ASME B16.11 A105N Threaded Full Coupling NPT X BSPT Galvanized Steel Coupling

Threaded Coupling NPT X BSPt Class 3000 A105N ASME B16.11 Steel Pipe Coupling

Coupling Threaded End

Forged pipe coupling is a short piece of pipe with female threaded end or socket weld end. Threaded end coupling is available in many thread types, the most popular types are NPT, BSPP and BSPT. The two thread end can be the same or different thread type, such as NPT x NPT, NPT x BSP. However, different threads can not be connected together

ZIZI ENGINEERING is China leading manufacturer and export of forged pipe fittings, we supply full size range coupling with threaded end in various materials.

Quality Control of Class 3000 Coupling

1. Surface

Hand touch and visual check the surface of threaded coupling

2. Dimension

Measure the size of the OD., end to end, threads length of threaded couplings, make sure they are in tolerance.

3. Marking

The marking should cover product name, diameter, pressure, thread type, material, standard and lot No..

For example, “ Socket 2” BSPP 3000LB UNS6600 B16.11 NP957”.

4. Threads

Test the threads with go/no go gauge.

5. Third party inspection

BV, SGS, LR, DNV, ABS.

ASME B16.11 Pipe Fittings Delivery

Package

For forged pipe fittings, we use at least three layers package to protect their good conditions.

Each of Inconel 600 threaded coupling will be dipped into anti rust oil and then put into plastic bags. Then packed them into carton box, the outside of box will be tagged a label to show the product information, including the product picture, item, size, material and quantity. Finally put the box into wooden cases.

Delivery Port

Shanghai, Tianjin, Qingdao port or as customer requirement.

Document

CI, PL, CO, BL, MTC for each clinet.
