts and lengths. The choice depends on the rigging configuration, load shape, and required eye orientation. Type 3 slings are common for general lifting, while Type 9 slings are often used for cargo handling and applications where an attached eye is preferred.
What materials are used in STREN-FLEX web slings?
STREN-FLEX web slings are constructed from nylon or polyester webbing. Nylon offers elasticity and abrasion resistance, while polyester has low stretch and good resistance to UV and moisture. Some slings are described as high-visibility, using colored webbing for easier identification. Ply count varies from 1 to 4 or more, affecting strength and thickness. The webbing is stitched to form eyes, and a wear-resistant tag is attached for identification. The material and ply count determine the sling's capacity and suitability for specific environments. Buyers should match the sling material to the load, environment, and inspection requirements.
What sizes of STREN-FLEX pipe chocks are available?
STREN-FLEX pipe chocks are available in at least two sizes: a regular model with overall dimensions of 5 in length, 2 1/4 in width, and 2 3/8 in height, and a large model with 8 in length, 3 in width, and 3 1/2 in height. Both are made of plastic in orange. They are used to secure pipes and cylindrical loads during transport or storage, preventing rolling. The size selection depends on the pipe diameter and the required stability. These chocks are part of the STREN-FLEX line of load-securing accessories.
How are STREN-FLEX slings identified for inspection?
Many STREN-FLEX slings include a wear-resistant tag that carries identification information, such as the manufacturer part number, sling type, and possibly capacity and length. This tag supports inspection and record-keeping, as required by rigging safety programs. The tag is designed to withstand wear and environmental exposure. Inspectors can reference the tag to verify the sling's specifications and check for damage or wear. The presence of a tag does not replace the need for regular inspection of the sling body, eyes, and stitching. Users should follow applicable inspection intervals and criteria.
What sling lengths and eye lengths are available for STREN-FLEX web slings?
STREN-FLEX web slings are available in various sling lengths and eye lengths. Examples include sling lengths of 8 ft, 12 ft, and 16 ft, with eye lengths of 10 in, 11 in, and 12 in. The specific combination depends on the sling type, material, and ply count. Longer slings are used for larger rigging spans, while eye length affects the attachment to hooks or shackles. When selecting a sling, consider the required reach, the load dimensions, and the connection points. The manufacturer part number encodes these dimensions, allowing precise ordering.
Can STREN-FLEX slings be used in abrasive environments?
Some STREN-FLEX web slings are described as abrasion-resistant, such as the nylon flat-eye sling with a 16 ft length and 1-ply construction. Abrasion resistance depends on the webbing material and construction. Nylon generally offers good abrasion resistance, and additional edge protection may be present in protected-edge designs. For abrasive environments, inspect slings frequently for cuts, fraying, or worn edges. The wear-resistant tag helps maintain identification even in harsh conditions. Always follow the manufacturer's guidelines for use and inspection in abrasive applications.
