Product Description

Custom Length Stainless Steel Seamless Pipe ASTM A312 304/304L Beveled End Seamless Steel Tube

 

1.Product Description

This batch of stainless steel seamless pipes is supplied as ready-for-installation finished products per project drawings and Material Take-Off (MTO) lists. All pipes have undergone dimensional re-inspection, non-destructive testing, and surface cleaning at the mill. Ends are prepared with bevels (or plain ends) per welding procedure requirements and coated with a weldable end-protection layer. Each pipe is affixed with a waterproof label clearly indicating pipe number, material grade, size, heat/batch number, and installation zone code. On-site material verification is not required before proceeding directly to prefabrication and installation.

 

2. Product Applications

This batch of pipes is intended for direct one-time installation on site, covering the following specific construction scenarios:

  • Ground-level prefabrication and elevated hoisting/laying of pipe-rack overhead lines

  • Trench-laying and butt-welding of buried pipelines (with anti-corrosion field-joint coating coordination)

  • Piping connections to equipment nozzles (pump suction/discharge, heat exchanger nozzles, tower connections)

  • Pipe section connections in confined spaces (valve clusters, instrument fitting spool pieces)

  • Temporary prefabrication of modular pipe spools (facilitating future overall replacement)

3. Product Advantages

  1. Zero on-site preparation: Pipes are cut to specified lengths and beveled at the factory. No cutting, chamfering, or grinding is required upon arrival, allowing immediate fit-up and saving approximately 30% of on-site fabrication man-hours.

  2. Anti-mistake pipe marking: Color codes (e.g., red = steam, blue = water, yellow = flammable media) are sprayed within 1m of each pipe end, complemented by QR code scan tracking linked to electronic records, eliminating on-site material misuse.

  3. High hoisting safety: Tight OD ovality ensures stable clamping by tongs or slings with balanced center of gravity, preventing slippage or swinging during overhead lifting.

  4. Convenient welding fit-up: Pipe end ovality ≤0.5% OD (cold-drawn); consistent bevel angle and land thickness allow easy control of root gap and misalignment, reducing welder difficulty and improving first-pass yield.

  5. Low-temperature applicability: Maintains sufficient toughness even at -5℃ to -20℃ ambient temperatures. Winter construction preheating requirements are lower than for equivalent welded pipes, reducing on-site heating equipment needs.

  6. Coating compatibility: External weldable rust-preventive primer ensures good adhesion with on-site epoxy/polyurethane field-joint coatings and insulation layers.
