Product Q&A

Q:Q1: What flange size and pressure rating does this bolt set suit?
A:
A1-EN: It is designed for 2 1/16 inch, 5000psi standard flanges, commonly used on oil- well wellhead fittings.
Q:Q2: Why does the configuration adopt one bolt with two nuts?
A:
A2-EN: Double-nut structure plays a locking effect, effectively preventing fastener loosening caused by pipeline vibration and pressure shock.
Q:Q3: Can I get other material options for this bolt-nut assembly?
A:
A3-EN: Multiple materials are optional, including carbon steel, alloy steel and stainless steel. We can customize surface treatments upon demands.
Q:Q4: Does this fastener comply with oil-industry bolt specifications?
A:
A4-EN: Thread size and mechanical property conform to UNC thread standards and A-P-I fastener requirements for wellhead flanges.
Q:Q5: Is the bolt-nut kit reusable after disassembly?
A:
A5-EN: It can be reused if the thread is intact and without deformation. Replace the set once threads are worn, cracked or stretched.
