Why Contractors Specify NUPROS

Full size and pressure range

NUSEAL joints are produced from 1/2" through 100"+ and rated from ANSI 150 to ANSI 2500 and API 10000+, covering virtually every onshore pipeline and station application without the need for a secondary supplier.

750-ton press, in-house fabrication

A 750-ton hydraulic press, multiple TIG/MIG/ARC welding sets, and 5-ton EOT cranes allow NUPROS to manufacture heavy-wall and large-bore components entirely in-house, reducing lead-time risk for EPC schedules.

NABL-accredited material testing

Physical, chemical, microstructural, and hardness testing is conducted in an NABL-approved laboratory on-site, supporting EN 10204 3.1 and 3.2 material certification with full traceability.

Integrated QHSE management system

Simultaneous certification to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 reflects a single integrated management system, which simplifies contractor vendor qualification audits.

Configurable to client specifications

End connections (butt weld, WNRF, RF, RTJ), coating thickness, insulation material grade (NEMA G10/G11), and testing requirements are all configurable, so no standard product compromise is required.

Established in export supply since 1999

NUPROS has supplied EPC and cathodic protection contractors in Saudi Arabia, Kuwait, and the United Arab Emirates, building a documented export track record for projects where vendor history is a qualification criterion.

Sourcing FAQ

What pipe sizes and pressure classes are available for NUSEAL monolithic insulation joints?

NUSEAL joints are manufactured from 1/2" to 100"+ nominal pipe size. Pressure ratings cover ANSI Class 150 through ANSI Class 2500 and API 10000+. End connections available include butt weld, WNRF, raised face (RF), and ring-type joint (RTJ).

What insulation material is used, and what coating is applied?

Insulation is NEMA G10 or G11 thermosetting epoxy composite, selected based on service temperature and pressure class. Internal and external protective coatings are applied to a minimum thickness of 150 microns.

Is NUPROS a manufacturer or a trading company?

NUPROS PVT LTD is a manufacturer. Products are fabricated in-house at an 850 m² workshop equipped with a 750-ton hydraulic press and in-house welding and testing facilities.

Which material certifications and quality standards apply?

NUPROS holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. Material certification is issued to EN 10204 3.1 or 3.2 upon request. Testing is performed in an NABL-approved on-site laboratory covering physical, chemical, microstructural, and hardness analysis.

Which HS codes cover these products?

Monolithic insulation joints and gasket assemblies typically fall under HS 8484.10 (gaskets and similar joints) or HS 7307.99 (pipe fittings). Flow measurement spools may be classified under HS 9026.80. Buyers should confirm classification with their customs authority.

Which export markets does NUPROS currently serve, and can it supply to new geographies?

NUPROS currently exports to India, Saudi Arabia, Kuwait, and the United Arab Emirates. The company targets EPC and CP contractors across the Middle East, Southeast Asia, and Africa. Inquiries from other regions are welcome via the form below.
