FAQ
Q: What material grades do you use for SCH40 Carbon Steel Pipe Caps?
A: Our standard SCH40 pipe caps are manufactured from premium ASTM A234 WPB carbon steel, which offers optimal strength and weldability for high-temperature and ambient services. We can also provide ASTM A420 WPL6 for low-temperature environments, as well as various alloy and stainless steel grades upon request.
Q: Do your SCH40 pipe caps come with beveled ends?
A: Yes. All our butt-weld pipe caps feature precise Beveled Ends processed in strict accordance with ASME B16.25. This ensures flawless alignment and easy welding on-site. Plain ends can also be customized.
Q: What quality certifications and inspection documents do you provide?
A: Cangzhou Hangxin is an ISO 9001:2015 and CE-certified factory. For every shipment, we provide a Mill Test Certificate (MTR) according to EN 10204 3.1, detailing the exact chemical composition, tensile strength, and hardness test results. Third-party inspections (SGS, BV, etc.) are welcome.
Q: How do you guarantee the quality of large-diameter (24" to 72") pipe caps?
A: While sizes up to 24" are seamless, large-diameter caps are produced via advanced hot-pressing with welded seams. To guarantee 100% safety under high pressure, all welded caps undergo rigorous Non-Destructive Testing (NDT), including Radiographic Testing (RT/X-Ray) and Ultrasonic Testing (UT) to ensure zero welding defects.
Q: What is your standard lead time and packaging for export orders?
A: Our standard delivery time is 7 to 25 days after order confirmation, backed by our 13,000-ton annual capacity. All products are packed in sea-worthy, heavy-duty wooden cases or fumigation-free pallets with internal moisture-proof wrapping to ensure they arrive in perfect condition.
Based on the years of the technical precipitation and production experience, we provide hundreds of (easy to use, reliable, low price) products for the whole world wide clients and projects.
