ASTM A312 Precision Welded or Seamless 201 202 304 304L 316 316L Stainless Steel Pipe Tube

ASTM A312 Precision Welded or Seamless 201 202 304 304L 316 316L Stainless Steel Pipe

TORICH is a professional manfucaturer of precision Stainless Steel Tubes. Our high precision stainless steel tubes with good processing performance and high toughness, which are widely used in industry, furniture decoration industry and food and medical industry.

ASTM A312 Standard is seamless pipe specification, also covering welded pipe, seamless pipe is used for high temperature and general service, manufacturing seamless pipe have no any welding process, that is why seamless pipe provides better properties than welded pipe.

Surface Conditions:

Bright Annealed / Polished / Annealed&Pickled / Bright Annealed+Fine polishing / Electropolishing

Applications:

Electric heater fields like metal tube heater,hot runner,thermostat,heating apparatus,air conditioning,refrigerators and other household appliances,heating etc. Food and beverage,petroleum chemicalindustry,heat exchanger,condenser,marine environment,paper making,chemical fertilizer,instrumentation, medical,Automotive engineering,aerospace,pipe structure,priting textile and etc.

Advantages:

Sophisticated bright annealing technology makes the tube good mechanical performance,the tube can be flared,flatten,bent freely.
