ASME A333 Pipes - Low Temperature Service Steel Pipes

Product Overview

ASME A333 Pipes are precision-engineered carbon and alloy steel pipes designed specifically for low-temperature service where standard pipes fail. Our 42-year manufacturing expertise delivers impact-tested pipes that maintain structural integrity at sub-zero temperatures down to -320°F (-195°C). With ISO 9001 certified quality and 30,000-ton annual capacity, you get reliable ASME A333 Pipes that prevent brittle fracture in cryogenic applications. Our normalized heat treatment and controlled chemistry ensure consistent notch toughness for LNG terminals, petroChemical plants, and arctic installations.

Key Features & Advantages

Impact-Tested Reliability

Mandatory Charpy V-notch testing at specified temperatures ensures your pipes won't fail under low-temperature shock loads. Our Grade 6 pipes pass -50°F impact tests consistently.

Controlled Microstructure

Fine-grain practice and normalizing heat treatment eliminate internal stresses. You get uniform wall thickness and predictable mechanical properties throughout the pipe body.

30,000-Ton Production Capacity

Our dedicated production lines guarantee stable supply for large-scale projects. No delays on critical installations requiring bulk quantities.

Precision-Engineered Beveling

Ready-to-weld pipe ends with accurate bevel angles reduce your field preparation time. Dimensional tolerance per ASTM A530 ensures perfect fit-up.

Manufacturing Process

Seamless Production

Hot-pierced billets undergo controlled rolling and sizing. Normalizing heat treatment at 1650°F followed by air cooling creates uniform grain structure.

Quality Heat Treatment

Our controlled atmosphere furnaces ensure complete austenite transformation. Temperature monitoring at ±25°F maintains consistent mechanical properties.

100-Meter Automated Painting Lines

Eco-friendly sandblasting removes mill scale. Automated coating application provides uniform surface protection.

Surface Finish & Coating Options

Standard Finishes

· Mill finish per ASTM requirements

· Shot-blasted to SSPC-SP6 commercial grade

· Pickled and oiled for corrosion resistance

Protective Coatings

· Black paint finish for general service

· Galvanized coating for marine environments

· Epoxy coating for buried applications

Applications

LNG & Cryogenic Systems

ASME A333 Pipes handle liquid natural gas transfer lines where temperatures reach -260°F. Grade 8 provides reliable service in LNG terminals.

Petrochemical Processing

Cold cracking units and refrigeration systems require impact-resistant piping. Our Grade 6 pipes serve ethylene plants and ammonia facilities.

Arctic Pipeline Networks

Permafrost regions demand pipes that resist thermal shock. Controlled chemistry prevents brittle failure during temperature cycling.

Power Generation

Steam condensate systems and cooling water circuits benefit from improved toughness during startup/shutdown cycles.

We also supply matching low-temperature A350 LF2 flanges and A420 WPL6 fittings for a complete piping solution.

Packaging & Delivery

Protective Packaging

Pipe ends capped with plastic protectors. Bundle strapping prevents movement during transport. Wooden skids for heavy wall pipes.

Global Logistics Network

Dedicated shipping solutions for Central Asia and Middle East projects. Container optimization reduces freight costs by 15-20%.

Documentation Package

Mill test certificates, impact test reports, and dimensional inspection data accompany each shipment.

Customization Service

Cut-to-Length Services

Precision cutting eliminates field waste. Tolerances held to ±3mm for random lengths, ±6mm for specific cuts.

Threading & Grooving

NPT threading per ASME B1.20.1. Victaulic grooves machined to specification for mechanical coupling systems.

Special Chemistry Modifications

Enhanced sulfur resistance for sour service applications. Controlled residual elements for improved weldability.

Certificates

Customer Reviews

"We tested the  pipes and elbows, their performance is very nice. We will make the new purchase plan for the warehouse."

"The pipes are exactly in line with our requirement technically and competitive commercially."

"I am thoroughly impressed with the quality of the seamless pipe fittings provided by JS FITTINGS. Each piece we've received has been meticulously crafted, displaying a standard of workmanship that is truly top-notch."

FAQ

Q: What's the difference between Grade 6 and Grade 8?

A: Grade 8 contains 9% nickel for service down to -320°F, while Grade 6 serves to -50°F. Grade 8 costs significantly more but handles cryogenic applications.

Q: Can these pipes be welded to standard A106 pipes?

A: Yes, but the welding procedure must qualify for the lowest system temperature. Low-hydrogen electrodes are typically required.

Q: Do you provide impact test certificates?

A: Every heat lot includes Charpy impact test results at the specified temperature. Three specimens minimum per ASTM A333 requirements.

Q: What's your delivery time for large orders?

A: Standard sizes ship within 15-20 days. Special sizes require 25-35 days depending on heat treatment scheduling.
