on average
M-Seal Compact Flange is a widely used and more dependable
alternative to ANSI/API flanges. It incorporates our same
metal-to-metal sealing design as our M-LOK clamp connectors,
while offering a bolted flange configuration for those who
prefer a more compact and lightweight joint compared to
traditional ANSI/API designs.

Advanced Weld Overlay Solutions
Metalok360™ offers M-LOK® connectors with advanced
weld overlay solutions designed for demanding industrial
environments where corrosion, erosion, and wear resistance
are critical. Weld overlay technology provides a cost-effective
means of enhancing the surface properties of carbon and low-alloy
steels by applying a corrosion-resistant alloy (CRA) layer while
maintaining the structural integrity and strength of the base material.
In addition to providing superior corrosion protection, weld overlay significantly improves the mechanical performance of critical components, extends service life, reduces maintenance requirements, and lowers total lifecycle costs in severe-service applications.
To ensure the highest standards of quality and reliability, Metalok360™ performs comprehensive non-destructive testing (NDT) on all weld overlay components, including ultrasonic examination to verify overlay integrity, bond quality, and compliance with project specifications.
Metalok360™ NDT services provide independent validation of weld overlay quality prior to commissioning, helping identify potential defects before components are placed into operation. Early detection minimizes the risk of in-service failures, protects asset integrity, reduces unplanned downtime, and helps avoid costly repairs and remediation activities.
For applications exposed to aggressive corrosive or erosive conditions, Metalok360™ recommends the application of stainless steel or nickel-based alloy weld overlays on sealing and joint faces to maximize resistance to degradation and ensure long-term operational reliability.

Electroless Nickel Coating Services
Metalok360™ offers advanced Electroless Nickel (EN) coating services designed to enhance the performance, durability, and reliability of critical components operating in demanding industrial environments. Electroless Nickel coating provides a uniform, high-phosphorus nickel alloy deposit that delivers exceptional corrosion resistance, wear protection, and surface hardness, even on complex geometries and internal surfaces where conventional plating methods may be ineffective.
The autocatalytic deposition process ensures consistent coating thickness across all exposed surfaces, improving dimensional accuracy while minimizing post-processing requirements. Electroless Nickel coatings are widely utilized in oil and gas, petrochemical, mining, power generation, marine, and manufacturing industries where component longevity and operational reliability are paramount.
In addition to superior corrosion protection, Electroless Nickel coatings enhance resistance to abrasion, galling, and chemical attack, extending equipment service life and reducing maintenance costs. The coating also provides excellent release properties, improved lubricity, and can serve as an effective barrier against aggressive process fluids and environmental exposure.
To ensure the highest level of quality and performance, Metalok360™ works with qualified coating partners and conducts rigorous inspection and verification procedures to confirm coating thickness, adhesion, uniformity, and compliance with project specifications.
For components exposed to corrosive, erosive, or high-wear service conditions, Metalok360™ recommends Electroless Nickel coating as a cost-effective solution to improve asset integrity, minimize downtime, and maximize long-term operational performance.
