Import Cut Pipes — Buy in Bulk from Supplier in China

Cut pipes from Beijing Better Product International Ltd. are precision-machined sections of ASTM A733 and ASTM A687 carbon and alloy steel tubing, with threads conforming to ANSI/ASME B1.20.1. Pipe diameters range from 1/8 inch to 6 inches, with wall thicknesses matching ASTM specifications for schedule 40 and 80. Each pipe is cut to length with a maximum tolerance of ±0.5 mm and deburred internally to prevent flow restriction.

ASTM A733 pipes are made from low-carbon steel with a maximum carbon content of 0.30%, while ASTM A687 pipes use medium-carbon steel with controlled manganese and silicon levels. Thread profiles are precision-cut to ANSI B1.20.1 standards, with a pitch tolerance of ±0.05 mm and no thread damage beyond 10% of the length. Surface finish is typically mill scale or pickled, with optional phosphating for corrosion resistance.

These pipes are used in industrial plumbing, HVAC refrigerant lines, and oil and gas instrumentation systems where leak-tight connections are critical. Buyers include manufacturers of pressure vessels, chemical processing equipment, and HVAC contractors. Orders are typically placed in batches of 50 to 500 pieces, packed in steel crates or wooden pallets. Trade terms are FOB Tianjin or CIF port of destination, with lead times of 25 to 35 days after order confirmation.

Beijing Better Product International Ltd. is registered at No. 18 B602, Yianjiayuan, Beiwaxili, Haidian District, Beijing. The company sources and exports cut pipes manufactured by third-party mills in China. The listing does not state whether the supplier operates a production facility or acts as a trading company. No information is provided about years in business, workforce size, or certifications beyond the generic mention of ISO and BIS.

The supplier has no verified response rate or public track record on the platform. Its profile suggests it aggregates product listings from multiple manufacturers rather than producing pipes directly. The technical accuracy of the product description implies some engineering oversight, but no factory audit reports, material test certificates, or quality control procedures are disclosed in the source data.
