Made in HoustonPython Slings
Python Pipe Restraint Slings are designed for one job: keeping pipe, conduit, and tubular loads from rolling during the lift. Holloway Houston manufactures the Python line in three duty ratings, light, medium, and heavy, color-coded so rigging crews can identify the right sling at a glance without reading the tag. Lengths run from 4 feet through 20 feet, covering the range from small-bore pipe bundles to large-diameter tubulars on oilfield and industrial worksites.
Python Pipe Restraint Slings for Lifting and Restraint
A pipe restraint sling is a synthetic sling with a cradle geometry designed to capture round loads and prevent lateral movement during the lift. Unlike a flat web sling, the Python's body conforms to the pipe, distributing contact force across a broader surface area rather than concentrating it at the edge of a flat strap.
Holloway Houston manufactures Python Slings in-house at its Houston, Texas facility. The line covers light, medium, and heavy duty ratings, identified by color (red, blue, and orange, respectively), so the correct rating is visible without stopping to inspect the tag.
Python Slings are manufactured to the requirements of ASME B30.9 (Slings) and meet WSTDA WS-1 standards for synthetic web slings. Every sling leaves the plant with a permanently attached identification tag showing the serial number, working load limit, and sling characteristics.
Duty Ratings and Available Lengths
Light Duty (Red)
Light duty Python Slings are rated for smaller pipe bundles and lighter tubular loads. Available in 4-foot, 10-foot, and 20-foot lengths, priced from $23.72 to $101.35. Red color coding identifies the light duty rating at a distance.
Medium Duty (Blue)
Medium duty Python Slings handle intermediate load sizes. Available in 4-foot, 10-foot, and 20-foot lengths, priced from $31.82 to $135.01. Blue color coding identifies the medium duty rating.
Heavy Duty (Orange)
Heavy duty Python Slings are rated for large-diameter pipe, heavy tubulars, and high-weight bundles. Available in 4-foot, 10-foot, and 20-foot lengths, priced from $45.81 to $194.23. Orange color coding identifies the heavy duty rating.
Where Python Pipe Restraint Slings Are Used
- Oil and Gas Pipe Yards : Bundling and picking tubular goods for yard transfers and transport staging without marring the pipe surface.
- Construction Sites : Hoisting conduit, structural pipe, and mechanical piping on commercial and industrial builds.
- Oilfield Workovers : Moving drill pipe, casing, and tubing at the wellsite where load security during the pick matters as much as the lift itself.
- Fabrication Shops : Handling pipe sections and assemblies during fabrication and fit-up operations.
- Pipeline Laying : Picking and positioning pipe in the trench or on the laydown area before welding.
Why Holloway Houston for Python Slings
Holloway Houston has been manufacturing rigging and lifting equipment in Houston for over 65 years. The Python Sling line is an in-house product, designed, fabricated, and tagged at our Houston facility, not sourced from a third-party manufacturer. ISO 9001 certification governs our manufacturing quality system.
Every Python Sling ships with the WSTDA-required identification tag. Slings needing replacement after inspection are easy to reorder by tag number directly through Holloway Houston. Our rigging inspection team can also evaluate sling condition in the field per ASME B30.9 and OSHA 1910.184.
Sling Inspection Awareness
Python Pipe Restraint Slings are synthetic slings governed by ASME B30.9. A sling showing cuts, tears, abraded yarns, heat damage, missing or illegible tags, or distorted end fittings is generally removed from service per ASME B30.9 inspection criteria. Holloway Houston's rigging inspection specialists can evaluate condition for slings in active fleets and provide documentation for equipment records.
Frequently Asked Questions
A pipe restraint sling is a synthetic sling designed to cradle round loads
during lifting and prevent rolling or lateral movement. Unlike flat web slings,
the Python Sling's profile wraps around the pipe profile, distributing contact
across a wider area. Holloway Houston manufactures the Python line in light,
medium, and heavy duty ratings in 4-foot, 10-foot, and 20-foot lengths.
Color coding on Python Slings identifies the duty rating at a glance, red
for light duty, blue for medium duty, and orange for heavy duty. This is
Holloway Houston's proprietary duty-rating color system and is not related to
WSTDA WS-1 capacity color codes, which use a different scheme for rated load
classes. Rigging crews read the color without stopping to inspect the printed tag.
Python Slings are manufactured per ASME B30.9 (Slings) and meet the
requirements of WSTDA WS-1 for synthetic web slings. OSHA 1910.184 governs
sling inspection and use in general industry. Each sling ships with a permanently
attached identification tag as required by ASME B30.9.
Yes. Holloway Houston's rigging inspection specialists can evaluate sling
condition in the field per ASME B30.9 and OSHA 1910.184 criteria. Slings removed
from service after inspection are easy to reorder through Holloway Houston by referencing the
serial number on the original tag.
Standard lengths are 4 feet, 10 feet, and 20 feet in all three duty ratings.
