 Stainless Steel

It is a common misconception that stainless steel is stronger than regular steel. In fact, due to the low carbon content, stainless steel cannot be hardened. Therefore, when compared with regular steel it is slightly stronger than an un-hardened (grade 2) steel fastener but significantly weaker than hardened steel fasteners. Stainless steel is also much less magnetic than regular steel fasteners though some grades will be slightly magnetic. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced sturdiness and increased corrosion resistance. As an element, Stainless steel is 100% recyclable, corrosion resistant, conserving-free, tenacious and hygienic. Stainless steels are iron alloys that contain a minimum of 10.5% chromium, other elements are added to enhance the structure and properties like form ability, strength and cryogenic toughness of the material. The material is corrosion resistant, manageable and possesses long time durability along with visually aesthetic appearances. Temperature and exposure to harsh climates are easily sustained by the material. Without a doubt an all in one metal because of its properties.

Butt Weld Fitting

A pipe fitting defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system. There are many different types of fittings and they are the same in all sizes and schedules as the pipe. Butt weld (BW) fittings whose dimensions, dimensional tolerances et cetera are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43.

BEVELLED ENDS: The ends of all butt weld fittings are bevelled, exceeding wall thickness 4 mm for austenitic stainless steel, or 5 mm for ferritic stainless steel. The shape of the bevel depending upon the actual wall thickness. This bevelled ends are needed to be able to make a “Butt weld”.

We produce large volume at crest in a 3-shift plan, which means, we used to target 1.3 million assembled units on per month basis. We have in house testing provision e.g. Hardness Test, PMI Machine, Ultrasonic Testing, Mechanical test, Spectro machine, Hydrostatic Testing, manual inspection of gauge and Pressure testing. Our production varies from snubber, condensate pots, manifolds, instrumentation valves and custom designed valves. Tube Fittings Manufacturers can be fabricated in threads like NPT, BSPT & BSPP.

Stainless Steel Butt Weld Fitting is made from precipitation hardened grade stainless including A286 Stainless are particularly useful in applications such as outdoor equipment, medical devices and chemical and food processing equipment or anywhere corrosive element exposure is possible. These kinds of Butt Weld Fitting are also commonly used for Commercial aspects, Home Appliances, Vehicle parts, and also for aluminum or steel made furniture. Stainless Steel Butt Weld Fitting is used in surgical instruments and also Industrial equipment as the resistance to corrosion is a major advantage. They are also used as an aerospace structural alloy and also as a component for the construction of large buildings.
