1.Scope

1.1This specification covers nominal (average) wall seamless alloy-steel pipe intended for high-temperature service (Mote 1). Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.

NOTE 1 Α Appendix X1 lists the sizes and wall thicknesses of pipe which may be obtained under current commercial practice.

1.2 Several grades of ferritic steels (Note 2) are covered. Their compositions are given in Table 1.
Note 2
ΑFerritic steels in this specification are defined as low and intermediate-alloy steels containing up to and including 10% chromium.
1.3 Supplementary requirements (S1 to S7) of an optional nature are provided. These supplementary requirements call for additional tests to be made, and when desired, shall be so stated in the order together with the number of such tests required.
1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with specification. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.

Note 3ΑThe dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size," and "nominal size."

Packing:
Our packing can meet any needs of the customers.
How to packing the seamless pipe:
There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.
The Packing Works for Steel Flanges
Steel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc.
The Rust Prevention for Steel Flanges
The normal rust prevention treatment for steel flanges include yellow (Golden) paint Coating, black paint coating or black phosphating treatment, varnish paint coating, varnish antirust oil coating, electro galvanizing coating (Cold), hot dip galvanizing coating etc.
The Packing Works for Steel Flanges
Steel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc. Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually use plywood pallet or plywood case or box to pack steel flanges without fumigation treatment. Whatever plywood or iron & steel packing way, they must be seaworthy, strong, waterproof and easy for loading and unloading.
Shipping mark stick to outside of package.
How better packaging the abrasion resistant pipe
There are probably hundreds of different methods for packing a abrasion resistant pipe and Elbows, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.
Which ways can prevent damage to steel pipes during transport?
The compartment for the pipes should be clean inside. We have to ensure that there is no stone, brick and other hard objects to avoid damage for steel tubes.
For bundling steel pipes, we should put some sleepers in the bottom of compartment. For the flat-bed vehicles, we have to install protective rubber mats to protect steel tubes. When steel pipes are sent to the warehouse, we should put at least two sleepers or crossties vertical to pipes.
For long distance transportation of steel pipes, we should tie them tightly. If we use steel wires or hard objects to bundle steel pipes, the protective rubber is usually often placed in the steel strapping to prevent surface damage.
What is the material and technical process of seamless steel pipes?
In market there are various kinds of materials to manufacture seamless steel pipes. The seamless steel pipes made from 40Cr carbon steel are applied in manufacturing machinery force components.
There are two methods to process steel pipe: hot-rolled and cold rolled.
Generally, the seamless steel pipes are tested strength and flattening before leaving factory. In addition, seamless steel tubes are required to have high strength, high resistance to oxidation corrosion and good organizational stability. Therefore, the steel pipe manufacturing process is quite strict.
What are the key functions of seamless steel tubes?
Structural steel pipe is mainly used in general and mechanical structure.
Fluid pipe is mainly used in major projects and large scale equipment for delivering fluid like water and oil.
High pressure boiler steel seamless pipe is mainly applied in nuclear power plant boiler tanks that are resistant to high temperature and high pressure.
Marine seamless steel tube is mainly applied in ship boiler and superheater.
Petroleum seamless steel tubes are mainly used in boiler, heat exchanger for conveying fluid.
Twenty-five safety tips for Steel and Pipes
Steel building materials come in a wide variety of forms that include flat plate, coil, round and squared bars, beams, pipes, and many other shapes. Each type of steel you work with requires its own unique method of handling, storage, and transporting. There are numerous specialized fittings, attachments, and implements used to handle steel, such as chains, clamps, and hooks. All must be inspected before use and maintained and stored properly to ensure safety.
All of your equipment must be used properly to keep the material being handled from slipping, or the equipment from failing. I am going to list the top 25 key requirements to protect employees from the hazards associated with steel erection activities, whether it’s construction, or repair of single or multi-story buildings and bridges, or other structures where steel erection occurs.
  1. Employees using any type of lifting or handling equipment must be competent, and if required, certified in its use.
  2. When handling steel material, appropriate Personal Protective Equipment such as hard hats, steel toed boots, and gloves must be worn.
  3. Cranes, forklifts, or hoists used to handle steel must be load-rated for the job. Equipment limits and load charts must be prominently displayed.
  4. Lifting attachments such as spreader bars, chains, sling hooks, and plate clamps must be load-rated sufficient for the job.
  5. Plate or dog clamps must be used to lift only one piece of steel at a time.
  6. When using chain shorteners. If installed improperly, or of insufficient load-rating, the chain may fail causing the load to fall.
  7. Web slings must be appropriately load-rated and must be protected from contact with any sharp edges.
  8. Ensure that the crane or hoist is positioned directly over the load to prevent the load from swinging as it clears the floor or ground.
  9. The storage of steel material presents many potential hazards. The steel may roll, slip, slide, or fall over if not properly restrained while stored. Shelves or racking may collapse if system is not suitably designed for the purpose.
  10. Racking or shelving systems must be cross-braced to prevent collapse.
  11. Bollard posts should be installed to prevent damage to storage systems by forklifts or equipment.
  12. The safe load capacity of storage systems should be clearly displayed in prominent locations on the system.
  13. Personnel involved in storing and handling steel should be knowledgeable in weights of steel in any form they are handling.
  14. Steel plate stored on-end or upright should be offset to help facilitate the use of plate clamps for handling.
  15. Round bar, pipe and steel coil may be stored in racks if they are inclined or stops are provided to prevent material from rolling off.
  16. Large steel pipe should be stored lying flat and chocked, or secured in cradle racks. These pipes should always be transported in pipe cradles.
  17. Coil steel is one of many versatile forms of steel and comes in a great variety of sizes and weights; some may weigh up to 15 tons. There is a hazard of violent whipping movement if the coil is allowed to uncoil without restraint. Coiled steel rolls easily, even in high weights. Therefore, there is a great potential for serious injury or even fatal accidents if coil steel is not handled and stored properly.
  18. Larger coils must be stacked on the bottom row – or their weight will push apart the smaller coil underneath, creating a potentially lethal hazard.
  19. Coil steel should be transported in cradles the same as large diameter steel pipe.
  20. Steel is commonly transported on flatbed trucks and semi-trailers. Trucks should be provided with headboards (headache racks) suitable to protect the driver from the load moving forward, and a tail board to protect other drivers from loose material.
  21. Stanchion pins suitable to the load should be place in the rail-post pockets to guard against sideward movement of the load.
  22. Trucks regularly used to transport steel should be provided with a catwalk that has grab rails between the cab and the headboard to provide a safe vantage point to direct loading and unloading operations. Drivers must check the load frequently to ensure the load has not shifted or settled, allowing slack in binding chains or loosening of the material.
  23. Chains used to secure the load and tie down the steel material for transport must be properly load rated.
  24. Never unload material with the transport truck parked on an uneven surface. If the facilities at the destination are not suitable for unloading, the driver should notify superiors and ensure that safe arrangements can be made for unloading.
  25. When unloading steel, especially pipe or coil, stanchion pins should be left in place and binders loosened slowly, one at a time, but not entirely removed until all binding chains are loosened and there is no signs that shifting of the load has occurred. While unloading, material should be re-secured between lifts to prevent load-shift hazards.
Steel should always be handled carefully and slowly in any situation. Respect its weight and the destructive capability of the weight in motion. Do not compromise safety to speed up handling processes.
