2019 Customized Best Quality Black Plastic Thread Protectors
Custom Black Plastic Thread Protectors for Connection Identification
Black plastic thread protectors cover matching pipe threads during transportation and storage. Specify HDPE or ABS as the approved polymer grade, then match the protector geometry to the pipe connection drawing. Black color identifies appearance; it does not alone establish material grade, UV resistance or an impact rating.
For mixed pipe stocks, identify the protector by pipe family, complete connection designation and pin or box end. Agree item markings and packing labels so black protectors with similar appearance can be distinguished without relying on color alone.
All-plastic and metal-plastic composite protectors require separate construction specifications. For a custom black molded item, agree dimensions, tolerances and identification details together with fit and coverage checks. A color match cannot establish thread interchangeability.
Order data: pipe family, nominal size, connection designation, pin/box end, drawing revision, engagement length, seating clearance, coverage, polymer grade, black color requirement and quantity. The broader 2-3/8 to 20 inch range, NC/REG references and BTC/STC/LTC references require separate drawing and availability review.

Our company
Shanghai Qinuo supplies molded plastic components and oilfield accessories. Custom black protectors are reviewed by connection geometry and approved item reference.
Provide connection drawings, the selected HDPE or ABS grade and any color reference. Include required markings and packing identification for mixed-size orders.
Confirm tooling and sample fit before production. Agree readable item identification and packing references that remain consistent with the approved order.
ISO 9001 applies to quality management. If outdoor exposure or handling performance is required, define the material, conditions and acceptance tests separately from the black color specification.
Connection, black color and marking preparation:
FAQ
1. Can black color identify the correct connection?
Color alone is insufficient when different protector items share the same appearance. Use connection and end labels linked to the order.
Confirm the full designation and drawing revision before fitting a protector to the pipe end.
2. What identification should be agreed?
a. Approved item reference.
b. Complete connection designation.
c. Pin or box end orientation.
d. Nominal size and relevant drawing reference.
e. Selected HDPE or ABS grade.
f. Agreed black color reference and marking method.
g. Batch and packing references where required.
3. Does black plastic establish outdoor durability?
1. Confirm the actual polymer grade and formulation.
2. Define sunlight, temperature and storage exposure.
3. Agree applicable exposure checks and acceptance limits.
4. Review evidence for the selected molded design.
5. Keep color acceptance separate from exposure performance.
4. How should mixed black protector batches be checked?
1. Match item and packing labels to the order.
2. Confirm connection and pin/box orientation.
3. Inspect for damage or molded distortion.
4. Check fit, seating, coverage and removal.
5. Record mismatches by item and batch reference.
Other colors, connections and composite constructions require separate item specifications.
