DIN17175 Alloy Pipes from Big Co., Ltd. are seamless tubes manufactured in China to European standards for high-temperature and high-pressure industrial applications. The material grades available include 15Mo3, 13CrMo44, ST35.8, and ST45.8, each selected for thermal stability and mechanical strength under sustained operational stress. These pipes are produced using controlled rolling and heat treatment processes to ensure consistent microstructure and dimensional accuracy across batches.
The alloy composition of 15Mo3 and 13CrMo44 provides enhanced creep resistance compared to standard carbon steels, making them suitable for boiler tubes, superheaters, and heat exchangers in power plants. ST35.8 and ST45.8 grades offer lower alloy content but maintain adequate tensile properties for moderate-temperature systems. Wall thickness tolerances follow DIN17175 Table 2, typically ±10% of nominal, and outer diameters range from 10mm to 219mm. Surface finish is mill scale unless otherwise specified, with no internal polishing unless requested.
These pipes are commonly purchased by engineering contractors for oil and gas refineries, chemical processing units, and utility boiler installations. Buyers typically order in lengths of 5.8m to 7m, packed in bundles with steel straps and moisture-resistant wrapping. Trade terms are usually FOB Qingdao or CIF destination, with payment via T/T or L/C. Minimum order quantities are not stated but are typically negotiated based on grade and size availability.

Sourcing DIN17175 Alloy Pipes from Big Co., Ltd. - China Import Guide
Before ordering DIN17175 alloy pipes from Big Co., Ltd., verify the exact material grade, heat treatment condition, and wall thickness tolerance against your project specifications. Request a certified mill test report for the specific heat number to be shipped. Do not assume compliance with DIN17175 without documented proof, as some suppliers may mislabel carbon steel as alloy grade. Confirm the surface condition and whether pickling or coating is required for your application.
Logistics terms are typically FOB Qingdao or CIF, but must be confirmed directly. Lead times are not stated but generally range from 30 to 60 days after order confirmation, depending on grade and quantity. Payment is usually 30% advance with balance against copy of B/L. Ensure Incoterms are clearly defined in writing, and clarify whether packing is in wooden crates or steel strapping, as this affects customs clearance and handling costs.
Quality checks should include ultrasonic testing for internal flaws, dimensional verification with calipers, and hardness testing on representative samples. Request a sample batch for destructive testing if the project involves critical pressure systems. All documentation, including test reports and packing lists, must be in English and match the purchase order. Retain samples for third-party inspection if the shipment is large or the application is safety-critical.
