Customized Titanium Slip-On Flanges - CNC Machined OEM by China Suppliers | High-Quality Factory Production
Product Description
A slip-on flange is a type of flange connected to a vessel or pipe via a fillet weld. It is classified as a non-welded flange. During design, it is verified as either a welded flange or a loose flange, depending on the degree of integration between the flange ring and the straight pipe section. Flange rings come in two types: necked and neckless. Compared to necked butt-weld flanges, slip-on flanges have a simpler structure and require less material, but their rigidity and sealing performance are inferior to those of necked butt-weld flanges. Slip-on flanges are widely used in the connection of medium- and low-pressure vessels and pipelines.
With years of experience in titanium manufacturing, Yesheng Titanium Industry specializes in producing titanium alloy slip-on flanges (SO), tailor-made for various harsh corrosive working conditions as core components for high-performance pipe connections. We use high-quality titanium ingots, shaped by forging and refined by precision CNC machining.
While retaining the core advantage of easy installation of slip-on flanges, the integrated short neck structure greatly enhances the rigidity and load-bearing capacity of the flange, achieving a perfect balance of economy, practicality and corrosion resistance.
Core Advantage
1. Excellent Corrosion Resistance
A dense and stable oxide film (TiO2) naturally forms on the surface of titanium metal. This protective film can effectively resist erosion from harsh media such as seawater, chloride ions, wet chlorine, hypochlorite, most organic acids, and strong alkalis. Its resistance to corrosion, pitting, and stress corrosion cracking is far superior to that of 316L stainless steel. No additional anti-corrosion coating or cathodic protection is required during use. It remains rust-free and does not contaminate the transported medium for long-term use, with a service life of more than 20 years. This can significantly reduce equipment maintenance and component replacement costs, saving long-term operating expenses for enterprises.
2. High Strength & Light Weight
Titanium has similar strength to steel but only 57% of its density. Using titanium alloy slip-on flanges can effectively reduce the load on pipelines, equipment, and supporting structures. This advantage is particularly prominent in scenarios sensitive to self-weight, such as offshore platforms, ships, and large chemical plants, which can improve the operational stability of the entire system. At the same time, the short neck design can effectively disperse the stress at the pipe connection and enhance flange rigidity. Compared with ordinary plate-type slip-on flanges, it can adapt to higher pressure and temperature working conditions, reducing potential operational safety hazards.
3. Easy & Efficient Installation
This flange adopts a slip-on welding method. Pipes can be directly inserted into the flange bore without complex bevel processing, featuring low welding difficulty and high construction efficiency, which can effectively shorten the construction period. In medium and low-pressure corrosive pipelines, its comprehensive cost is much lower than that of high-alloy stainless steel flanges and welding neck flanges. It can not only meet the working condition requirements but also control the procurement cost, with significant cost-effectiveness advantages.
4. Precision Manufacturing
From titanium ingot selection to finished product delivery, the whole process adopts forging + CNC precision machining technology to ensure that the dimensional accuracy meets the standard, the sealing surface is smooth and flat, and the pipe connection is tight without leakage. Each product is equipped with an original material certificate and mechanical property report, with full quality traceability, allowing customers to use it with more confidence.

Frequently Asked Questions
Q1: What is a titanium slip-on flange?
A: A slip-on flange is a type of flange connected to a pipe via a fillet weld. It slides over the end of the pipe and is welded both inside and outside to provide sufficient strength and prevent leakage. It is widely used in medium and low-pressure corrosive pipelines.
Q2: Why should I choose titanium flanges over stainless steel?
A: Titanium offers superior corrosion resistance against seawater, chlorides, and organic acids, preventing rust and contamination. It is also much lighter (57% density of steel) while maintaining similar strength, resulting in a service life of over 20 years with lower maintenance costs.
