One of oil and gas contractor in Iraq was carrying out an ongoing project, we received their procurement requirements which include included stainless steel pipes, ss flanges, PIG signallers, Stainless steel pipe fittings, bolts and nuts, as well as other metal components required for project construction.
We have competitive in this kind of Project RFQ is,and after reviewing the customer's RFQ, we provide our price list and company qualification docs,during one month contacting for all products details, the customer selected us as the supplier and placed an order based on their confidence in our product sourcing and project coordination capabilities.
316L stainless steel flange type PIG signaller is one of supplied products for this project

A PIG signaller is a pipeline monitoring device, and it always used to detect the liquid or other staff of a pipeline pig at a designated point in a oil&gas pipeline system.
When pipeline inspection, cleaning and maintenance, engineering need to use Pipeline pigs as their useful device.
For oil and gas projects, the signaller needs to be compatible with the pipeline configuration and suitable for the project site environmental and operating conditions.
There have carbon steel type and stainless steel type signaller, and For this project, Customer choose 316L stainless steel body,include strim and Flange and other components.
316L stainless steel is widely used in industrial and oil&gas applications,especially where corrosion resistance environment. 316L molybdenum content improved resistance to localized corrosion which better than 304 stainless steel
Customer site system is falnge pipeline system, so flange-type PIG Signaller allows our products could be integrated into the customer's existing system, providing a practical connection for installation and maintenance.Before confirming order, we provide details drawing for confirmation ,this was ensure our products could meet site requests.

The PIG signaller flange was specified with a DN450, Class 300, RF.
Nominal diameter: DN450
Pressure class: Class 300
Flange facing:Raise Face
Connection dimensions:2”
Material requirements:ASTM A182 316L

As a project-based supplier, we coordinated the production and inspection process according to the customer's technical requirements.
For the PIG signaller, quality control covered both the mechanical and functional aspects of the product.The inspection and verification are internal inspection and Third part inspection included:
Switch Continuity Test,Electrical Output Verification,IP / Ex-proof Verification,Material Traceability,Calibration / Trigger Verification,Functional Test
These checks were carried out to verify that the signaller met the specified functional and technical requirements before delivery.
As per customer request, we arranged A third-party inspection as per our arranged test plan,there have all request test points and details description.and finally passed inspections.

This delivery is part of our broader capability to support customers with stainless steel piping materials and related pipeline components.
Our core supply range includes stainless steel pipes, tubes, round bars and flanges in various grades and specifications. For project-based procurement, we can also coordinate related piping products and accessories, such as pipe fittings, bolts and nuts, and selected pipeline components according to customer requirements.
By coordinating material sourcing, production, inspection, documentation and delivery, we aim to provide customers with a more efficient supply solution for oil and gas and other industrial piping projects.
