Weld-On Connectors – ERW

We now offer weldable Box and Pin Multi Start Thread Connectors, suitable to be girth welded with ERW Pipes as per Specification API 5L. Weld-On Connectors are designed for Offshore and Onshore applications, where environmental conditions call for fast connector make-up combined with superior performance.
We use Leopard Connectors which combine the advantages of a preloaded thread-type connector with the rapid makeup, desired for offshore operations.
The Leopard Connectors have a high cone angle and are available in twin on four start thread. When stabbed, the box swallows approximately 90% of the pin length. The stabbing guide prevents cross-threading. Full make-up is achieved in less than half a turn with a four-start thread and less than one turn with a two-start thread.

Leopard Connectors have the following features:

Multi Start Threads for fast make-up
Low torque make-up with rig tongs less than one turn make-up
Integral 4 point anti-rotation provision
Suitable for piling
Reversible and reusable
Visual indication of make-up
Preloaded for fatigue

Weld-On Connectors are available as per the following details:

CHEMICAL COMPOSITION & MECHANICAL PROPERTIES

Tenaris Hydril Premium Connections

for demanding environment

Tenaris Hydril offers outstanding premium connection design and technology. The comprehensive range of high-performance products has been designed to meet the requirements of the most challenging applications.
Tenaris Hydril 3SB premium connections are available in Threaded & Coupled configurations with metal-to-metal seal.

Main Structural Differences:

The premium connections have 3 main features which separate them from the API connections:

Presence of shoulder,
Presence of a metal seal
And a different thread form.

Quality & Manufacturing

These premium connections are used when there are following requirements:

High performance in combined loads
High torsional strengths
Metal-to-Metal sealing
High galling resistance & controlled stress levels
Tight clearance situations

Tenaris Hydril Premium Connections are manufactured to same quality standards under the Quality Management System that Tenaris uses throughout its global manufacturing system.

Pipe Coating Facility

3L PE/PP, FBE, DFBE and Internal Coating (Liquid Epoxy)

3 LPE / 3 LPP Coating is anti-corrosive coating of 3 layers of epoxy, adhesive and PE / PP respectively on pipes, as per following details

1st Layer is of Epoxy coating which acts as an Anti-Corrosive Layer.
2nd Layer is of Adhesive coating which acts as a Tie layer between Epoxy and PE/PP.
3rd Layer is Polyethylene / Polypropylene coating which provides mechanical strength to the coating.

Advantages of Coated Pipes:

The coat begins on Bare Pipe with surface preparation by abrasive blast cleaning, phosphoric acid treatment, chromate treatment prior to the application of coat followed by electrostatic fusion bonded epoxy layer as primer, adhesive as tie layer, followed by high density Polyethylene/ Polypropylene layer as top coat.

Strong protective layer
Long term chemical and mechanical resistance
High mechanical impact strength and penetration resistance
Increases life span of pipes more than 25 years
Economy in the long term due to less repairing/ re-working

Applications & Specifications:

3 LPE Coating (DIN 30670) for service temperature upto
+80°C
3 LPP Coating (DIN 30678) for service temperature upto
+110°C
Single-layer FBE Coating (Canadian CAN/CSA Z245-06/ NACE RP 0394) for service temperature upto +80°C
Dual-layer FBE Coating (Canadian CAN/CSA Z245-06/ NACE RP 0394) for service temperature upto +80°C
Internal Flow coating (API RP 5L2/ISO 15741) for service temperature upto + 80°C
