# ─────────────────────────────────────────────
[faq_topics]
# Common engineering questions with recommended pages
# ─────────────────────────────────────────────

what_is_expansion_joint:
  q_en: What is an expansion joint and when is it needed?
  q_th: ข้อต่อขยายตัวคืออะไร และเมื่อไหร่ควรใช้?
  answer_hint: Used to absorb thermal expansion, vibration, and pipe misalignment. Required wherever pipe temperature changes, equipment vibration must be isolated, or differential settlement is expected.
  see: /rubber-expansion-flexible-joint/, /solution/

rubber_vs_metal_joint:
  q_en: What is the difference between a rubber and a metal expansion joint?
  q_th: ความแตกต่างระหว่างข้อต่อยางและข้อต่อโลหะคืออะไร?
  answer_hint: Rubber joints are better for vibration absorption and lower cost; metal joints handle higher temperatures (up to 450°C), higher pressure, and chemically aggressive media. Use metal when temperature exceeds ~110°C or where rubber is chemically incompatible.
  see: /rubber-expansion-flexible-joint/, /metal-expansion-joint-flexible-hose/

rubber_vs_ptfe:
  q_en: When should I use PTFE instead of rubber expansion joint?
  q_th: เมื่อไหร่ควรใช้ PTFE แทนยาง?
  answer_hint: Use PTFE when the fluid is a corrosive chemical, acid, solvent, or pharmaceutical-grade fluid that would degrade rubber. PTFE is chemically inert to virtually all media.
  see: /ptfe-tpu-expansion-joint-flexible-hose/

how_to_select_isolator:
  q_en: How do I select the right vibration isolator?
  q_th: วิธีเลือก Vibration Isolator ที่เหมาะสม
  answer_hint: Need equipment weight (kg), number of mounting points, and operating RPM. Higher deflection needed for lower RPM. Use the online calculator or contact Tozen engineering.
  see: /vibration-isolator-calculation/, /floor-mounted-vibration-isolator/

floor_vs_hanger_isolator:
  q_en: What is the difference between a floor-mounted and hanger vibration isolator?
  q_th: ความแตกต่างระหว่าง Vibration Isolator แบบตั้งพื้นและแบบแขวน
  answer_hint: Floor-mounted isolators (PTM series) go under equipment on the floor or inertia base. Hanger isolators (PTH series) go inline with pipe or duct suspension rods to prevent vibration from travelling along suspended piping.
  see: /floor-mounted-vibration-isolator/, /vibration-isolating-hanger/

deflection_25_50_75:
  q_en: What does 25mm / 50mm / 75mm deflection mean for a vibration isolator?
  q_th: ค่า Deflection 25/50/75mm ของ Vibration Isolator หมายความว่าอะไร?
  answer_hint: Static deflection is how much the isolator compresses under load. Higher deflection gives better isolation at lower frequencies. 25mm suits high-speed equipment (≥700 RPM); 50mm suits medium-speed (≥500 RPM); 75mm suits low-speed or sensitive locations (≥400 RPM).
  see: /vibration-isolator-calculation/

how_to_select_valve:
  q_en: How do I choose the right valve type for my system?
  q_th: วิธีเลือกวาล์วให้เหมาะกับระบบ
  answer_hint: Gate valve for full-open/full-close isolation; butterfly valve for larger DN isolation with compact face-to-face; ball valve for small-bore quarter-turn isolation; check valve for backflow prevention; PRV for pressure reduction; motorized valve for automatic BMS control.
  see: /manual-operated-valve/, /motorized-control-valve/

butterfly_vs_ball_vs_gate:
  q_en: Butterfly valve vs ball valve vs gate valve — which should I use?
  q_th: เปรียบเทียบวาล์วผีเสื้อ บอลวาล์ว และเกทวาล์ว
  answer_hint: Butterfly: large DN (≥DN50), low face-to-face, moderate pressure, HVAC/water. Ball: small DN (DN15–50), tight shut-off, high pressure, general service. Gate: full-bore, minimal pressure drop, large DN water/steam isolation.
  see: /manual-operated-valve/

what_is_prv:
  q_en: What is a Pressure Reducing Valve (PRV) and how does it work?
  q_th: วาล์วลดแรงดัน PRV คืออะไร และทำงานอย่างไร?
  answer_hint: A PRV automatically reduces upstream pressure to a lower, constant downstream setpoint regardless of demand fluctuation. Used in high-rise buildings, domestic water supply, and systems where supply pressure exceeds equipment rating.
  see: /prv-valve/

how_to_select_pump:
  q_en: How do I select a booster pump or multistage pump?
  q_th: วิธีเลือกปั๊มน้ำและปั๊มเพิ่มแรงดัน
  answer_hint: Need design flow rate (m³/h or LPM) and required total head (m) or pressure (bar). Contact Tozen sales with these values for sizing assistance.
  see: /vertical-multistage-pump-system/, /request-a-quote/

seismic_protection_guide:
  q_en: How do I protect a piping system from earthquakes?
  q_th: วิธีป้องกันระบบท่อจากแผ่นดินไหว
  answer_hint: Use flexible expansion joints at equipment connections to absorb seismic movement. Combine with properly designed supports and seismic restraints. Tozen provides flexible joints suitable for seismic zones.
  see: /seismic-protection/, /rubber-expansion-flexible-joint/, /metal-expansion-joint-flexible-hose/

download_drawing_cad:
  q_en: How do I download CAD drawings or 3D models?
  q_th: วิธีดาวน์โหลดแบบ CAD และโมเดล 3D
  answer_hint: Visit the Drawing Download section. 2D master drawings, 3D STEP/IGES models, and AutoCAD block DWGs are available for most products. Registration may be required.
