ASME R-STAMP MODIFICATIONS & REPAIR

Certified Repair Solutions for Exotic Metal Equipment

At Tinita Engineering Pvt. Ltd., we offer specialized repair and refurbishment services for exotic metal equipment, both on-site and at our manufacturing facility. Our repair work is carried out by certified welders and engineers, strictly following ASME “R” Stamp, IBR, and ISO standards to ensure safety, performance, and regulatory compliance.

Our Repair & Service Offerings

Repair of Titanium-Lined, High-Pressure, Multi-Layered Equipment

We have experience in fixing complicated process equipment that has Titanium, Tantalum and other reactive metals on it. This equipment is used in high-pressure and corrosive environments like chemical reactors and digesters. These repairs are very important for maintaining the structural integrity of the base material (usually carbon steel) from corroding. We often perform Exotic material welding, Titanium welding, and precision work that needs to be done in controlled environments to keep them from getting contaminated and brittle.

Our Services include:

Repair of cracked or eroded liners
Re-welding of joint areas under Class 8 cleanroom conditions using certified R stamp welding protocols
Internal inspection, NDT, and requalification

Re-Tubing of Shell & Tube Heat Exchangers

We offer specialized re-tubing services for tough materials like Titanium, Hastelloy, Inconel, and Duplex alloys. These materials are necessary for services that deal with high temperatures, high pressures, and harsh chemicals like sulfuric acid and chlorides.

We manage:

Complete tube bundle replacement
Fabrication and installation of a replacement tube bundle
Tube-to-tube sheet weld repairs
Comprehensive hydro testing and third-party inspection

These services often involve Heat exchanger welding and large-scale heat exchanger tube bundle replacement projects.

On-Site Fabrication & Welding of Exotic Metal Piping

We conduct on-site welding and fabrication of pipelines made from Titanium, Tantalum, Zirconium, Niobium, and Nickel Alloy pipelines. This service minimizes plant downtime by allowing rapid field installation of process-critical lines, often in tight or hazardous areas. Our work includes:

Strict welding procedures (GTAW, SMAW, purging, trailing shields)
Controlled Titanium welding services for field applications
On-site inspection, passivation and documentation

Repair of Exotic Metal Piping Networks

Piping networks that are exposed to corrosive service, like streams that are very acidic or caustic, often need localized, time-sensitive repairs. We offer targeted solutions to extend the life of these costly assets, so you don’t have to replace them frequently.

We offer:

Patching, flange replacement, and weld joint restoration
Precision work using Titanium welding in sensitive zones
Argon purging and back shielding to maintain weld integrity

Suitable for acid plants, chlor-alkali units, and bromine-processing environments.

In-House Equipment Repair & Rework at Tinita’s Workshop

At our dedicated workshop we handle comprehensive repairs and modifications that require specialized tooling, heavy lifting capabilities and maximum environmental control. This setting allows for the most complex Exotic material welding and alignment corrections. we handle:

Refurbishment of pressure vessels, columns, and heat exchangers
Removal of corroded sections and weld overlay repair
Dimensional correction, pressure testing, and QA revalidation
All heavy repair tasks are supported with advanced Exotic material welding procedures.

Our services support both CAPEX upgrades and OPEX repair needs, helping clients extend the life of their critical assets while minimizing downtime.

Compliance Standards for All Repairs

Every repair and fabrication activity is carried out under strict regulatory frameworks to ensure the highest levels of safety, integrity, and operational reliability. Compliance is non-negotiable and is managed by a dedicated QA/QC team.

ASME “R” Stamp for both field and shop repairs
IBR compliance
Third-party inspections by EIL, BV, TUV, Lloyd’s, Velosi

Our commitment to quality and safety ensures:

Across all services whether Titanium welding, Heat exchanger welding, or tube bundle replacement, our commitment remains the same:

Weld integrity
Metallurgical compatibility
Long-term, zero-leak performance
