Product Description
3000 PSI Stainless Steel Stub Ends
Product Overview

The 3000 PSI Stainless Steel Stub Ends are precision engineered pipe fittings designed for demanding high pressure piping applications. Manufactured strictly to ASME B16.9 and MSS SP-43 standards, these lap joint stub ends provide a reliable and cost efficient method of creating flanged connections in oil and gas pipelines, petrochemical plants and power generation facilities.

Each 3000 PSI stub end is formed from premium stainless steel grades including SS304, SS304L, SS316 and SS316L, ensuring outstanding mechanical strength and long service life under elevated pressure and temperature conditions. The forged construction delivers a dense, uniform grain structure that resists fatigue and cracking, making these high pressure pipe fittings a trusted choice for engineers worldwide.

Quality Assurance

Our production facility operates under an ISO 9001:2015 certified quality management system. Every batch of 3000 PSI stainless steel stub ends undergoes chemical composition analysis, mechanical property testing and hydrostatic pressure verification before shipment. Dimensional inspections are performed with calibrated instruments, and each order can be supplied with complete mill test certificates, inspection reports and third party verification documents from SGS or BV upon request. With over 15 years of export experience, we have supplied high pressure pipe fittings to projects in Europe, the Middle East, Southeast Asia and the Americas.

Frequently Asked Questions
Q1: Can these 3000 PSI stub ends be used for sour gas service?
A: Yes. When ordered in SS316L or higher alloy grades, the 3000 PSI stainless steel stub ends offer excellent resistance to sulfide stress corrosion cracking, making them suitable for sour gas applications. Please specify your service conditions when placing the order.
Q2: What wall thickness options are available?
A: We supply wall thickness from Sch5S to Sch160. For high pressure 3000 PSI applications, we recommend Sch40 and above to ensure sufficient pressure holding capability. Our engineers can assist with thickness selection based on your design code.
Q3: Do you provide third party inspection for high pressure fittings?
A: Yes. We cooperate with SGS, BV, TUV and other independent inspection agencies. Third party inspection can be arranged at our factory or at the port of loading, covering dimensional checks, pressure tests and material verification.
Q4: What is the minimum order quantity for custom sizes?
A: The minimum order quantity is 1 piece for standard sizes. For custom diameters or non standard wall thickness, MOQ is typically 10 pieces. Small trial orders are welcome to verify our quality first.
