Core Product Overview
This comprehensive sealing parts catalog features ASME B16.20/API 6A compliant gaskets, seal rings, O-rings, and flange gasketing kits engineered for critical fluid sealing applications across oil and gas production, water treatment packages, industrial pumps, pressure safety valves, and wellhead equipment. Target users include maintenance engineers, pipeline technicians, industrial pump repair specialists, oilfield asset managers, and procurement teams focused on eliminating flange leaks, preventing system downtime, and complying with strict pressure vessel standards. The core purpose of this catalog is to supply precision-manufactured, code-compliant sealing components that deliver zero-leak performance, withstand extreme pressure and temperature fluctuations, and extend the service life of flanged connections, valves, pumps, and wellhead assemblies.
Key Pain Points Addressed
- Costly Fluid Leak Incidents: Improper or worn gaskets cause hazardous fluid leaks, leading to regulatory fines, environmental cleanup costs, and unplanned shutdowns averaging $30,000+ per industrial system failure
- Premature Seal Failure: Non-compliant or low-grade gaskets degrade under high pressure (up to 1500 LB) and high temperature (up to 800°F), requiring frequent replacements and inflating maintenance costs
- Code Non-Compliance Risks: Using non-ASME/API certified sealing parts violates industry safety standards, risking equipment certification revocation and operational halts
- Mismatched Sealing Fit: Ill-sized gaskets and rings cause uneven compression, seal distortion, and chronic leakage in flanged joints, pump housings, and valve assemblies
2. Detailed Product & Technical Specifications
Functional Description
These sealing components perform critical roles in industrial and oilfield systems, with key functions including:
- Creating leak-proof flanged connections for pipelines, pumps, and wellheads across Class 150 to Class 1500 pressure ratings
- Sealing rotating pump shafts and bearing housings to prevent lubricant loss and fluid intrusion
- Maintaining pressure integrity in pressure safety valves and strainers to protect system equipment
- Sealing static joints in produced water treatment packages and industrial agitators
- Withstanding chemical exposure from crude oil, produced water, and industrial process fluids
Structural Characteristics
- Spiral-Wound Gaskets (33UAUB/33CACB): Layered metal winding (Inconel 625/304 SS) with flexible graphite filler, 4.5mm thickness, and carbon steel outer ring for compression control; designed for raised face (RF) flanges
- RTJ Octagonal Gaskets: Solid soft iron/316 SS construction, precision-machined to API 6A/ASME B16.20 specs, for RTJ flanges in high-pressure Class 900/1500 systems
- O-Rings: Molded Viton/NBR elastomers with consistent cross-sectional diameter, JIS B 2401/AS568 standard sizing, for static and dynamic sealing
- Mechanical Seals: Carbon/ceramic sealing faces with Viton secondary seals, engineered for centrifugal pump shaft sealing to reduce friction and leakage
Applicable Operating Conditions
- Pressure ratings: ASME Class 150, 300, 600, 900, 1500 LB
- Temperature range: -20°F (-29°C) to 800°F (427°C) for spiral-wound gaskets; -40°F (-40°C) to 450°F (232°C) for Viton O-rings
- Applications: Oilfield wellheads, Christmas trees, pipeline flanges, industrial pumps (ALLWEILER, EBSRAY), pressure safety valves, produced water treatment packages
- Fluid compatibility: Crude oil, produced water, industrial chemicals, lubricating oils, and process fluids
- Standards compliance: ASME B16.5, ASME B16.20, API 6A, JIS B 2401, NACE MR-0175
Maintenance & Service Recommendations
- Inspect all gaskets and O-rings for cracks, compression set, or corrosion prior to installation; discard damaged components immediately
- Clean flange faces thoroughly to remove debris, old seal residue, and rust to ensure even compression
- Torque flange bolts to manufacturer specifications in a cross-pattern to avoid uneven gasket compression and leakage
- Replace spiral-wound and RTJ gaskets every 24 months or after system pressure testing; replace O-rings annually or at the first sign of hardening
- Store sealing components in a cool, dry environment away from UV light and chemicals to preserve material integrity

3. Field Failure Repair Cases
Case 1: Flange Leak on Class 150 Pipeline (Spiral-Wound Gasket Failure)
A production facility experienced persistent fluid leakage on a 20” Class 150 pipeline flange. Inspection revealed a degraded non-compliant spiral-wound gasket with broken windings. Replacing the faulty gasket with a 33CACB ASME-compliant spiral-wound gasket eliminated leaks and restored system pressure integrity.
Case 2: Pump Shaft Leak From Worn Viton O-Ring
An IGF agitator in a produced water treatment package suffered lubricant leakage from the bearing housing. The issue was a hardened P170 Viton O-ring that lost elasticity. Installing a new JIS B 2401 compliant Viton O-ring stopped leakage and extended pump service life.
Case 3: Wellhead RTJ Gasket Leak (High-Pressure Failure)
An offshore wellhead with an 8” Class 900 RTJ flange developed a pressure leak due to a damaged soft iron RTJ gasket. Replacing the gasket with an ASME B16.20 certified 53CA octagonal RTJ gasket sealed the joint and restored wellhead pressure control.
4. Frequently Asked Questions (FAQ)
| Question | Answer |
| Are these gaskets compatible with ASME Class 150/300/900 flanges? | Yes, all spiral-wound and RTJ gaskets are manufactured to ASME B16.20 standards for direct fitment with Class 150 to Class 1500 raised face and RTJ flanges. |
| What materials are available for high-corrosion oilfield environments? | We offer Inconel 625 (33UAUB) and 316 stainless steel sealing components, along with Viton O-rings, for superior corrosion resistance in harsh oilfield and offshore conditions. |
| Do these O-rings meet standard sizing for industrial pumps? | All O-rings comply with JIS B 2401 and AS568 standard sizing, ensuring perfect fitment for ALLWEILER, EBSRAY, and other industrial centrifugal pumps and agitators. |
