Import Alloy Steel Pipe Fitting — Buy in wholesale FOB from Supplier in China

Hebei Cangrun Pipeline Co., Ltd. supplies alloy steel pipe fittings in sizes from 1/2 inch to 24 inches, with wall thickness schedules ranging from Sch10 through Sch160. The material is chrome-molybdenum alloy steel meeting ASTM A234 WP11 or WP22 grade requirements, chosen specifically for service in high-pressure and high-temperature piping systems. Each fitting receives sand blasting as standard face treatment and beveled ends for butt welding preparation. Surface finish and end preparation are critical for weld integrity in oil and gas transmission lines, petrochemical process plants, and power generation boiler circuits.

ASTM A234 WP11 and WP22 are low-alloy steels with elevated chromium and molybdenum content, providing creep resistance at sustained temperatures above 400 degrees Celsius and improved resistance to hydrogen attack in sour service. WP11 typically contains 1.00-1.50% chromium and 0.44-0.65% molybdenum, while WP22 carries 2.00-2.50% chromium and 0.87-1.13% molybdenum. The Sch10-Sch160 schedule range covers thin-wall light applications through heavy-wall high-pressure service, with heavier schedules (Sch80 and above) common in process piping rated for Class 600 and higher pressure classes. Sand blasting removes mill scale and prepares surfaces for NDE inspection and coating adhesion. Bevel ends follow ASME B16.9 dimensional tolerances, typically 37.5 degrees plus or minus 2.5 degrees for standard butt weld geometry.

These fittings serve oil and gas upstream production facilities, downstream refineries, petrochemical crackers and reformers, and fossil fuel and combined-cycle power plants. Buyers include EPC contractors, maintenance procurement teams, and project material controllers sourcing for API 650 storage tank piping, ASME B31.1 power piping, or B31.3 process piping. The wooden box or pallet packaging specified protects machined bevels and threads during ocean freight from Chinese ports. Confirm with Hebei Cangrun Pipeline Co., Ltd. whether supplementary requirements from ASTM A234 (S1 through S9) are available, including radiographic examination, impact testing, or macrotech testing for weld seam integrity.

Hebei Cangrun Pipeline Co., Ltd. is located at Lianmeng Road, Haowei Building, Shijiazhuang City, 050600, Hebei Province, China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and an average response time of zero hours recorded. These signals indicate limited active engagement through the platform messaging system, so direct communication via the supplier's listed contact channels is advisable for time-sensitive inquiries.

The company profile does not state a manufacturing or trading designation, specific year of establishment, employee count, annual revenue, named clients, or third-party certification holdings. What can be confirmed is the stated address in Shijiazhuang, the product focus on alloy steel pipe fittings for high-pressure service, and the explicit material grades and dimensional ranges offered. Buyers should verify directly with Hebei Cangrun Pipeline Co., Ltd. whether the company operates as a manufacturer with in-house forging and heat treatment capabilities, or as a trader sourcing from Hebei province's established steel fitting production base. Requesting a factory audit or video inspection may clarify production control and welding procedure qualification status.
