Seamless Ferritic Alloy Steel Pipe for High-Temperature Service is define by Standard ASTM A335. The ordered ASTM A335 pipe must be suitable for fusion welding, bending, and other similar forming operations. Design, service environment, and mechanical characteristics will all affect selection.

High-Temperature Seamless Ferritic Alloy Steel Pipe.

Standards: high-temperature and ASTM A335/335M (ASME SA335/SA335M) properties

Common Size (mm):
Outer Dimensions: 19.05mm ~ 114.3mm
Wall Thickness:2.0mm ~ 14 mm
Length: max 16000mm

P11, P12, P22, and P5 are the primary steel grades use in manufacturing.

The following packing options are available: bare packing, bundle packing, crate packing, wooden protection at both ends of tubes, or as requested.

Similarly Chemical composition analysis, mechanical properties testing (including tensile strength, yield strength, elongation, flaring, flattening, bending, hardness, and impact testing), and other inspection and testing Hydrostatic testing, non-destructive testing, and surface and dimension testing.

Oil-dip, varnish, passivation, phosphating, and shot-blasting are surface treatments.

However Each crate’s order number, heat number, dimensions, weight, and bundles—or other information—are marked on both ends.

Seamless ferritic alloy steel pipe for high-temperature service is cover by this specification. The pipe must be capable of fusion welding as well as bending, flanging, and other similar forming operations. Similarly the chemical composition, tensile properties, and hardness requirements for the steel material must be met. Each pipe length must go through the hydro static test. Additionally, each pipe must be check using a non-destructive examination technique in accordance with the prescribed procedures. The scope of each practice’s restrictions must be taken into consideration when determining the range of pipe sizes that may be examined. Present are the various mechanical test specifications for pipes, including the transverse or longitudinal tension test, flattening test, and hardness or bend test.

Ronggangpipe.com is an experienced pipe company that offers broad types of pipes to fulfill people’s needs. ERW Pipes are derive from solid steel in sheet or bar form and formed into a solid round shape. It is form by drawing a solid billet over a piercing rod to create the hollow shell without welding or seam. The pipes are thinner and lighter than welded ones, and they also have a uniform shape as they are manufacture of uniform extrusion of an alloy. The pipes are manufacture of stainless steel materials. There are different stainless steel grades.

Carbon steel pipe is compose as an outcome of carbon and iron. It is pipes that are cast in such methods that they do not leave any seams to weaken the pipes. Such a kind is refer to as seamless steel pipe. Seamless pipes are prepare using an extrusion mold. It is because, since the seamless pipe has a continuous extrusion of the alloy, there is an added advantage of roundness in its circumference. Therefore, carbon steel is the most cost-effective alloying material in the market.

LSAW Pipes are manufacture by cutting, bending, and welding steel plates. The pipes are divide into high-frequency resistance welding and submerge. The pipes are produce by molding steel sheets to a cylinder and joining the ends together by welding in a straight line.

Ronggangpipe.com is one of the suppliers of Welded Steel Pipe. Therefore, we are obligate to meet the quality standards per the customer demand. The pipes are manufacture from spiral submerge arc welded steel plates. Steel pipes are typically use in the oil and gas industry for exploration. The pipes are submerge arc weld, commonly refer to as large-diameter weld pipes, manufactured by the submerge arc welding process.

ASTM A335 is generally name chrome molly pipe for the chemical elements- Molybdenum and Chromium. The pipe specification covers nominal wall and minimum wall thickness pipe with alloy material and manufactured in seamless type. It is the standard seamless ferritic alloy steel pipe specification for high-temperature service. Therefore, the seamless ferritic alloy steel pipe is use in high-temperature services and the boiler industry. It is also use in different industries.

ASTM A213 is seamless ferritic steel and austenitic alloy SS tubing used in boilers for superheaters and heat exchangers. The specification covers seamless ferritic and austenitic steel boiler, superheated, and heat-exchanger tubes. However, it is a standard specification for seamless tubes use in heat exchanger systems and covering. It applies to seamless ferritic and austenitic pipes with the minimum thickness in boiler and superheated. We focus on providing high-quality and affordable products to our clients.
