A Decision with Significant Implications
This situation tends to occur too frequently: a project manager is lured by a polished catalog and a good price, and as a result, procures flanges from a vendor they have never worked with before. The visually acceptable flanges are installed, but weeks later an assembly develops a leak when the system is pressurized.
The cause is determined to be a dimensional non-conformance. The flanges were never compliant to the ASME B16.5 standard, which they were offered as.
It is very costly and disruptive to have to replace flanges that were installed during a project, and it could have been entirely preventable. This all begins with selecting an flange manufacturers in India that focuses on quality.
The Flange Manufacturing Sector and Why India is Winning
In the last 20 years, India's manufacturing hub in Mumbai, Pune, and Gujarat has emerged as one of the best places to source industrial flanges. Indian manufacturers have gained a significant advantage amongst buyers in the Middle Eastern, European, and Southeast Asian markets. This is attributed to the growing international standard practices, skilled metallurgical knowledge, and price competitiveness.
The hospitality of Indian flange manufacturers may be a strength, but in many cases it is their downfall, and in order to avoid the latter, the following will help.
Things to Consider Prior to an Order
- Material Certifications and Traceability
A good manufacturer will provide material test reports along with the flanges, and they will provide full traceability to the original heat for all the steel they provide, be it carbon, stainless, or alloy.
- Standard Compliance
Choose manufacturers who conform to recognized international standards when producing flanges.
- ASME B16.5 — Pipe flanges and flanged fittings
- ASME B16.47 — Large diameter steel flanges
- EN 1092-1 — European standard for pressure equipment flanges
- API 6A — Flanges for wellhead and Christmas tree flange equipment
Manufacturers who understand multiple standards offer you flexibility for varied project requirements.
- Range of Flange Types Available
Leading manufacturers in India have complete stocks of flanges such as:
- Weld Neck Flanges
- Slip-On Flanges
- Blind Flanges
- Socket Weld Flanges
- Lap Joint Flanges
- Threaded Flanges
- Spectacle Blind Flanges
Having so many offerings means there’s a range of manufacturing capabilities and not just a list of products.
Important Questions to a Supplier
Get the answers to the following questions prior to placing an order:
- Is your manufacturing done in-house or through third-party mills?
- Do you allow third-party inspections by SGS or Bureau Veritas?
- What are your lead times for flanges with standard dimensions vs. those with custom dimensions?
- Do you have experience in international trade?
The answers to the above questions will get you more useful information than any product catalog.
