Stainless Steel Seamless Pipe Specifications in Malaysia

There are standard specifications for general stainless steel seamless pipes in the Malaysian market. The stainless steel seamless pipes we export to the Malaysian market are basically produced according to Chinese standards.

A. According to GB14975-94 "Stainless Steel Seamless Steel Pipe", the steel pipe usually has a length (indeterminate length) of 1.5-10m for hot-rolled steel pipe, and hot-extruded steel pipe is equal to and greater than 1m. For cold drawn (rolled) steel pipes with a wall thickness of 0.5 to 1.0 mm, 1.0 to 7 m; for those with a wall thickness greater than 1.0 mm, 1.5 to 8 m.

B. There are 45 kinds of hot-rolled (hot-extruded) steel pipes with a diameter of 54 to 480mm; a total of 36 kinds of wall thicknesses of 4.5 to 45mm. There are 65 types of cold-drawn (rolled) steel pipes with a diameter of 6 to 200mm; a total of 39 types with a wall thickness of 0.5 to 21mm.

C. There should be no cracks, folds, cracks, cracks, folds, delaminations and scarring defects on the inner and outer surfaces of the steel pipe. These defects should be completely removed (except for pipes for machining). After removal, the wall thickness and external Diameter exceeds negative deviation. Other minor surface defects that do not exceed the allowable negative deviation may not be removed.

D. The allowable depth of the straight road. Hot-rolled and hot-extruded steel pipes, with diameters less than or equal to 140mm, are not greater than 5% of the nominal wall thickness, and the maximum depth is not greater than 0.5mm; cold-drawn (rolled) steel pipes are not greater than 4% of the nominal wall thickness, and the maximum depth is not greater than 0.3 mm.

E. Both ends of the steel pipe should be cut at right angles, and the burrs should be removed.

Therefore, when we purchase stainless steel seamless pipes, we must pay attention to the above specifications and details, so that we can do a better job in the Malaysian market.

Manufacturing Process of Stainless Steel Seamless Pipe in Malaysia

1. Hot rolling (extruded seamless steel pipe): round tube billet → heating → perforation → three-roll skew rolling, continuous rolling or extrusion → pipe removal → sizing (or diameter reduction) → cooling → straightening → hydraulic test (or flaw detection)→marking→warehousing

The raw material for rolling seamless tubes is a round tube blank, which is cut by a cutting machine into a billet with a length of about 1 meter, and sent to a furnace for heating through a conveyor belt. The billets are fed into the furnace and heated at about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key issue. After the round tube blank is released from the furnace, it must be pierced by a pressure piercer. Generally, the more common punching machine is the conical roller punching machine. This kind of punching machine has high production efficiency, good product quality, large amount of perforation and diameter expansion, and can wear a variety of steel grades. After perforation, the round tube blank is successively cross-rolled, continuously rolled or extruded by three rolls. After extrusion, the tube should be removed and sizing. The sizing machine rotates into the steel billet at high speed through the conical drill bit to punch holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter of the drill bit of the sizing machine. After the steel pipe is sizing, it enters the cooling tower and is cooled by water spray. After the steel pipe is cooled, it will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. After the steel pipe quality inspection, it must pass strict manual selection. After the quality inspection of the steel pipe, the serial number, specification, production batch number, etc. are sprayed with paint. And lifted into the warehouse by crane. 

The above is the manufacturing process and process of our stainless steel seamless pipes exported to the Malaysian market.

3. Fluid transportation of stainless steel seamless pipes in Malaysia such as water and gas

Stainless steel pipes and their water delivery equipment are the most advanced basic water purification materials in the world today. They have strong anti-corrosion properties, which cannot be compared with cast iron pipes, carbon steel pipes, and plastic pipes.

The best material for water industry such as water preparation, storage, transportation, purification, regeneration, seawater desalination, etc. The annual demand in Malaysia is about 5,000 tons.

4. Stainless steel seamless pipe equipment manufacturing and maintenance in Malaysia

The annual consumption of stainless steel pipes in Malaysia is more than 3,000 tons. Such industries mainly use sanitary or antibacterial grade stainless steel pipes. Hygienic seamless pipes made of SUS304 and 316L produced in Malaysia can meet the special requirements of various media in the fields of food and biopharmaceuticals. Antibacterial stainless steel has the advantages of stainless steel and good antibacterial properties in kitchen equipment, workbenches in the food industry.

Application and Prospect of Stainless Steel Seamless Pipe in Malaysia

Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, economical and applicable. The thin-walled pipes and the successful development of new reliable, simple and convenient connection methods make them have more irreplaceable advantages of other pipes, and their applications in engineering will be more and more. , the use will become more and more popular, and the prospects for Malaysia are promising.

With the implementation of Malaysia's reform and opening-up policy, the national economy has achieved rapid growth, and a large number of urban housing, public buildings and tourist facilities have been built, which has put forward new requirements for hot water supply and domestic water supply. In particular, the issue of water quality has been paid more and more attention by people, and the requirements have been continuously improved. Galvanized steel pipe, a common pipe material due to its corrosiveness, will gradually withdraw from the stage of history under the influence of relevant policies in Malaysia. Plastic pipes, composite pipes and copper pipes have become commonly used pipes in pipeline systems. However, in many cases, stainless steel pipes are more advantageous, especially thin-walled stainless steel pipes with a wall thickness of only 0.6 to 1.2 mm are used in high-quality drinking water systems, hot water systems and water supply systems that put safety and hygiene first. Safe and reliable, hygienic and environmentally friendly, economical and applicable. It has been proved by engineering practice in Malaysia and abroad as one of the best, new, energy-saving and environmentally friendly pipes in the water supply system. Unparalleled effect.

In Malaysia's building water supply piping system, since galvanized steel pipes have ended a glorious history of a hundred years, various new types of plastic pipes and composite pipes have developed rapidly. The needs of the piping system and the national requirements for drinking water and related water quality. Therefore, relevant experts predict that the building water supply pipes will eventually return to the era of metal pipes. According to the application experience abroad, the thin-walled stainless steel pipe is identified as one of the pipes with the best comprehensive performance among the metal pipes.
