Reliable Fastener Solutions for Petrochemical Plants
Petrochemical facilities run in harsh extreme environments: high temperature, high pressure, strong acid & alkali chemical medium, long-term salt vapor and outdoor weather erosion. Conventional carbon steel fasteners easily corrode, crack or loosen, which may trigger pipeline leakage and safety hazards.
XHT provides full series anti-corrosion industrial fasteners for refineries, chemical storage tank factories, pipeline engineering contractors and petrochemical equipment manufacturers. Our stainless steel bolts, alloy high-temperature fasteners, heavy-duty flange screws and locking nuts are suitable for distillation towers, reaction kettles, storage tanks and oil pipeline assembly.
All products comply with chemical industry safety standards, support bulk export orders and customized special corrosion-resistant fasteners.
Key Advantages for Petrochemical Working Conditions
1. Ultra Strong Chemical Corrosion Resistance
304/316 stainless steel & alloy materials resist acid, alkali, solvent and brine vapor, avoid rust perforation of pipelines and tower equipment.
2. High Temperature & High Pressure Stability
Special alloy fasteners keep stable mechanical performance under long-term high heat and pressure inside distillation towers and reactors, no deformation or fracture.
3. Anti-Vibration & Anti-Leak Locking Design
Deep thread and self-locking structure withstand continuous fluid vibration of oil pipelines, maintain tight sealing to prevent medium leakage.
4. Heavy Load Bearing Capacity
High tensile strength meets the load demand of large storage tanks, tower frames and high-pressure pipe flanges.
5. Long Service Life & Low Maintenance
No frequent replacement in corrosive chemical workshops, greatly reducing plant shutdown maintenance cost.
6. Full Safety Certification & Batch Testing
Each batch passes salt spray, high-low temperature, tensile and acid resistance tests, complete inspection documents for chemical factory safety audit.
Feature
- High tensile & yield strength, stable under high temperature, high pressure, widely used for petrochemical pipeline flanges and reaction equipment.
- Complete thread across the whole length, flexible matching for different thickness flanges, uniform clamping force to prevent leakage.
- Blackened surface resists slight oxidation and oil medium erosion, fit harsh chemical plant working environment.
